Compare LG OLED B6 vs Hisense U7S / U77SE

The LG OLED B6 is a very successful continuation of the B series and a TV that makes a lot of sense as a first step into OLED. It doesn't try to compete with the most expensive models in every respect, but on the most important points it still delivers exactly what many people choose the technology for: perfect black, very high contrast, and a picture that can simply look spectacular in movies. This is largely thanks to the new budget WOLED panel, called OLED SE. Thanks to it, LG's cheapest OLED is now noticeably brighter than a few years ago, and around 800 nits in HDR is a level you can actually notice while watching. Bright elements have more punch, the picture handles more demanding scenes better, and combined with OLED blacks the whole thing can look really impressive. Movies and series from streaming platforms fare especially well, particularly those available in Dolby Vision. That's when the B6 makes the most of its capabilities and can produce a picture that will be a big step up for someone moving from a typical LCD TV. However, it's not a model without compromises. Our biggest reservation is how the screen handles reflections. The lack of a classic polarizer means the TV fares much worse when placed opposite a large window or a strong light source. Reflections are more noticeable than on other WOLED panels, and the black itself loses some of its character in a bright room. In controlled viewing conditions this won't be an issue, but for a very bright living room you should approach this purchase with some caution. The operation of webOS also leaves something to be desired. It is still very good overall, with a rich app library, a convenient Magic Remote, and pretty much everything you'd expect from a modern smart TV. The problem is that on the B6 it doesn't always run as smoothly as it should. At times you can tell the new version of the system is more demanding and a bit "heavier" than before. Despite these notes, the LG B6 still performs very well. It's a TV that delivers all the key advantages of OLED while not costing as much as the higher-end models. It makes the most sense when it turns up on a good sale, because that's when it can be one of the most interesting choices for people who want to get into OLEDs without overpaying.

Hisense U7S is the latest iteration of the U7 series, whose biggest advantage remains its price-to-quality ratio. You get a Mini LED TV with local dimming, which really improves black levels and gives the picture depth for evening viewing. During the day, the generous brightness headroom is useful, so you don't have to immediately cover the windows. It's not a device without compromises, but as an everyday TV it makes a lot of sense. Gamers benefit a lot as well. The U7S supports high refresh rates from consoles and PCs, has an extensive set of gaming features, and responds very quickly to controller input. Pleasingly, the low input lag is preserved in Dolby Vision too. Add in the smoothly running VIDAA, which offers both Smart features and handy extras for regular TV, and the package is fairly versatile, though compared with last year's U7Q it's hard to call it a big step forward. Unfortunately there are also things that clearly bother us. The first is motion blur. The panel has a high refresh rate, but its pixels don't always keep up, so visible trails follow moving objects. Fans of sports and fast-paced games will notice this especially. The second issue is HDR, which the TV shows somewhat "its own way." Instead of sticking to the brightness encoded in the content, it strongly brightens parts of the image. That was probably meant to look more impressive, but it often has the opposite effect: the scene becomes over-bright, loses depth, and clearly departs from the creators' intent. It's a shame this behavior can't be effectively corrected even during calibration. Despite these remarks, the U7S remains an interesting choice if you're looking to get as much as possible for a reasonable price. Compared with basic LCDs without local dimming, which you can still find at a similar price, it primarily offers much better blacks. And that's exactly its greatest strength. You don't have to reach for an expensive model to get a Mini LED whose advantages are actually noticeable when watching. If you accept its flaws, the Hisense U7S can above all be a cost-effective purchase.

Black levels on the LG OLED B6 are perfect. That's no surprise, since it's an OLED (WOLED), but this is where you can really see why this technology still has so many fans. Each pixel can turn off individually, so in dark scenes there's no gray haze or light bleed around bright elements. That gives the image excellent depth and can make it look truly three-dimensional. Shadow detail also holds up well. Nothing blends into one dark blotch, and fine details remain visible even in more challenging scenes. In that respect, the B6 simply showcases everything we love about OLED TVs.

The Hisense U7S shows good black levels, especially for one of the entry-level Mini LED models. The 55-inch unit we tested uses 192 local dimming zones that work well with the VA panel. In most of our scenes contrast ranged from about 21,000:1 to over 51,000:1, and in one it even exceeded 500,000:1. In many films you can see it — dark scenes have depth, and blacks don't glow gray like on many cheaper LCDs without local dimming.

