The 50C635 is a 50 inch 4K TV from TCL. It was launched in 2022. It features a 10-bit VA panel. It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 89 ppi.
After screen size and resolution, the very next specification of a display that will impact your viewing experience is Color Gamut.
This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that.
Now, since the TV features a big 50 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. The color accuracy on this TV should be Lifelike! It is capable of producing accurate colors by default.
What Color Gamut means ?
Color gamut spec of a display is the measurement of the range of colors that the display can show.
A display with poor color accuracy will produce washed out colors that will spoil your immersive experience.
Different manufacturers use different units to specify color gamut. Such as — sRGB (most popular), NTSC, DCI P3 Adobe RGB and 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.
Now, after color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
Understanding 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 specification defines the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 may produce black images something like this:
Note that, such TVs may suffer from backlight bleeds that will affect your experience — as shown below.The image is an example of another display, it is not this one
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 is rated with a static contrast ratio of 6000 : 1., good 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+, Dolby Vision and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
Coming to brightness, the peak brightness the TV can produce is 250 nits. The panel of this TV is powered by Direct LED backlight.
If you are planning to use your TV solely for content consumption, you can safely ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, make sure to get a TV with the lowest input lag and response time.
Unfortunately, we cannot find the input lag specification for this unit. But as this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the latency at which your inputs changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, get a TV that has an input lag and response time of less than 20ms.
Ergonomics and Dimensions
