Picture Quality
Now, the next important specification of a display that defines picture quality is its Color Gamut.
Speaking of which, this TV comes with a DCI P3 color gamut coverage of 96% — equivalent to 130.91% sRGB coverage. The color quality on this TV will be Lifelike!
What is Color gamut ?
Color gamut spec of a TV is a measure of the range of colors that the TV can display.
Put Simply, this specification determines the ability of a TV to produce accurate colors. A display with low color 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,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, rec.2020.
For example, the color gamut of this TV is specified in terms of DCI P3.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.
Understanding Static Contrast
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
This defines the intensity of black levels. That is, a TV with static contrast ratio < 1000:1 will produce black images something like this:

Apart from that, such TVs are also prone backlight bleeds that will impact your experience — as shown below.

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, thus lesser detail overall.
This TV comes with a static contrast ratio of 1200 : 1. — good enough for a TV in this range. The panel comes with local dimming backlight technology which is a plus.
HLG (Hybrid Log Gamma), HDR10+, Dolby Vision, Dolby Vision IQ and HDR10 are also supported on this TV, so that's a plus.
Coming to brightness, the peak luminance the TV can produce is 3000 nits with the help of Mini LED backlight. This amount of brightness is good enough even for a well-lit room!
Gaming Performance
If you aren't interested in gaming, you can ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, you should take a TV with the lowest input lag and response time.
The input lag on this TV is 20 ms and its minimum response time is 8 ms. It is acceptable for casual and non-FPS games but is not suitable for competitive or FPS games like COD.
Understanding Input lag and response time
This lag is the amount of time at which your device inputs changes the content of the screen. 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 has an input lag and response time of < 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 57.75 inches and 34.37 inches respectively. It weighs approximately 17.5 kgs.
Now, speaking of ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 300 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
