Picture Quality
After screen size and resolution, the very next spec of a display that will impact your viewing experience is Color Gamut.
This TV features 95% DCI P3 color gamut coverage — equivalent to 129.55% sRGB coverage. The color accuracy on this TV will be Lifelike!
What Color Gamut means ?
Color gamut specification of a TV is a measure of the range of colors that the TV can show.
A display with poor color reproduction will produce undersaturated/washed out colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc. It is upto the manufacturer which one they choose.
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.
Now, after color gamut, the static contrast specification of a TV holds almost equal role in picture quality.
What is Static Contrast ?
There are two 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 SC ratio less than 1000:1 may produce black images something like this:

Apart from this, such TVs are likely be prone to backlight bleeds that will impact your experience — as shown below.

Also, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 4000 : 1., good enough to produce deep blacks and eye-catching visuals. The panel comes with local dimming which is a plus.
Dolby Vision, HDR10, HLG (Hybrid Log Gamma) and HDR10+ are also supported on this TV.
As for brightness, it is can produce a maximum luminance of 300 nits, which is powered by Direct LED backlight.
Gaming Performance
If you are planning to use your TV only for content consumption, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to take a TV that features the lowest input lag and response time.
The input lag on the Hisense 50A6GQ is 20 ms and its minimum response time is N/A. It is acceptable for casual and non-FPS games but is not suitable for competitive or FPS games like COD.
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.
Although for better experience, look for a TV that features an input lag and response time of less than 20ms.
