LG QNED80A6A (VA) vs LG MRGB85B

Let's now talk about how this television shines. If you are expecting dazzling light effects, we need to temper your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. This is not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamism" offered by flagship products. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another crucial category: colours. This is where PFS technology comes into play, which LG marketers disguise under the name QNED/NanoCell. Thanks to this approach, the television offers a much wider colour palette than classic LCD designs. In our tests, coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even with lower brightness, when watching movies in HDR, colours will be vivid, deep, and appropriately saturated. The image is not washed out but rather juicy, which is a significant advantage in this price range.

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!

It might seem that since the QNED80A is one model, regardless of the version, it should offer the same picture. However, practice shows something completely different. Analyzing the variant with a VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This television, “out of the box,” serves us a picture with a clear dominance of red and a deficiency of blue. Overall, it is very warm, even hot. Many users may describe this as a picture that is “too cinematic,” leaning towards sepia. Additionally, there is the issue of the gamma curve – the television has a tendency to slightly artificially brighten scenes (gamma is too low), causing the picture to lose some depth. The good news is that these are not panel errors, but merely software issues. As always in our tests, we conducted professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

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.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initial, too warm white balance and, most importantly, correct the gamma curve. The television stopped artificially brightening scenes, which gave the image depth. The greatest improvement is noticeable in SDR content, that is, while watching regular television, YouTube, or playing games without HDR. Here the QNED80A shows its class – colour reproduction errors (DeltaE) have dropped below a value of 2. In technical terms, this means that the errors are virtually unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Although we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the television still "interprets" the image in its own way. This stems from the nature of the edge-lit backlight with local dimming and the fact that LG gives the calibrator very little control over this parameter. In short: the television struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is significantly more accurate and pleasant to behold than with factory settings, even if it falls a bit short of studio perfection.

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.

In this category, the QNED80A proves to be a true "dark horse." It is an excellent, affordable television for those who frequently watch lower-quality content – for example, traditional cable TV. The processor used here handles upscaling, that is, enhancing low resolution to native 4K, exceptionally well. The image after processing is natural, smooth, and, most importantly, not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality content. This feature works really effectively, eliminating annoying "banding" of colours under heavy video compression. However, we must remain vigilant. Remember that we are not dealing with a top-tier processor known from flagship OLED models. In more challenging scenes, the system may struggle and introduce minor artefacts or distortions. Nonetheless, it is definitely worth giving this feature a chance, as in most cases the quality improvement is visibly apparent.

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.

We move on to a matter that may be decisive for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This television is equipped with a panel featuring a native refresh rate of 60Hz. There is no denying it – at this price, we expected more as we know that Chinese manufacturers can offer 120Hz screens for a similar price. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strongest aspect of this display. Fortunately, LG has equipped the television with a proven motion smoothing system called TruMotion. It works quite effectively with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: the motion becomes smoother, yet still looks natural, without the artificial "television theatre" 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.

Now that we have established that the QNED80A is a television with a 60Hz panel, we must say it plainly: we will not be playing here at 120 frames per second at any resolution. Does this disqualify the equipment in the eyes of gamers? Not necessarily, especially those "casual" ones. LG has decided to sweeten this technical limitation by packing quite a few useful functions inside. We have support for VRR (variable refresh rate) in the range of 48-60Hz and automatic game mode ALLM, which instantly reduces input lag upon detection of a console. All of this is managed from a very convenient, purple Game Optimizer menu, which has already become LG's hallmark. A big plus goes to the manufacturer for consistency regarding HDR. Although the television does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a moderately bright screen, playing in HDR is clear, and the details in shadows and highlights are accurately reproduced, rather than "cut off".

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.
