LG is once again trying to surprise with its lineup of televisions. This year the manufacturer launched a new Mini RGB series, and one of its members is the LG MRGB85. It’s a fairly unusual design, because it uses three-colour RGB backlighting in an edge-lit arrangement rather than the conventional local-dimming backlight. It sounds intriguing, but does such a solution actually translate into better picture quality? We checked that in our review.

LG MRGB85 - Our verdict

6.9

Overall rating

The LG MRGB85 is a television that is best suited to gamers and users who are attached to webOS. In that respect it is hard to fault. It offers plenty of benefits for gamers thanks to a very high panel refresh rate. Add to that the smoothly operating webOS, which stands out above all for the convenient Magic Remote and a full set of features for traditional television. The problem begins when you look at the overall picture quality and compare it with the price the manufacturer is asking for this model. The MRGB85’s launch price is, to say the least, difficult to regard as attractive compared with competing models. For similar money you can find televisions offering much more advanced backlighting and, above all, better black level control. What causes the most controversy, however, is the naming and the way LG positions this model. True, the MRGB85 uses a tri-colour backlight, but it is edge-lit. It is therefore hard to call this a fully fledged RGB Mini-LED in the sense commonly used for TVs that employ a large number of independently controlled zones behind the panel. In practice the limitations of local dimming are very noticeable and they significantly harm the viewing experience in dark scenes. That does not mean the MRGB85 is a bad television. It handles everyday content well, offers decent colours, respectable brightness and a very wide feature set. Picture from a standard SDR source can look really good, and Dolby Vision partly helps to hide weaker brightness handling in HDR. However, it is hard to shake the impression that the biggest problem with this model is not the hardware itself but its price and its overly ambitious positioning in the market. If someone is looking mainly for a gaming TV, values the convenience of webOS and finds it on a large promotion, the MRGB85 can make sense. At its current price, however, it falls behind, because the competition today simply offers more in terms of picture quality.

Stand: Height adjustment

Flat design: No

Accessories: Stand

LG MRGB85 looks modern and gives the impression of a higher-end TV. The screen is framed by narrow graphite bezels, and the styling clearly references the OLED B and C series. The lower part of the housing is thicker because it contains the electronics and the backlight system, while the upper section tapers noticeably. The construction is not as slim as in OLED sets, but overall it still looks neat and contemporary. The central stand with height adjustment is noteworthy. Thanks to it you can easily fit a soundbar beneath the screen without obscuring the lower part of the image. It is worth remembering, however, that depending on the market and the model designation, the TV may also be sold with two conventional feet mounted at the sides.

Visibility of details in the lights:

LG MRGB85 uses a VA panel, so even without additional measures it offers better black levels than models based on IPS or ADS panels. In simpler scenes the image has decent depth and can look quite convincing. The biggest limitation appears, however, when local dimming is enabled. The TV uses an edge-lit backlight positioned at the bottom of the screen. As a result it cannot precisely control the brightness of small parts of the picture. When a single bright element appears on a dark background, an entire vertical band often lights up. This is accompanied by a distinct halo, and even more noticeable is the backlight's behaviour itself. When scenes change, brightness can jump up and down sharply, causing the image to noticeably pulse in a dark room. Local dimming can be turned off completely in the TV menu. Contrast then drops noticeably, but the image becomes much more stable and the frequent flicker of the backlight disappears. In practice some users may therefore willingly give up deeper blacks in favour of a calmer, more predictable picture.

Halo effect and black detail visibility:

The video accurately shows differences in contrast and black levels between TVs, as well as potential issues: halo around bright objects or Mini-LED zone operation visible as brightness jumps.

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!

Review LG MRGB85B section HDR effect quality, scene “Billy Lynn”

The photos show two HDR10 movies. 'Pan' is one of the brightest productions ever made, while 'Billy Lynn' (soldier) has brightness typical of streaming (Netflix, Prime, HBO MAX). Notice the intensity of effects and detail in whites.

In a direct comparison with the reference monitor, the LG MRGB85 performs averagely. The biggest differences are visible in scenes with large amounts of black, where the TV cannot maintain sufficiently high contrast. In such shots the limitations of edge lighting and local dimming become most apparent. Material graded to around 1000 nits looks much better. In those films and series the MRGB85 can retain a good portion of detail in the bright areas and render the scene reasonably well. It struggles more with demanding HDR productions. In very bright shots some details are lost in uniform blotches, so the image clearly departs from the reference. The MRGB85 will do for occasional film and series viewing, but it is not aimed at viewers who expect the most faithful cinematic picture.

HDR luminance chart:

Fortunately the LG MRGB85 supports the dynamic Dolby Vision format. Thanks to scene-by-scene metadata the TV can better adjust how it displays the picture to its capabilities. In our comparison the difference compared with the same material shown in standard HDR10 speaks for itself. Dolby Vision preserved more detail in the bright areas of the picture and better controlled overall scene brightness. This is important, because a large proportion of films and series available on streaming platforms use Dolby Vision. This format often helps the MRGB85 reproduce the image much more faithfully than is the case with ordinary HDR10.

