LG UA75006LA (VA) vs Samsung S90H (WOLED)

The LG UA7500 with a VA panel has a brightness that hovers around 350 nits, which, by today’s standards, isn't very impressive. It's hard to talk about a true HDR experience here – most content looks more like classic SDR with a slight attempt at highlights enhancement. One advantage is that regardless of the test pattern, the effect remained relatively stable. However, we noticed that in very extreme scenes with a lot of fine detail, the television can slightly dim the image to achieve better black levels, but this comes at the cost of visibility of bright effects. Additionally, it should be noted that the UA7500 is not equipped with any extra technologies for expanding color. It is neither a QLED panel nor a PFS LED, which is why the coverage of the DCI-P3 color palette is only 80%, causing many HDR movies to appear flat and not fully represent the variety of colors.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price class, although it is slightly dimmer compared to the QD-OLED version. The difference is not as pronounced as in last year’s F series, where gaps could reach as much as 500 nits. Here the specs of both panels are very close, and differences in peak brightness are only about 100–150 nits. In small-area measurements, the S90H on the WOLED panel easily reaches levels close to 1500 nits. That headroom lets it portray HDR dynamics phenomenally—specular highlights, reflections or explosions have the right punch, just as the creators intended in the post-production studio. As with most OLED displays, when a very bright scene fills the entire screen, the protection systems that safeguard the panel kick in and brightness naturally falls to around 700 nits. It’s worth stressing that this is still an excellent result on the market, often noticeably better than many Mini LED screens in the same segment.

Color gamut coverage

The biggest difference between the two S90H variants lies in color reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, colors at very high brightness don’t achieve quite the same intensity, and the volume of the wide color gamut is somewhat more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches nearly 99%, which means that in the vast majority of real film scenes both variants will deliver almost identical images. The true gap only appears in rarer, particularly demanding productions that use the ultra-wide BT.2020 gamut. Due to the WOLED panel’s design, coverage of that standard is about 15% lower compared to the S90HAT with a QD-OLED panel, so the brightest, heavily illuminated HDR colors may appear a bit less vivid.

The Filmmaker mode on the LG UA7500 performs better than one might expect from such a budget TV, but let's not get carried away with the praise. The picture is put together quite sensibly and at first glance is not irritating; however, its weaknesses quickly start to show. This is most apparent in scenes with bright points – lamps in the background or reflections of light on the skin are clearly exaggerated. Characters' faces often look unnatural, as if they have been "burned out." Additionally, the default gamma settings brighten even the smallest details, causing the image to lose subtlety in darker areas. Nevertheless, the fact remains that, for its price range, the UA7500 in factory mode provides a decent starting point. However, it's clear that without additional correction, these issues cannot be avoided, which is why – as with other TVs – we decided to check what could be achieved after calibration.

In Filmmaker mode, which we strongly recommend enabling right out of the box, the S90H offers very good factory color tuning. Colors are natural and faithful to the filmmakers' intent, without the intrusive oversaturation found in more aggressive profiles. However, as is usually the case without full calibration, there can be unit-to-unit variation. In our test the white balance lacked a bit of the blue component, causing the image to lean slightly toward warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve ran slightly low, around 2.2, which resulted in a slight boost to shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

We noticed the greatest improvement when calibrating the mode intended for daily SDR content. We managed to smooth the white balance in an acceptable way and tackle the issue of excessive brightening of small elements by the gamma characteristic. As a result, the image gained the consistency and naturalness that were lacking in the factory settings. After such correction, we can confidently state that for daily television content, programs, or materials from YouTube, the LG UA7500 performs really well – especially after professional calibration. The situation is somewhat different for HDR content. Here, the calibration did allow us to tame the white balance and slightly improve brightness management, but the limitations of the design are immediately apparent. The lack of additional filters to widen the color palette means that the most vivid colors appear flat, and the image does not have the intensity we would expect from good HDR. In SDR, the UA7500 performs quite decently, but in HDR – despite corrections – it remains far behind, and this is a characteristic that one must accept when choosing this television.

