The 86QNED85UQA is a 86 inch 4K TV from LG, launched in the year 2022. It features a True 10-bit IPS panel.
The maximum resolution it can display is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 51 ppi.
Picture Quality
After screen size and resolution, the very next specification of a display that impacts picture quality is Color Gamut.
This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type.
As this TV features a 86 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. Undoubtedly The color accuracy on this TV should be Lifelike! It will produce accurate colors out of the box.
Understanding the Color Gamut Specification
Color gamut specification of a TV is the measurement of the range of colors that the display can show.
A display with poor color accuracy will produce undersaturated colors that will spoil the immersion.
Different manufacturers use different measurement standards to define color gamut. Such as — sRGB, NTSC 1953, DCI P3 etc.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Now, after color gamut, you should look at the static contrast specification as it influences the picture quality the same way.
What is Static Contrast ratio ?
A TV with low static contrast ratio will not produce deep enough blacks and possibly bleed backlight as in the images below:

The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More is better.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV is rated with a static contrast ratio of 8000:1., enough to achieve deep blacks. For the record, it also comes with local dimming feature which is a plus.
Dolby Vision, HDR10 Pro, HLG (Hybrid Log Gamma) and Dolby Vision IQ are also supported on this TV.
Coming to brightness, the peak brightness it can achieve is 250 nits. The backlight of this TV is powered by Mini LED technology.
Gaming Performance
If you are not interested in gaming, you can safely ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, make sure to take a TV that features the lowest input lag and response time.
Sadly, we cannot find the input lag specification for this unit. Now, as this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your device inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, get a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
The TV measures 86 inches vertically and 75.79 inches horizontally. In terms of thickness, it is 1.81 inches thick.
In total this TV weighs around 57.5 KGs including stand. Without stand, it weighs 56.6 Kgs.