It gets worse when the screen contains a lot of small bright objects on a dark background (for example, in the scene shown below). There aren't enough zones to illuminate each one separately, so you can see a bright halo around the small objects. This so-called halo effect is easiest to notice when watching in a dark room. In the most demanding shot contrast fell to about 5,650:1, and here the backlight limitations are clearly visible. Even so, given the TV's class, it's hard to call this a fault, because many Mini LED TVs in a similar price range will have similar problems.

The LG B6 is a moderately bright OLED. After calibration it reaches about 800 nits, roughly 200 nits more than last year’s B5. That’s thanks to the new budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR in many scenes look fuller than on last year’s lower-tier OLEDs. That doesn’t mean the B6 has no limits. In very bright shots, when a large part of the screen is strongly lit, brightness can drop below 400 nits. This behavior is typical for OLED TVs (especially those from this segment) and that’s when you see the biggest difference versus more expensive models. All things considered, we rate the B6’s results as really solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that you can really feel the step up from ordinary SDR in films.

Color gamut

Using the OLED SE panel has slightly affected wide color gamut coverage. Compared with last year’s model, results fell by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn’t mean the colors on the LG B6 are weak. In most movies and series they look lively, well saturated and simply pleasing to the eye. You only notice a difference in very bright, highly colorful scenes. Then colors lose some intensity compared with QD-OLED panels. This comes from the WOLED panel construction. Besides red, green and blue subpixels it also uses a white subpixel that helps boost brightness. It comes at a cost: at very high luminance some color is effectively “diluted” by the white light, so saturation of some colors can be slightly lower. In everyday use this isn’t a big issue, but you can notice it in the most demanding scenes.

The Hisense U7S has considerable HDR potential, but it can't use it in every scene. On a test pattern it reaches around 1,100 nits, so the backlight itself is very strong. In our brighter film scenes we measured about 640 to 745 nits. That's still enough for the sun or bright highlights to have a noticeable glow and to show an advantage over SDR material. When the TV needs to illuminate a larger portion of the image, it does quite well.

The problem appears with small lights on a dark background. Each of the 192 zones covers an area much larger than a tiny point on the screen. If the TV were to strongly light such a zone, it would also brighten the surrounding area along with the light. Hisense tries to avoid that and dims the entire zone. Black levels therefore look better, but a small bright object that should draw the eye also loses intensity. That's why in two tougher scenes we recorded only 297 and 154 nits. The difference is large: in one shot HDR can impress, and in the next small lights are noticeably muted. The U7S therefore prioritizes maintaining deep blacks, even at the expense of bright details. With this number of zones that's an understandable compromise, but it's worth remembering — the 1,100-nit peak tells us about the backlight's capability, not how brightly the TV will render every element of a film.

Colors

Hisense calls the U7S ULED, but that's a marketing name; the wider color gamut here comes from a PFS phosphor backlight. In our measurements the TV covered about 91% of DCI-P3 and 71% of BT.2020. Those are good results, although it falls short of the best screens on the market. The biggest shortfall is in green — the TV doesn't even reach the DCI-P3 target there, so the most saturated shades will be less intense than they should be. Most colors in HDR films and series, however, still look suitably rich. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

We tested the LG B6 in Filmmaker Mode, which is the best picture setting available right out of the box. ISF modes deliver very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of those modes is, after all, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. With SDR content, the factory settings perform really well. Color errors are small, gamma behaves properly, and the image looks natural during ordinary viewing and does not seem overly "pumped up." It's a bit worse with HDR. When you play that kind of content you can quickly see that the white balance hasn't been set perfectly. Too much blue and red causes the image to shift toward a slightly pink tint. This is also confirmed by measurements of the color gamut and the ColorChecker, where samples clearly drift in that direction. It's not a flaw that completely ruins the picture, but you can notice it in HDR films. So people who care about the most faithful image should consider the calibration we describe later in the review.

The out-of-the-box colors on the Hisense U7S are decent, but there are a few things to improve. In SDR there's a red bias in the white balance, which makes the image too warm and in places slightly pink. You can notice this on faces and on bright, neutral surfaces. Gamma also runs below the reference, so the TV brightens the image, especially in darker areas. That makes shadow details easier to see, but the scene loses some of its depth.

