The 55QNED806QA is a 55 inch 4K TV from LG. It was launched in 2022. It comes with a True 10-bit VA panel.
The maximum resolution it can display is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 80 ppi.
Picture Quality
Now, the very next specification of a display that impacts picture quality is its Color Gamut.
LG has not provided a color gamut specification for this TV. But don't worry, we have other means to guess that.
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. Undoubtedly The color accuracy on this TV will be Lifelike! Meaning it is capable of producing accurate colors.
What Color Gamut means ?
Color gamut spec of a TV is a measure of the range of colors that it can produce.
A panel with poor color reproduction will produce undersaturated/washed out colors that will spoil the immersion.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 to name a few.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast ratio of a TV holds almost equal role in picture quality.
Understanding the static contrast ratio of a TV
A TV with low static contrast ratio will not produce deep blacks and possibly can bleed backlight as in the images below:
The image is an example of another display, it is not this oneThe above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, 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 in a sense.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 8000:1., well enough to achieve deep blacks. For the record, it also comes with local dimming backlight technology which is a plus.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma) and HDR10.
Coming to brightness, it is capable of producing a maximum brightness of 250 nits. The backlight of this TV is powered by Edge LED (Local Dimming) technology.
Gaming Performance
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 get a TV with the lowest input lag and response time.
Unfortunately, there is no specification for input lag on this TV. But as this is not a cheap TV from LG, 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 key-presses or mouse movements changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, get a TV that features an input lag and response time of < 20ms.