LG MRGB85 - Smoothness of tonal transitions

8.9/10

LG MRGB85 handles tonal transitions quite well. In bright scenes posterization is least noticeable and the TV has no problem separating individual shades. Tonal transitions fare somewhat worse in dark scenes, where posterization, in the most demanding moments transitioning into dark shades of grey, can be more noticeable. However, this is rather typical for most TVs. It is worth adding that similar behaviour can be observed in Dolby Vision mode, where posterization on the MRGB85 is slightly worse than usual.

The match photo shows how the TV smooths weak tonal transitions in low-quality video. The model photo shows how it handles upscaling of SD material.

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.

Review LG MRGB85B Blur and motion smoothness — The photo presents the motion smoothing settings in the tested TV.

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.

Blur (4K@144Hz):

Smoothness alone is only one part of assessing motion. The MRGB85 uses a VA panel, which tends to produce smearing, particularly in darker parts of the image. With fast-moving objects you can notice a faint trail behind them, and this is most visible in transitions between dark shades of grey. This is a typical characteristic of many VA panels and the LG MRGB85 is no exception. Motion looks good in bright scenes, but in darker games or films the sharpness of moving elements can be somewhat weaker. That does not rule the TV out, but people who are particularly sensitive to smearing should bear this in mind.

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.

LG MRGB85 - Input lag

9.7/10

Input lag in the LG MRGB85 is really low. Our measured value was around 10 ms with a 120 Hz signal and about 20 ms at 60 Hz. Importantly, we obtained similar results in Dolby Vision mode as well. They may not be the absolute best figures on the market, but in practice they are more than enough for comfortable, smooth gameplay. The delay is not noticeable and should not be a problem even in fast-paced action games or online titles.

Review LG MRGB85B section Computer compatibility, font readability test — The photo shows the legibility of small fonts. Ideally, lines should be the same thickness on both light and dark text, with minimal pixel gaps.

MRGB85 works very well with PCs. Support for 4K at 144 Hz and compatibility with G-Sync Compatible and FreeSync Premium mean it's not just a gaming screen but also a perfectly capable monitor for work. In terms of text readability, it's simply good. The TV properly supports 4:4:4 chroma, so small fonts and system elements remain sharp. Only when viewed from very close can you spot minor artefacts on the edges of letters, but at a normal distance from a 55" screen or larger it makes no difference at all.

LG MRGB85 - Viewing angles

3.4/10

Brightness drop at an angle of 45 degrees: 71%

Viewing angles on the LG MRGB85 are mediocre. Because it uses a VA panel the image loses colour saturation quite quickly, even when viewed from a slight angle. This is a typical trait of this type of panel — in return for high contrast you get poorer viewing angles. IPS panels work the opposite way: they offer lower contrast but retain colours better when the screen is viewed from the side. In theory the MRGB85 belongs to the family of RGB TVs, which can have better viewing angles than models that use additional QLED filters. Here, however, that does not provide much advantage. The modest number of zones located at the edge of the screen and the way they operate mean that, when viewed from an angle, the image quickly loses quality much like on ordinary LCD panels.

LG MRGB85 - Daytime performance

6.1/10

Panel finish: Satin

Reflection suppression: Decent

Black levels during daytime: Good

LG MRGB85 copes quite well in a bright room. Its average brightness reaches around 500 nits, noticeably above average. That means in a moderately sunlit living room the picture remains clear and doesn’t look dim. The screen coating is less effective and only average at reducing reflections. Direct reflections from windows or lamps can be clearly visible, so it’s best not to place the TV directly opposite large windows or strong light sources.

The LG MRGB85 runs webOS, which is fast, clear and provides access to all the major streaming apps. The menu is smooth and navigating it is straightforward. The TV also performs well with conventional broadcast TV. You’ll find features such as Time Shift, HbbTV and a convenient programme guide. The MRGB85 is therefore suitable both for using Netflix or YouTube and for everyday TV viewing.

Control is handled by a newer version of the Magic Remote. Compared with older models it has been noticeably slimmed down and no longer has a conventional numeric keypad, but it fits better in the hand and is more comfortable for daily use. It still retains the distinctive gyroscope, which lets you control the on-screen cursor by moving your hand. Combined with webOS, this works very well.

The sound in the LG MRGB85 is simply adequate and there’s not much more to say about it. The 2.0 system used here, with a total power of 20 W, performs like most TVs on the market. It lacks pronounced bass and a wider soundstage, although it must be admitted it can get fairly loud. For everyday TV viewing this setup will do. However, those who want fuller, more impressive sound should consider purchasing a soundbar or a home cinema system.
