LG MRGB85B vs Samsung S85H

LG MRGB85 offers moderate brightness. On test patterns it reaches around 700 nits, which is a decent result in itself. In real movie scenes, however, values are lower and most often fall in the 400 to 600 nits range. Bright, wide shots look best. In scenes with large areas of black the TV noticeably reduces luminance, attempting to keep contrast as high as possible. The HDR effect is therefore visible, but it is far from the level offered by more advanced Mini-LED designs. Particularly in darker parts of films, the limitations of the edge-lit backlight and imprecise local dimming become apparent again.

HDR colours

A much stronger suit of the MRGB85 is its colour. The TV covers around 95% of the DCI-P3 colour space and 74% of BT.2020, so HDR content can look vivid and impressive. Colours are well saturated, and the difference compared with basic LCD TVs is clearly noticeable. It is worth noting, however, that this is not a classic RGB backlight, where each of the three primary colours is generated by a separate diode. Red is produced by a PFS phosphor, which expands the palette and achieves more saturated red tones. This solution performs well for colour reproduction, but it does not change the limitations of the local dimming. The diodes are not driven independently in the way the series name might suggest... so it turns out that Mini RGB is not the same as Mini-LED RGB!

Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 lineup. In the same film scenes last year’s model sat closer to about 700 nits, while the S85H can reach roughly 800 nits. That’s not a change that completely transforms the HDR experience, but the extra headroom is noticeable, especially with point highlights, reflections or stronger special effects. Around 800 nits is a very good result for an entry-level OLED and in most films it’s enough for HDR to have the necessary punch. Bright elements can clearly stand out against perfect blacks, and that contrast is still doing most of the work here. However, you need to remember the typical limitation of OLED technology. When a very bright scene covers a large portion of the screen, brightness can drop to almost half. This is the result of panel protections that limit its output with large bright areas.

Colours

The S85H can deliver very pleasant, saturated colours and in most HDR films it looks really good in that regard. We measured around 95% coverage of DCI-P3, so the palette most commonly used in films is reproduced to a very high degree. Skin tones, greens and stronger reds still have appropriate intensity and under normal viewing it’s hard to have major complaints. Only when you look more broadly at BT.2020 do the limitations of the new WOLED SE panel become apparent. Coverage was about 70%, a bit less than WOLEDs of the previous generation and noticeably less than QD-OLED panels. In films this isn’t a big loss, since most productions rarely use such heavily saturated colours. You’re more likely to notice it in games, where developers more often opt for more intense colours.

We tested the TV in Filmmaker Mode because, of the available presets, it produced the image closest to reference. The out-of-the-box colour reproduction wasn’t perfect, though. The biggest deviations were in the white balance, with too much red and not enough blue in the image, so the overall picture shifted noticeably towards warmer tones. Whites took on a slightly yellowish tint, and skin tones and bright areas didn’t always look natural. It wasn’t a fault that ruined the viewing experience, but in a direct comparison with the same panel after calibration the difference was clearly visible.

To evaluate colours we of course used Filmmaker mode, and in SDR our S85H unit was set very well from the factory. The largest deviation appears in the white balance, where as brightness increases it starts to lose a bit of blue. In practice this means whites and greys have a slightly warmer tint than they should. However, it's not a big fault and during normal viewing it generally isn't very noticeable. Gamma also stays close to the reference value, so the picture is neither overly bright nor unnecessarily dim. The S85H's SDR picture therefore looks really good straight out of the box. A few more imperfections appear in HDR. Here the white balance shifts more with rising brightness, with blue starting to dominate and the red component clearly lacking. This also results in larger errors in some colours. These aren't yet colour errors that completely change the character of the picture, but in direct comparison with the reference the difference is easier to spot. Overall, Filmmaker mode is a very good starting point before professional calibration.

Calibration primarily corrected the white balance and removed the previously noticeable warm cast. After the correction, whites no longer had a yellow tint and colours became more neutral and natural. The biggest improvement was seen in SDR material, where the picture looked even and much closer to the reference. A similar effect was achieved in HDR. After calibration the image became more controlled, although not all of the TV’s limitations could be eliminated. The main issue remained intense reds, which were not always reproduced with sufficient precision. In practice the MRGB85 handles everyday SDR content very well, but in more demanding HDR material its limitations are still clearly visible.

Calibration delivers really good results on the S85H. First and foremost, we were able to set the white balance almost perfectly, which removes the slightly too-warm picture tone previously seen in SDR. Colour reproduction also improves significantly, with most errors falling to very low levels, and in everyday viewing it's hard to find any visible inaccuracies. You can also improve HDR quite a bit, although some issues remain that stem from the TV's inherent characteristics. The S85H doesn't always hold the luminance curve perfectly. The darkest parts are slightly boosted, while, as you approach the panel's limits, you can see small deviations in the brightest highlights. Add to that the limited coverage of the wider BT.2020 colour gamut, which of course cannot be overcome by any calibration. Despite that, the end result is very good, and after calibration the S85H can deliver a really well-tuned, natural image.

