It can display a maximum resolution of 3840 x 2160 @ 120 Hz with a pixel density of 59 ppi.

Picture Quality

Now, the very next specification of a display that defines picture quality is its Color Gamut.

Speaking of which, this TV is rated with a DCI P3 color space coverage of 100%. Incase you're wondering, this is equivalent to 136.36% sRGB. The color accuracy on this TV should be Lifelike!

What Color Gamut means ?

Color gamut spec of a TV is a measure of the range of colors that the TV can produce.

In other words, it tells 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 measurement standards to specify color gamut. Such as — sRGB, NTSC 1953, DCI P3 to name a few.

For example, the color gamut of this TV is specified in terms of DCI P3.

But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.

Color Gamut Chart

After color gamut, next in the list that will impact your experience is Static Contrast.

What is 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.

Static contrast tells the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 will produce black images something like this:

Example of a disply with low contrast ratio

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

Also, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand.

If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.

This TV features a static contrast ratio of 8000:1., well enough to achieve deep blacks. For the record, it also comes with local dimming which is a plus.

HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 32X are also supported on this TV.

Coming to brightness, it is can produce a maximum luminance of 250 nits. The backlight of this TV is powered by Mini LED technology.

Gaming Performance

Now if you are planning to use the TV other than watching videos — say 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 ms and its minimum response time is N/A. Gamers gonna love this TV.

What is Input Lag and Why it matters ?

This lag is the latency at which your key-presses or mouse movements changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.

For best of both worlds, get a TV that has an input lag and response time of less than 20ms.

Ergonomics and Dimensions

Coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 400 mm. Swivel, Tilt or Pivot features are not supported on this unit.

The TV measures 75 inches vertically and 65.75 inches horizontally.
