Picture Quality
After screen size and resolution, the next important specification of a display that impacts picture quality is Color Gamut.
TCL has not provided a color gamut rating for this TV. But don't worry, we have other means to guess that.
As this TV features a 65 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! It is capable of producing accurate colors AS IT IS intended.
What is Color gamut ?
Color gamut spec of a TV is the measurement of the range of colors that the TV can display.
What this means is, it indicates the ability of a display to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 Adobe RGB, rec.2020.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, next in the list of important specifications 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. Dynamic doesn't matter much.
This defines the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 will produce black images something like this:

Moreover, such TVs may suffer from backlight bleeds that will rob your experience — as shown below.

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 show both dark gray and black as black, so lesser detail overall.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV is rated with a static contrast ratio of 8000:1., good enough to display deep blacks. The panel comes with local dimming feature which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, Dolby Vision, HLG (Hybrid Log Gamma) and Dolby Vision IQ.
As for brightness, the peak brightness the TCL 65C735 can produce is 250 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are planning to use your TV just for content consumption, you can ignore these specs. But if you are also going to use the TV for playing games or use it as a PC monitor, you should get a TV that features the lowest input lag and response time.
The input lag on this TV is 15 ms and its minimum response time is 8 ms. It is acceptable 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 inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that comes with an input lag and response time of less than 20ms.
