Now, the very next spec of a display that defines picture quality is its Color Gamut.
This TV doesn't provide a color gamut specification, so we have to make an assumption based on its panel type. As this 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 quality on this TV will be Lifelike! It will produce color accurate images by default.
Understanding the Color Gamut Specification
Color gamut specification of a TV indicates the range of colors that the TV can show.
A display with poor color accuracy will produce undersaturated/washed out colors that will not be pretty to look at.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
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 also impacts its picture quality.
What is Static Contrast ratio ?
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Also, such displays are likely to suffer from backlight bleeds such as this:The image is an example of another display, it is not this one
This will affect your experience considerably, especially in a dark room.
Other than black levels, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand.
This TV comes with a static contrast ratio of 8000:1., enough to display deep blacks. The panel comes with local dimming which is a plus.
HDR is also supported on this TV in form of Dolby Vision, Dolby Vision IQ, HDR10, HLG (Hybrid Log Gamma) and HDR10+.
Coming to brightness, it is can produce a peak brightness of 1300 nits. The backlight of this TV is powered by Mini LED technology. This amount of brightness is good enough even for a well-lit room!
Now if you are planning to use a TV other than watching videos — like as a PC monitor or Gaming, you would want to get a TV that features the lowest input lag. For gaming however, both the input lag and response time affects the performance.
Sadly, we cannot find the input lag specification for this unit. But since this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input lag ?
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 features an input lag and response time of < 20ms.