After full calibration it can safely be said that the S90H in the WOLED version looks almost perfect. In SDR mode color reproduction errors drop to ultra-low levels, and Delta E values very rarely exceed 2. That's a phenomenal result, so if you care about perfectly faithful color reproduction it's definitely worth considering calibration. The calibrated HDR mode also performs very well, in which the white balance was stabilized and earlier deviations eliminated. After professional tuning it's really hard to find anything to criticize, because the TV delivers an image with almost exemplary naturalness and dimensionality. The slightly lower rating in this category compared with the QD-OLED variant is solely due to the previously described saturation limitation in extremely bright scenes; the tuning options and color fidelity themselves are at the highest level.

The LG UA7500 with a VA panel has shown a really good performance in this category. The image scaling from Full HD content or even SD was surprisingly smooth. The picture looked smooth, edges weren't excessively jagged, and the television maintained a significant amount of detail, which meant that even older movies didn't lose their character. It particularly excelled with faces – there were no artificial contours or the "mask" effect, which often occurs in cheaper models. The way the television handled tonal transitions in lower-quality materials is also noteworthy. Thanks to digital processing, colors didn't blend together, and gradients looked natural and smooth. There was no intrusive image smoothing or loss of cinematic grain. This makes the UA7500 great for everyday content – from terrestrial television, through sports, to YouTube, where we often watch materials in various resolutions.

When it comes to reducing posterization, Samsung has kept the same solutions as last year’s models. The dedicated gradient-smoothing function works quite well and can effectively mask unwanted tonal transitions, which can be useful on a WOLED panel that is somewhat prone to banding. However, keep in mind it acts aggressively. This mechanism, aside from removing artifacts, can clean up fine film grain and slightly soften detail. Ultimately it’s a matter of compromise, but if you care about an absolutely faithful reproduction, it’s safer to leave this option off.

There’s also no breakthrough in scaling. The S90H uses the same NQ4 Gen3 processor as its predecessor, so the quality of upscaling was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still hasn’t dealt with the old overscan issue. With some older recordings or archival material the image edges can be slightly cropped. It’s a minor flaw, but it’s a shame the manufacturer still hasn’t eliminated it.

LG UA7500 is a television with a 60 Hz panel, so it’s hard to expect any awe in this category. It’s more of a screen intended for everyday content or an evening movie session rather than for following dynamic sports events or playing action games. It’s clear that the manufacturer directed this model specifically to that group of consumers – and in that regard, it performs correctly. We have the TruMotion function at our disposal, which is a motion smoother. It’s simple, has only one slider, but it can make a noticeable difference. At lower settings, the image appears more raw and cinematic, while at higher values, motion becomes smoother and more pleasing to the eye.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a refresh rate boosted to 165 Hz, though in practice the benefit will be realized mainly by gamers connecting a powerful PC. For movies, TV series, or sports broadcasts, such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, the OLED panel's lightning-fast response time does its job, so motion is clean and the ghosting or smearing seen on LCD screens simply doesn't occur here.

LG UA7500 is a television that can be safely recommended to "casual" gamers. While it does not have a 120 Hz panel or HDMI 2.1 ports, so fully utilizing the potential of modern consoles is out of the question. However, the manufacturer has taken care to include a few extras that can make gaming more enjoyable. Notably, the Game Bar deserves mention – a very nicely designed panel where you can quickly view and change the most important settings. From this panel, we have access to features such as ALLM (automatic switching to game mode) and frame synchronization, which is VRR. The range of VRR is limited – it works from 48 to 60 Hz – but the mere presence of this feature in such an affordable television leaves a positive impression.

Additionally, there is support for HGiG, which is HDR calibration mode for gaming. It sounds good, but based on testing experiences, we already know that with the UA7500, this option doesn't make much sense. The television does not handle HDR very well, so paradoxically we achieved better results with this mode turned off. This is another signal that the UA7500 is more of a screen for occasional gamers who value simplicity and convenience rather than for those looking for full immersion from the latest consoles.

Players should feel at home with the S90H, because in that respect Samsung left few reasons to complain. The TV has four HDMI 2.1 ports, each of which supports VRR, ALLM, and high refresh rates. There's also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG. In last year's models it could cause issues when used with a console, but in the S90H it now works as it should. What sets it apart from the competition is primarily Game Motion Plus. It's a special motion-smoothing mode designed for games, which works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother, while latency remains at a reasonable level. In our measurements it was under 50 ms, so you can still play comfortably. That's important, because on many TVs turning on a similar smoothing mode causes such a large increase in input lag that controls start to feel noticeably sluggish. Samsung has managed to find a good compromise here. There's still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be a far more useful feature.
