The 55C635 is a 55 inch 4K TV from TCL. It was launched in 2022. It comes with a 10-bit VA panel. It can achieve a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 80 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV doesn't provide a color gamut specification, but don't worry, we have other means to guess that. Considering the TV features a big 55 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 will be Lifelike! Meaning it is capable of producing accurate colors.
Understanding Color Gamut
Color gamut specification of a display indicates the range of colors that it can produce.
A panel with poor color accuracy will produce undersaturated colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB, rec.2020.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
Now, next in the list is Static Contrast.
Understanding the static contrast ratio
A TV with low static contrast ratio will not produce deep blacks and possibly bleed backlight as shown below:The image is an example of another display, it is not this one
The above TV's static contrast is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
Other than black levels, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
This TV is rated with a static contrast ratio of 6000 : 1., enough to achieve deep blacks. The panel comes with local dimming which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, Dolby Vision and HLG (Hybrid Log Gamma).
Coming to brightness, it is can achieve a maximum brightness of 250 nits. The backlight of this TV is powered by Direct LED technology.
If you are planning to use the TV other than watching videos — like as a PC monitor or for gaming purposes, you should take a TV with lowest input lag. For gaming, both the input lag and response time impacts the performance.
Unfortunately, we cannot find the input lag specification for this unit. Now, as this is not a cheap TV from TCL, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which device 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, get a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 300 x 300 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
The width of this TV is 48.27 inches while its height is 30.67 inches. It is 3.15 inches thick. Overall this TV weighs around 13.2 kilograms (including stand). Without stand, it weighs 12.1 Kilograms.
