Picture Quality
After screen size and resolution, the very next specification of a display that impacts picture quality is its Color Gamut.
The Hisense 75A6GQ is rated with a 95% DCI P3 color gamut coverage, which is 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 display can display.
A TV with poor color accuracy will produce washed out colors that will not be pretty to look at.
Different manufacturers use different units to define color gamut. Viz — sRGB (most popular), NTSC, DCI P3 etc.
In case of this TV, it is specified using DCI P3.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
Why its important?
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that may look dusty as shown in below image.

As you can see, this will impact your experience considerably.
Also note, 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 features a static contrast ratio of 1200 : 1. — good enough for a TV in this range. For the record, it also comes with local dimming feature which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10, HLG (Hybrid Log Gamma) and HDR10+.
As for brightness, it is capable of producing a peak luminance of 350 nits. The backlight used on the panel is Direct LED.
Gaming Performance
If you are planning to use your TV only for content consumption, you can 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 take a TV with the lowest input lag and response time.
The input lag on this TV 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 gameslike CSGO.
What is Input Lag and Why it matters ?
This lag is the amount of time at which inputs changes the content of the TV. 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 less than 20ms.
