After screen size and resolution, the next important spec of a display that impacts picture quality is its Color Gamut.
Speaking of which, this TV is rated with a DCI P3 gamut coverage of 100%, which is equivalent to 136.36% sRGB coverage. The color quality on this TV will be Lifelike!
Understanding Color Gamut
Color gamut specification of a display indicates the range of colors that it can show.
What this means is, it indicates the ability of a display to produce accurate colors. A TV with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
In case of this TV, its color gamut 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.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
What is Static Contrast ratio ?
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that may look dusty as shown in the below image.
As you can imagine, this will affect your experience considerably.
Also, 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, so lesser detail overall.
This TV features a static contrast ratio of 8000:1., enough to display deep blacks. For the record, it also comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 2000.
Coming to brightness, it is can produce a maximum brightness of 250 nits with the help of Mini LED backlight.
Now if you are going to use a TV other than using it as a TV — like as a PC monitor or for gaming purposes, you would want to take a TV that features the lowest input lag. For gaming, both the input lag and response time impacts the performance.
The input lag on this TV is 6.5 ms and its minimum response time is N/A. Gamers gonna love this TV.
Understanding Input lag and response time
This lag is the latency at which key-presses/mouse movements changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that comes with an input lag and response time of less than 20ms.