In HDR the white balance is a bit more even, but not completely neutral; midtones lack blue, and the brightest areas lack red. A bigger problem is how brightness is reproduced. The EOTF curve shows that a large portion of midtones is being brightened, so the image looks brighter than the source material intends. Color Checker measurements also perform worse than in SDR: many errors are around 3 to 4, and individual ones reach as high as 8. Colors can therefore look attractive, but they are not always faithful to what we should be seeing. There's room for improvement, and we'll check how much can be corrected with calibration.

During calibration we focused primarily on HDR content, because that's where the factory settings required the biggest corrections. We didn't neglect SDR mode, though, which after adjustment was brought almost to perfection. Colors are very accurate and brightness is handled as it should be. The biggest improvement in HDR came from correcting the white balance. After removing the excess red and blue, the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colors that had been shifting toward magenta improved. After calibration most errors fell below a Delta E of 2–3, the threshold at which the average viewer stops noticing differences with the naked eye. The LG B6 can therefore deliver a very accurate image, especially for the manufacturer's entry-level OLED model.

Calibration of the Hisense U7S helped most with SDR content. We managed to even out the white balance, so the previous warm cast is gone and whites and grays look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the image unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors fall below 2. That yields a really well-calibrated picture for regular TV and SDR movies. It didn't go as smoothly in HDR. The TV lacks an effective way to correct the EOTF curve, so Hisense still interprets the content's brightness a bit on its own. It brightens parts of the image and can dim the brightest elements depending on the scene and the local dimming behavior. Calibration couldn't eliminate this. It shows up in the Color Checker results as well, where many errors remain around 3–4 and individual ones exceed 7. So in SDR the result is very good, but in HDR we have to accept that the TV adds its own interpretation of brightness to the image.

Tonal transitions on the LG B6 are quite good, though you can still see some limitations typical of WOLED panels. In most scenes, colors transition smoothly between shades, without noticeable banding or unwanted digital artifacts. It's not always perfect, however. Most problems appear in the dark areas of the image, where WOLED panels have long been somewhat weaker. This is partly due to the greater difficulty of driving the panel at very low brightness and to the design's use of a white subpixel. Compared with last year's model there is a slight improvement, but it still doesn't reach the level of the best QD-OLED TVs or more advanced LCD models.

The smoothness of tonal transitions is one of the Hisense U7S’s stronger points. HDR10 material performs especially well, with colors blending gently into one another without noticeable banding. Even in dark scenes it’s hard to find major issues. Minor color stepping is visible only in brighter shots, but during typical viewing it usually doesn’t attract attention. It looks a bit worse in Dolby Vision, where boundaries between shades can be more apparent. That’s why Hisense loses some points from us, although overall this is still a very good result and one of the better performers in its class.

The LG B6 handles lower-quality sources very well. Much of the credit goes to effective digital image processing, which can mask some source imperfections without overly smoothing the whole scene. The feature "Smooth Gradation" proves particularly useful. It can significantly reduce posterization, which we mentioned earlier, especially in darker areas of the image. The safest choice remains Low or Medium. The function still effectively smooths harsh tonal transitions, but does not yet interfere too much with fine details. The most dedicated purists can, of course, leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a good amount of detail, and the image is neither overly sharpened nor excessively blurred. Some limitations become noticeable only with very poor sources below 720p, where the smallest subtitles and fine elements are not always perfectly sharp, but this is true for almost every other TV on the market.

The handling of lower-quality material on the Hisense U7S is fairly mediocre. The Pentonic 700 chipset used here doesn't cope well with the effects of heavy compression. The menu includes a "Smooth & Gradient" picture option, but its performance leaves much to be desired. At the low setting it's hard to notice any improvement in tonal transitions, although at least the image isn't degraded. The medium and high settings still don't remove visible banding between shades and begin to smear details; in our test clips even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you use this feature, we'd stick with the low setting. Its current behavior needs refinement, but that's mainly down to the processor used. Upscaling to 4K performs much better. Lower-resolution footage gains clarity, edges are well reconstructed, and fine elements look crisp. That doesn't mean it can recover details that weren't in the recording, but the TV makes good use of what it gets from the source. Another plus is that it doesn't crop the image edges, even with an SD signal.

