Affordable 4K TV equipped with a 55-inch diagonal QLED LCD panel. So-called quantum dots make it possible to achieve a significant increase in brightness and color saturation while simultaneously improving the quality of color reproduction. Also, the TV screen now supports the correct display of HDR content (in particular, HLG, HDR10+ and Dolby Vision formats). To complete the picture, the display lacks only a local dimming system, but it was left to the older models of the series (starting with the C745).
The TCL 55C645 runs the Google TV operating system - recommendations based on previous views are displayed directly on the home page, the system provides a built-in Chromecast and implements voice control through the Google Assistant. A separate line on the TV indicates the game mode. When connecting the console via HDMI 2.1 ports, VRR (Variable Refresh Rate) and ALLM (Automatic Low Latency Mode) optimization technologies are kindly provided to the user. The standard refresh rate for the panel is stated at up to 60 Hz, but for games the Game Accelerator 120 Hz is used. The model's audio system consists of two down-firing speakers with a total power of 20 W with support for Dolby Atmos and DTS.
