LG MRGB85B vs Samsung OLED S95H (S99H) (QD-OLED)

LG MRGB85 offers moderate brightness. On test patterns it reaches about 700 nits, which by itself is a decent result. In actual movie scenes the values are lower and most often fall between 400 and 600 nits. Bright, expansive shots perform best. In scenes with a lot of black the TV noticeably limits luminance, trying to maintain the highest possible contrast. The HDR effect is therefore visible, but it is far from the level offered by more advanced Mini-LED designs. Especially in darker parts of films the limitations of edge-lit backlighting and imprecise local dimming become noticeable again.

HDR Colors

A much stronger suit of the MRGB85 is its colors. The TV covers about 95% of the DCI-P3 color space and 74% of BT.2020, allowing HDR material to look vivid and striking. Colors are well saturated, and the difference compared with basic LCD TVs is clearly visible. It is worth noting, however, that this is not a classic RGB backlight, where each of the three primary colors is generated by a separate diode. Red is produced by a PFS phosphor, which expands the palette and yields more saturated red shades. This solution works well for color reproduction, but it does not change the limitations of dimming itself. The LEDs 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!

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in movie scenes can exceed 2800 nits! Regardless of the scene, you can count on powerful HDR effects that practically blind you, and that's exactly what we expect from a top-tier screen. It's inherent to OLED panels that in very bright, full-screen shots they won't sustain as high a brightness as they do with small highlights, but the results are still excellent. In a bright scene from the film The Meg, the sun still exceeded 2200 nits. That means the S99H was able to maintain higher brightness than most Mini LED screens on the market. In terms of brightness, the S99H is currently the best OLED TV we've tested.

Color gamut coverage

The S99H also handles color exceptionally well, which is a direct result of the QD-OLED panel used here. Regardless of the test scenario, whether synthetic test patterns or measurements with film material in the background, the results stayed at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the most demanding color space it reaches nearly 90% of BT.2020. That's top-tier performance on the market. These results match what we saw in the new SQD-Mini-LED screens, and in real movie scenes they even outperform RGB Mini LED displays.

We tested the TV in Filmmaker Mode, because among the available settings it produced the image closest to the reference. Factory color reproduction was not perfect. The biggest deviations were in the white balance, with too much red and not enough blue, which pushed the picture noticeably toward warmer tones. Whites took on a slightly yellowish cast, and skin tones and bright areas did not always look natural. It wasn’t a flaw that completely ruined the viewing experience, but in a direct comparison with the same screen after calibration the difference was clearly visible.

Samsung offers a whole host of picture modes and features, but as usual we recommend choosing Filmmaker Mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor shortcomings. This mainly concerns a slight drift in white balance in SDR content and a slightly low gamma. As a result, in a darker room the image can be a bit too bright relative to the reference gamma of 2.4, which is the standard for watching films with the lights off. These are of course small issues, since overall color reproduction remains very good and the errors in ColorChecker measurements are small. However, we know that from a screen of the S99H's class you can and should expect even more, so we had it professionally calibrated.

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

After professional calibration, FILMMAKER mode looks virtually perfect. Because Samsung offers a rich set of advanced calibration features, we were able to tune the colors to an almost perfect level. Most importantly, we were able to even out the white balance and the gamma curve, which resulted in noticeably better contrast and a more natural image dimensionality. With a profile prepared like this, there's really nothing to nitpick or call a flaw. After calibration, the S99H is capable of delivering an essentially reference-quality image.

Upscaling and digital image processing perform quite well on the LG MRGB85. The Alpha 8 AI 4K Gen7 processor efficiently upscales lower-resolution content, and you can easily disable overscan regardless of the source. The TV also handles compression artifacts fairly well. The "Smooth Gradation" feature can effectively reduce visible banding and tonal unevenness, but it doesn't always work precisely. At higher settings it can smooth over fine details, for example material textures. On the plus side, it doesn't remove film grain. It's safest to use the "Low" or "Medium" setting, which provides the best compromise between artifact reduction and detail retention.

The proprietary Samsung NQ4 Gen3 processor handles upscaling and digital image processing. It does a very good job scaling lower-resolution material to 4K. The picture is sharp but doesn't look artificial or overly sharpened. The only fairly specific drawback appears with very old footage shot at 480p or lower. In those cases the TV can slightly crop the edges of the image.

The processor also copes quite well with artifacts visible in low-bitrate material, for example heavily compressed YouTube videos. The noise reduction feature effectively smooths the image and reduces posterization, but it works rather aggressively. It can remove not only unwanted artifacts but also some fine details and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image over keeping every detail, it can be useful.

The LG MRGB85 is equipped with a VA panel with a native 144 Hz refresh rate, so it performs very well in terms of motion smoothness. 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 sports, where camera movement is noticeably smoother than on basic 60 Hz models. 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 sports broadcasts and TV shows. The range of adjustment is wide, so you can easily tailor the motion smoothing to your preferences.

Another major advantage of OLED panels is excellent motion reproduction. Thanks to the pixels' near instant response time, the Samsung S99H practically produces no smearing. Fast-moving objects don't show noticeable halos or trailing artifacts, so the TV performs very well for both watching sports and gaming. One quirk of OLED screens compared with LCDs is how they render low frame rate material. With very slow camera movement the image can appear noticeably more stuttery. This can be quite effectively mitigated using a frame interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, making it easy to find a compromise between smoother motion and preserving the cinematic character of the content.

When it comes to gaming, the LG MRGB85 performs best by far. The manufacturer didn’t skimp on the feature set and essentially brought the full suite of functions from higher-end TVs to this model. You get three HDMI 2.1 ports with full 48 Gbps bandwidth. Each of them supports 4K 120 Hz from consoles, and when connected to a PC also 4K 144 Hz. So you don’t have to worry about which port to plug your console or PC into, since they all offer the same capabilities.

It also includes VRR, AMD FreeSync Premium, NVIDIA G-Sync Compatible, ALLM, and HGiG. Dolby Vision Gaming is present as well, allowing supported games to use high refresh rates and dynamic HDR simultaneously on Xbox. Rounding it out is Game Optimizer, a handy in-game menu for gamers. Without leaving the game you can change the picture profile, brighten shadow details, or check the current frame rate. In terms of gaming features, the MRGB85 therefore offers almost the same as much more expensive LG models.

Samsung S99H is also an excellent TV for gamers. It offers almost every useful feature... well, maybe except the obvious lack of Dolby Vision for Xbox consoles. It's equipped with four fully functional HDMI 2.1 ports with the full 48 Gbps bandwidth. Thanks to that we can easily use frame-rate synchronization VRR and automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and without unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you'll find options to add an on-screen crosshair, enlarge the mini-map, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung's feature: Game Motion Plus. It's Samsung's proprietary motion-smoothing system that uses interpolation to increase smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which is an excellent result compared to the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g., GTA 6 😉) that runs at only 30 frames per second on console, the S99H can display it much more smoothly than competing models.