One of the biggest advantages of OLED panels is their very fast pixel response time. This keeps the image sharp and prevents the visible smearing that often appears on LCD TVs. However, there is a downside. During slow camera pans, motion can look more choppy than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 you can easily soften this with TruMotion. With the motion smoothing properly adjusted, you can achieve smoother motion without giving the picture an excessive soap-opera effect.

Motion handling on the Hisense U7S is pretty good thanks to the 144 Hz refresh rate. For movies we also have a motion smoothing feature that lets you adjust judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if abrupt camera shifts bother you. In sports and games the high refresh rate is also useful, but unfortunately it doesn't solve this panel's biggest problem.

The culprit is pixel response time. Fast-moving objects leave long, noticeable trails, as our UFO test shows. It's worst on dark backgrounds, where the trail behind the object is especially pronounced. So motion can be smooth, but the moving object itself loses sharpness, and that difference on the U7S is fairly easy to notice.

LG OLED B6 offers a powerful set of advantages for gamers; it's simply a complete platform for PS5, Xbox Series X/S, or a solid PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can skip the annoying cable swapping when you want to connect several newer devices at once. We get the full suite of sync technologies – from classic VRR to G-Sync and FreeSync. The screen seamlessly matches the refresh rate to the frame output produced by the console or graphics card. Of course ALLM is included: the B6 automatically detects a running game and immediately cuts input lag to a minimum. HDR handling is also excellent. The TV supports Dolby Vision, and a properly implemented HGiG standard means that after an initial calibration in the console settings the picture won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on top is the Game Bar. Instead of digging through the full menu during gameplay, one click lets you adjust shadow visibility, tweak selected settings, or simply check the display’s current operating mode. All of this makes the LG B6 a great choice for gamers.

The Hisense U7S has a lot to offer gamers. You get two HDMI 2.1 ports and support for 120 Hz at Full HD, 1440p, and 4K, so modern consoles’ capabilities are well used. When connected to a PC you can use 144 Hz at 4K or switch the resolution to Full HD and run 240 Hz. So there’s a wide choice, although it’s worth remembering the motion smearing mentioned earlier, which the high refresh rate does not eliminate. VRR and ALLM are also present. The first helps prevent tearing when frame rates in a game change. The second automatically switches the TV into game mode, so you don’t have to dig through the menu each time. VRR works from 48 to 240 Hz, with the highest refresh rate available in Full HD. Xbox users can also play in Dolby Vision, including at 120 Hz. Importantly, this format does not introduce significant input lag here. The Game Bar also looks very good. It’s easy to read, visually appealing, and lets you quickly check what signal the TV is receiving. There are also handy gaming settings at your fingertips, including shadow brightening. If it’s hard to spot an opponent in a dark game, you can improve visibility without digging through the entire menu.

Our biggest complaints concern HGiG. Hisense continues to do its own tone mapping, which makes setting HDR on the console confusing. You adjust a checkerboard test pattern and the TV continuously adapts how it looks. As a result, the moment the pattern disappears does not correctly indicate the screen’s brightness limit, and it’s easy to set the value too high. For this model it’s better to set the target HDR peak brightness on the console to about 900 to 1000 nits, rather than relying on the configurator.

Input lag in the LG B6 is very low. At 120 Hz it's about 5 ms, and at 60 Hz it rises to roughly 15 ms. Both results are good enough that most gamers won't notice any delay between their inputs and what happens on screen. Dolby Vision performs a bit worse, where input lag can increase to around 25 ms. That's still not a bad result, but the most demanding players using an Xbox may already feel a difference compared to standard HDR.

In terms of input lag the Hisense U7S performs excellently. At 60 Hz we measured 14–16 ms, and at 120 Hz just 9–10 ms. Input is responsive, and even in fast-paced games the TV doesn't introduce any noticeable delay. Importantly, Dolby Vision performs just as well, with 14 ms at 60 Hz and 9 ms at 120 Hz, so you don't have to give up that format for fear of added latency. The motion smearing described earlier is a separate issue: the panel responds quickly to input, but the pixels don't always keep up with color changes.

