The OLED65C2SW is a 65 inch 4K TV from LG, launched in the year 2022. It comes with a True 10-bit OLED evo panel. It can display a max resolution of 3840 x 2160 @ 120 Hz with a pixel density of 68 ppi.
Picture Quality
Now, the next important specification of a display that defines picture quality is its Color Gamut.
The LG OLED65C2SW features a DCI P3 coverage of 100% — equivalent to 136.36% sRGB coverage. The color quality on this TV should be Lifelike!
What is Color gamut ?
Color gamut spec of a TV is a measure of the range of colors that it can produce.
A panel with poor color accuracy will produce undersaturated colors that will not be pretty to look at.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 to name a few.
As for this TV it is specified using DCI P3.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast of a TV similarly impacts its picture quality.
Understanding the static contrast ratio of a TV
A TV with low static contrast ratio will not produce deep enough blacks and can bleed backlight as in the images below:

The above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
Also note, static contrast ratio and resolution go hand in hand when it comes to details. To put it into perspective, a TV with low contrast ratio will show both dark gray and black as black, 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.
Given this TV comes with an OLED panel, its static constrast will be Infinity : 1. So no need to worry about this at all.
HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10 Pro are also supported on this TV, so that's a plus.
Coming to brightness, it is can achieve a maximum brightness of 850 nits.This amount of brightness is good enough even for a room with sun's rays in!
Gaming Performance
If you are not interested in gaming, you can safely ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.
The input lag on this TV is 5.4 ms and its minimum response time is 0.2 ms. Pick this one if you are a gamer.
Understanding Input lag and response time
This lag is the latency at which device inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that has an input lag and response time of less than 20ms.
