About the TCL C825K
The TCL C825K is a QLED TV range. Verified UK models include 55-inch and 65-inch screen sizes.
The display resolution is 3840 x 2160 pixels. The backlight specification is: Mini LED (65-inch option). This detail is not supplied for every model option. HDR support includes High Dynamic Range 10 (HDR10), High Dynamic Range 10+ (HDR10 Plus), Hybrid Log-Gamma (HLG). This 4K UHD pixel count is four times that of Full HD, providing the resolution needed to display compatible 4K programmes, films and games in their original pixel dimensions.
The specified refresh rate is 60 Hz. Smart TV features run on Android TV. The number of HDMI inputs is 3. A 60Hz refresh specification corresponds to 60 display updates per second. It is separate from the response time and input lag measured in a review. The HDMI inputs allow separate source devices to stay connected, such as a games console, set-top box and streaming player. Check the individual port specifications for features such as eARC and high-refresh-rate gaming.
The number of USB 2.0 ports is 1. Wi-Fi support is recorded as Yes. Bluetooth support is recorded as Yes.

How the COR Score works
We convert each critic rating to a five-point scale and calculate an equally weighted average. Each publisher counts once: 8/10 becomes 4.0/5, for example. The average is rounded to one decimal place.
Scores based on fewer than three critics are provisional. Products without a usable rating stay unrated. Reviews are grouped by model family; a family score is not a separate test of every screen size.