The LG B6 also works very well as a computer display. Low input lag, support for VRR, G-Sync and FreeSync, and a high refresh rate mean there's little to fault it for gaming. Compared with pricier models, it only lacks additional modes with even higher refresh rates. In the best OLEDs and some LCD TVs you can now find even 240 or 330 Hz at lower resolutions. The B6 doesn't have that, but for most people it won't be a big loss. What may matter more is the WOLED panel's subpixel structure. Because it uses four subpixels, small fonts in Windows aren't perfectly sharp and you can sometimes see slight colored fringes around them. For occasional web browsing or computer work that probably won't be an issue. However, anyone planning to buy a smaller variant, for example 48 inches, and use it as their main monitor at a desk should keep that in mind.

When connected to a PC, you can use 4K at 144 Hz with G-Sync enabled and about 10 ms of input lag. It's a good setup for gaming, although panel smearing is still noticeable in fast-moving scenes. Chroma 4:4:4 also works correctly, even at the maximum refresh rate, so colorful on-screen text and small desktop elements remain legible.

The U7S is quite suitable for web browsing or occasional work, but not all fonts look equally sharp. Our main issue is with small, dark text: thin parts of letters can disappear and characters look uneven. It's hard to notice from the couch, but when working up close, especially with text or spreadsheets, it can be distracting.

Viewing angles on the LG B6 are very good, which is typical for almost all OLED TVs. Even at extreme side angles the picture maintains strong color saturation and doesn't noticeably lose brightness. In this respect, really only models with QD-OLED panels perform better. However, there's one thing worth mentioning. Some WOLED panels may show a slight greenish tint at extreme angles. This isn't a rule; some units exhibit the effect more, others hardly at all. It depends on the specific unit.

Viewing angles are unfortunately a weak point of the Hisense U7S. As soon as you move to the side, colors lose saturation, blacks become lighter, and the picture looks washed out. At a 45-degree angle we measured a 74% drop in brightness, so the difference compared with watching head-on is really large. That's a typical limitation of VA panels. When sitting centrally you can appreciate its strong contrast, but people seated at the far ends of a wide couch will see a noticeably weaker picture. The U7S is therefore best suited to setups where viewing positions are as close to directly in front of the screen as possible.

In the case of the LG B6, one of the bigger changes comes from the new OLED SE panel. The TV is slightly brighter than its predecessor, but at the same time it handles direct light reflections worse. The reason is a less effective polarizer, so reflections from windows or lamps are less effectively suppressed, and blacks in a bright room can look slightly lifted. LG tried to partially mask this effect with a satin screen coating. It does help to subtly diffuse reflections, but it doesn't eliminate them as effectively as earlier solutions. And in this respect the B series loses the most compared with the previous generation. During the day the screen no longer looks as clean, and strong light sources can clearly reflect on the panel.

That doesn't mean, of course, that the B6 is unsuitable for a bright living room. The higher screen brightness helps cut through ambient light, and during normal viewing the picture remains readable. The problem starts when there's a large window or a strong lamp opposite the TV. In those conditions the B6 doesn't perform at its best. So it's best used in a room where you can at least partially control the light falling directly on the screen.

The Hisense U7S performs well for daytime viewing. In SDR we measured an average of about 664 nits, and depending on the screen content the brightness ranged roughly from 500 to 800 nits. Even with an all-white image it stays above 500 nits, so a sports broadcast or a bright TV program won't suddenly look dim. That's enough headroom for comfortable viewing in most living rooms. The satin finish does a decent job of reducing reflections, but a window opposite the TV will still be visible. In the photo you can clearly see that its reflection can obscure part of the picture, so high brightness alone doesn't solve everything. On the plus side, blacks and colors hold up in daylight and don't become excessively gray. Overall the U7S works well in a bright room, though you should position it to avoid direct window reflections.

Smart TV: webOS

LG B6 runs webOS, LG’s proprietary platform. Its biggest strength remains the way it’s controlled. The included Magic Remote works like a mouse; just move your wrist to move the cursor across the screen and point at the items you want. It may feel unusual at first, but it quickly proves very convenient, especially when typing text, selecting apps, or navigating a complex menu. The remote itself is fairly minimalist and doesn’t offer many traditional buttons, but the cursor control largely makes up for that. On the other hand, if you don’t want to wave your hand to type letters, you can always speak the desired phrase into the remote and the AI voice assistant will suggest appropriate recommendations.

In terms of available apps, it’s hard to fault webOS. You’ll find practically all the major streaming services here, as well as extra features like AirPlay, screen mirroring, and Chromecast. The TV therefore works well with both Apple phones and Android devices. It’s just a pity that the system on the B6 doesn’t run as smoothly as on higher-end models. At times it can respond with a slight delay, and the home screen is heavily loaded with recommendations, tiles, and ads. That doesn’t make webOS unusable, but it could certainly be more organized.

