Picture Quality
After screen size and resolution, the next important specification to look for in a display is its Color Reproduction (defined by its color gamut specification).
Speaking of which, this TV comes with a DCI P3 coverage of 98%. FYI, this is equivalent to 133.64% sRGB coverage. The color quality on this TV should be Lifelike!
What is Color gamut ?
Color gamut specification of a display is the measurement of the range of colors that the display can show.
Put Simply, this specification determines the ability of a display to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different units to define color gamut. Such as — sRGB (standard RGB), NTSC, DCI P3 etc.
For example, the color gamut of this TV is specified in 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.
Next in the list that will impact your experience is Static Contrast.
Understanding the static contrast ratio of a TV
A TV with low static contrast ratio will not produce deep blacks and can bleed backlight as shown 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.
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 produce less shades of colors, so lesser detail overall.
For a display with OLED panel, its static constrast should be Infinity : 1. So no need to worry about this.
Dolby Vision, HLG (Hybrid Log Gamma) and HDR10 are also supported on this TV.
As for brightness, the peak luminance it can produce is 550 nits.This amount of brightness is good enough even for a well-lit room!
Gaming Performance
If you are planning to use your TV solely for content consumption, you can safely ignore these specifications. But if you are also planning 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 ms and its minimum response time is 1 ms. You will love this TV if you are a gamer.
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.
Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.
