Samsung QLED Q80D vs LG MRGB85B

In the context of HDR, the Samsung Q80D television achieves very positive brightness results in the tested film scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing the user to experience a great juiciness of the image. Such results allow the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g. test pattern 4 from the film Sicario 2), a noticeable drop in brightness can be observed, caused by the large sizes of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements against a dark background. At that point, we may perceive an unwanted lack of brightness, and the HDR effect resembles that of SDR.

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!

In "Filmmaker" mode, which is the best choice out of the box, the Samsung Q80D TV shows solid colour reproduction. For SDR content, a visible drop at the beginning of the gamma curve suggests that details in dark scenes may be less pronounced, impacting the overall viewing experience. Regarding white balance in SDR content, while it is generally accurate, significant drops in blue colour when screen coverage exceeds 70% can result in less natural hues in bright and dark scenes. Users may notice that some blue elements in the image may appear less intense, and the overall colour will have a warmer tint.

In contrast, for HDR content, the EOTF curve being above the reference line for most of the time indicates that the TV may struggle with accurately reproducing brightness and details in the brighter areas of the image, which may be disadvantageous for the viewer. It is also worth noting the substantial drop at the beginning of this graph, indicating that the TV has difficulties reproducing brightness in the darker areas of the image, as seen in the contrast and black tests, where several scenes were unable to showcase the full capabilities of the TV's brightness. In terms of its white balance, the initially good results on the graph are promising, but the sharp drop in red colour, which significantly falls down, combined with a large increase in blue colour, may lead to inaccuracies in reproducing certain skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

We tested the TV in Filmmaker Mode, because among the available settings it offered the image closest to the reference. However, the out-of-the-box colour reproduction was not perfect. The largest deviations concerned the white balance, with the image showing too much red and not enough blue, which caused the whole picture to shift noticeably towards warmer tones. Whites took on a slightly yellowish tint, and skin tones and bright parts of the image did not always look natural. It was not a fault that completely ruined the viewing experience, but in direct comparison with the same screen after calibration the difference was readily apparent.

The film mode after calibration looks significantly better than the one you can see when taken out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Colour Management System). Both in HDR and SDR mode, the white balance has improved significantly, although there are minor errors at the end of the graph in the case of HDR content. The contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve in the television seems to be at an ideal level at first glance. Yet, when we delve deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. One could even say that the television is "cheating" when playing film materials. Such a situation, where the EOTF curve is above the reference line, makes the screen – although it may seem brighter, which some users may find attractive – lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

Calibration primarily allowed us to correct the white balance and remove the previously noticeable warm tint. After adjustment the whites stopped leaning towards a yellow cast and the colours became more neutral and natural. The biggest improvement was seen in SDR material, where the picture looked even and much closer to reference. A similar effect was achieved in HDR. After calibration the image became more organised, although not all of the TV's limitations could be eliminated. The greatest reservations still concerned intense reds, which were not always reproduced with sufficient precision. In practice the MRGB85 handles everyday SDR content very well, whereas in more demanding HDR material its limitations remain clearly visible.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle grading, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes elements that should not be smoothed, such as film grain, to become blurred. For those who value a pliable, smoothed image more, this can be seen as a significant advantage, especially for lower-quality content.

When it comes to image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing viewing comfort. The television handles the conversion of lower-resolution materials well, improving their quality and detail. For example, in the attached image with the model, there are no visible artifacts or excessive fraying of branches, which attests to the advanced image processing technology.

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 regardless of source you can also easily disable overscan. The TV also copes well with compression artefacts. The "Smooth Gradation" feature can effectively reduce visible banding and tonal unevenness, but it is not always precise. At higher settings it can also smooth out fine details, for example surface textures. On the plus side, it does not remove film grain. It's safest to use the "Low" or "Medium" setting, which gives the best compromise between artefact reduction and preserving detail.

The Samsung Q80D television stands out very positively in terms of motion fluidity and motion blur reduction, primarily due to the applied 120Hz panel and above-average response time of the panel. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustment of smoothness on a 10-point scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of rapidly moving objects. In the UFO test, no motion blur is visible behind the moving object, and the image is not cloned forward, indicating a lack of overshoot effect.

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 handling. 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 movement is noticeably smoother than on basic models with 60 Hz panels. We also have TruMotion, which lets you set the level of motion smoothing yourself. You can keep a more cinematic feel to motion or increase smoothness, which works well for sports broadcasts and TV programmes. The adjustment range is wide, so you can easily tailor the smoothing to your own preferences.

The Samsung Q80D television is a true gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz in 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The television also supports HGIG (HDR Gaming Interest Group), enabling optimal display of HDR content in games. Additionally, it is equipped with a Game Bar that allows quick access to gaming settings. Users of Nvidia graphics cards will also be pleased thanks to the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision mode, which may be disappointing for users looking for this HDR format. It is also worth mentioning that since 2022, thanks to a partnership with Microsoft, Samsung televisions offer the Xbox Game Pass application, allowing for cloud gaming. This is an additional advantage for gamers who want to access a wide library of games without the need for a console.

When it comes to gaming, the LG MRGB85 performs by far the best. The manufacturer didn't skimp on features and has essentially brought the full suite of functions from pricier TVs to this model. You get three HDMI 2.1 ports with the full 48 Gbit/s bandwidth. Each supports 4K at 120 Hz from a console, and when connected to a PC also 4K at 144 Hz. So you don't need to worry which port to plug your console or PC into, because they all offer the same capabilities. Also on board are VRR, AMD FreeSync Premium, NVIDIA G-Sync Compatible, ALLM and HGiG. There's also Dolby Vision Gaming, which means in supported games you can use high refresh rates and dynamic HDR simultaneously on Xbox. The package is rounded off by 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.