Upscaling and digital image processing perform quite well in the LG MRGB85. The Alpha 8 AI 4K Gen7 processor efficiently upscales lower-resolution material, and you can easily turn off overscan regardless of the source. The TV also handles compression artefacts well. The "Smooth Gradation" function can effectively reduce visible banding and tonal unevenness, but it isn't always precise. At higher settings it can also smooth out fine details, such as the texture of materials. A plus is that it doesn't remove film grain. The safest option is the "Low" or "Medium" setting, which offers the best compromise between artefact reduction and preserving detail.

Samsung's S85H uses the same proprietary AI processor, AI NQ4 Gen2, as last year’s S85F, and in terms of digital image processing it performs quite well. Upscaling is one of the model's stronger points. Lower-resolution material is well sharpened, edges look natural and the picture doesn't come across as overly artificial. Just remember a common quirk of Samsung TVs: at very low resolutions you can't completely turn off overscan, so the TV may slightly crop the left edge of the picture. The "noise reduction" function, that is smoothing weaker tonal transitions, also works very well. The processor can effectively remove posterisation and other artefacts visible in lower-quality material. However, be careful with the strength of this function, because Samsung can be fairly aggressive here. When it's activated, along with unwanted artefacts, fine details such as skin or clothing texture also start to disappear.

The LG MRGB85 is fitted with a VA panel with a native 144 Hz refresh rate, so its motion handling is very good. The TV easily handles 120 Hz content from consoles and higher refresh rates when connected to a PC. That matters not only for gaming but also when watching sport, where camera motion is noticeably smoother than on basic 60 Hz panels. There’s also the TruMotion system, which lets you set the level of motion smoothing yourself. You can keep a more cinematic motion or increase smoothness, which works well for live sports and TV programmes. The adjustment range is wide, so you can easily tailor the motion smoothing to your own preferences.

The S85H uses an OLED panel, so it performs brilliantly when it comes to motion blur. Pixels respond almost instantly, so moving objects don't produce the characteristic ghosting seen on some LCD TVs. This is especially noticeable with sport or fast-paced games, where the picture stays very clean even during rapid motion. The panel itself runs at 120 Hz. That's more than enough for movies, TV shows, sport or console gaming. It's a shame Samsung didn't include a higher refresh rate aimed at PC gamers, as more and more TVs now offer 144 or even 165 Hz at 4K. However, that doesn't affect motion handling in films or sport.

There's also the classic motion smoothing feature with two settings: blur reduction and judder reduction. So you can choose whether films should keep their cinematic 24 frames per second, or whether you'd prefer to smooth them a bit. The S85H gives plenty of freedom here, and the interpolation itself works well and, with sensible settings, doesn't generate too many artefacts.

When it comes to gaming, the LG MRGB85 performs by far the best. The manufacturer hasn’t skimped on the kit and has essentially carried over the full suite of features from pricier TVs into this model. You get three HDMI 2.1 ports with full 48 Gb/s bandwidth. Each supports 4K 120 Hz from a console, and when connected to a PC also 4K 144 Hz. So you don’t need to worry which port to plug your console or PC into, as they all offer the same set of capabilities.

On board you’ll also find VRR, AMD FreeSync Premium, NVIDIA G-Sync Compatible, ALLM and HGiG. Dolby Vision Gaming is included too, allowing supported games to use high refresh rates and dynamic HDR simultaneously on Xbox. Rounding it off is Game Optimizer, a handy in-game menu. Without leaving the game you can change the picture profile, brighten shadow detail or check the current frame rate. In terms of gaming features, the MRGB85 therefore offers almost the same as significantly more expensive LG models.

Samsung S85H is very well prepared for gaming, essentially regardless of whether you connect a console or a computer. The manufacturer didn’t skimp on connectors and all four HDMI ports support full HDMI 2.1. That means you can use 4K at 120 Hz, VRR and ALLM without worrying which input to plug your console into. With multiple devices that matters a lot, since you don’t have to choose between a console, a PC or a soundbar connected via eARC. The feature set itself is very complete. The S85H supports VRR, FreeSync and automatic switching to Game Mode, and Samsung also offers its expanded Game Bar, which lets you quickly view the key signal parameters and change settings without leaving the game. The only real omission is Dolby Vision, which will matter mainly for Xbox owners. That’s a typical trait of Samsung TVs. Game Motion Plus performs very well and it’s one of the features that has set Samsung TVs apart for years. It smooths motion in games running at 30 or 60 fps, but does so without as large an increase in input lag as a classic motion interpolator. In practice, for slower-paced games, racing or action titles it can genuinely improve motion perception, especially if you’re sensitive to low frame rates.