Classic features

By contrast, the traditional TV features perform very well—features many manufacturers are starting to forget. The LG B6 lets you record programs to an attached hard drive or USB storage. The PVR function also supports scheduling, so you can program recordings in advance from the TV guide. This comes in handy when you want to save an episode, a match, or another event broadcast while you’re away. There’s also a clear channel guide and solid support for terrestrial, cable, and satellite TV. For people who still regularly use traditional television, the B6 is therefore a relatively complete device, provided the lack of teletext doesn’t bother you.

Smart TV: VIDAA

VIDAA HOME OS on the Hisense U7S is feature-rich, runs quickly, and doesn’t complicate everyday use. In addition to apps, it supports AirPlay for streaming from Apple devices and Miracast for mirroring a computer display. Voice search in Polish also works, so instead of typing a movie title with the remote you can just say it. You can also connect a keyboard and mouse. In terms of smart features there’s little to complain about, though before buying it’s worth checking the availability of specific apps you use, as it isn’t as extensive as competing systems.

Classic features and the remote

Hisense hasn’t forgotten viewers who watch regular TV. The U7S lets you record over-the-air programs to a USB drive and schedule recordings for later. There’s teletext, the option to listen to audio with the screen off, and support for Bluetooth headphones. Conveniently, headphones can operate at the same time as the TV speakers, so one person, for example a senior, can use them while others still listen normally. The main notable missing feature is picture-in-picture, or PiP.

We weren’t fond of the remote itself. It’s very plastic and looks rather "cheap", but it does its job well. It has a full numeric keypad, plenty of shortcuts, and controls the TV via radio, so you don’t have to point it at the screen. It’s only a shame the buttons aren’t backlit. Hisense reserves more elegant remote versions for higher-end models, such as the U7S Pro.

The LG B6’s built-in player handles most popular video files played from USB without any major problems. The TV also properly supports subtitles and the most common audio formats, though it lacks DTS support. The situation is somewhat worse for photos. The list of supported formats is fairly limited and does not include HEIC, the format in which photos taken with an iPhone are saved by default. Such files therefore need to be converted to JPG beforehand, or you can simply use the AirPlay function.

The USB player in the Hisense U7S handles most common files. It played our H.264 and H.265 material without issues, including high-bitrate 4K recordings and the test Dolby Vision file. SRT and SUB subtitles work, including Polish characters and font color changes. Not everything worked, however. AV1 and H.266/VVC files did not play, nor did ASS and TXT subtitles. Audio is good, from basic MP3s to FLAC 96 kHz/24-bit, though AIFF and DSD are not supported.

Our biggest issues are with photos. Supported formats are extensive: in addition to JPEG and PNG, WebP and TIFF work as well, but HEIC won't open. Resolution handling is also odd. The TV displayed 4, 6, 8, 16 and 32 MP images, but couldn't handle 10, 12 or 24 MP files. So it's not a straightforward size limit. The player is perfectly fine for videos and music, but when showing vacation photos you may find that some files need to be converted beforehand.

In terms of sound, the LG B6 performs very similarly to last year's model. It still uses a 2.0 speaker setup rated at 20 W, which is more than enough for everyday viewing. Dialogue is clear and the sound doesn't sound bad, but there's no sense of space, dynamics, or bass you get from higher-end models. The TV supports the Dolby Atmos spatial audio format, but DTS:X is missing. The biggest problem, however, is not the speakers themselves but the settings. Compared with its predecessor, a large portion of the options for tailoring the sound to your preferences has disappeared. A few preset modes remain, including AI and Standard, but the ability to fine-tune the audio is much more limited than it was a year ago.

The USB player in the Hisense U7S handles most common movies and music well. It supports 4K content, including a Dolby Vision file we tested, and it correctly displays Polish characters in subtitles. It should be sufficient for everyday use with a USB flash drive, although it can have problems with less common formats. Our biggest issue is with photos. The TV handles their resolution rather selectively: it may open a larger photo but refuse to display a smaller one. When browsing a vacation album this can be annoying, because we can't be sure all the photos will display. Some of them will need to be prepared on a computer beforehand.
