About the TCL C855K
The TCL C855K is an LED TV range. Verified UK models include 75-inch and 85-inch screen sizes.

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.
