Picture Quality

After screen size and resolution, the very next specification of a display that impacts picture quality is its Color Gamut.

This TV comes with a DCI P3 color profile 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 display indicates the range of colors that it can show.

A TV with poor color reproduction will produce washed out colors that will spoil your immersive experience.

It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.

As for this TV its color gamut is specified in DCI P3.

But don't worry, here is a chart that will help you choosing a TV with good color accuracy.

Color Gamut Chart

Other than color accuracy, you should look at the static contrast specification as it impacts the picture quality substantially.

Understanding Static Contrast

Static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such TVs often suffer from backlight bleeds such as this:

Needless to say, this will affect your experience, especially in a dark room.

Note that, 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, thus lesser detail overall.

This TV comes with a static contrast ratio of 8000:1., well enough to display deep blacks and eye-catching visuals. For the record, it also comes with local dimming technology which is a plus.

HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 32X are also supported on this TV, so that's a plus.

As for brightness, it is capable of producing a peak brightness of 250 nits. The panel of this TV is powered by Mini LED backlight technology.

Gaming Performance

If you aren't into gaming, you can ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, you should take a TV that features the lowest input lag and response time.

The input lag on this TV is 6 ms and its minimum response time is N/A. Gamers will love this TV.

What is Input Lag and Why it matters ?

This lag is the amount of time at which your inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.

For best of both worlds, get a TV that features an input lag and response time of < 20ms.
