The 75C735 is a 75 inch 4K TV from TCL, launched in the year 2022. It features a 10-bit VA panel.
It can display a max resolution of 3840 x 2160 @ 144 Hz with a pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the next important specification of a display that defines picture quality is Color Gamut.
This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that.
Considering the TV features a big 75 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 should be Lifelike! Meaning it is capable of producing color accurate images AS IT IS intended.
Understanding the Color Gamut Specification
Color gamut specification of a TV is a measure of the range of colors that the TV can display.
Meaning, it tells the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
Different manufacturers use different units to define color gamut. Such as — sRGB (standard RGB), NTSC 1953, DCI P3 to name a few.
But you don't need to worry about that, below 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.
Understanding the static contrast ratio
A TV with low static contrast ratio will not produce deep enough blacks and possibly can bleed backlight as shown in the below image:

The above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More the better.
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, so lesser detail overall.
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 8000:1., good enough to produce deep blacks and eye-catching visuals. The panel comes with local dimming which is a plus.
HDR10, HDR10+, Dolby Vision, HLG (Hybrid Log Gamma) and Dolby Vision IQ are also supported on this TV.
As for brightness, it is can achieve a maximum luminance of 250 nits. The backlight used on the panel is Direct LED.
Gaming Performance
Now if you are going to use a TV other than using it as a TV — say as a PC monitor or for gaming purposes, you would want to take a TV with lowest input lag. For gaming however, both the input lag and response time impacts the performance.
The input lag on this TV is 15 ms and its minimum response time is 8 ms. It is good enough for both casual and competitive/FPS games alike.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your inputs changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that has an input lag and response time of less than 20ms.
