The 55NANO766QA is a 55 inch 4K TV from LG, launched in the year 2022. It features a 10-bit VA panel. The maximum resolution it can display is 3840 x 2160 @ 60 Hz with a pixel density of 80 ppi.
After screen size and resolution, the next important feature of a display that impacts picture quality is Color Gamut.
This TV doesn't come with a color gamut specification, so we have to take a guess. Considering the TV features a 55 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. The color quality on this TV should be Lifelike! It will produce color accurate images.
Understanding Color Gamut
Color gamut specification of a TV indicates the range of colors that the TV can display.
A display with poor color reproduction will produce undersaturated/washed out colors that will spoil your immersive experience.
Different manufacturers use different units to specify color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it impacts the picture quality the same way.
The importance of 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 image is an example of another display, it is not this one
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.
Other than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
There's no mention of this spec in the TV's official datasheet. Once again we have to take a guess based on the TV's other specifications. For a TV with VA panel, the static contrast ratio will surely atleast be 3000:1 or above So that's a plus.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
As for brightness, the peak brightness the LG 55NANO766QA can achieve is 250 nits. The panel of this TV is powered by Direct LED backlight technology.
If you are planning to use your TV only for content consumption, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to take a TV with the lowest input lag and response time.
Sadly, we cannot find the input lag specification for this unit. Now, since this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the latency at which your device inputs changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that comes with an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 55 inches vertically and 48.62 inches horizontally.
Coming to thickness, it is 2.29 inches thick. It weighs around 14.6 kilograms, another 1.4 kgs including stand.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
Hardware and Audio
The chipset of LG 55NANO766QA is powered by 4-Core CPU. However, LG didn't provide any specification about the RAM on the TV's specsheet.
Speaking of OS, the LG 55NANO766QA runs webOS 22 Operating System.
For display connectivity, there are three HDMI 2.0 ports on this TV.
