Our take on the TCL 55 55C6K Pro UHD MiniLED GoogleTV 144Hz

It runs Google TV with Chromecast built in, plus Wi-Fi, Ethernet and Bluetooth, and supports HDR and the main broadcast tuners. The Mini LED backlight and high refresh rate put it above standard LED sets at this size, and it suits gamers and movie watchers who want bright HDR without stepping up to a flagship.

Questions and answers
- Is the TCL C6K Pro good for gaming?
- Yes. The 144Hz panel and 5.7 ms response time suit fast console and PC games. Check that your console or GPU can drive 4K at high refresh over HDMI.
- How bright is the TCL C6K Pro?
- TCL rates it at 1000 cd/m² peak brightness with the QD-Mini LED backlight. That is bright enough for HDR highlights and daytime viewing in a lit room.
- Does the TCL C6K Pro run Google TV?
- Yes. It is a Google TV set with Chromecast built in, plus Wi-Fi, Ethernet and Bluetooth for streaming and casting.
- What is the difference between QD-Mini LED and regular LED?
- Mini LED uses many small LEDs in zones behind the panel, so it can dim dark areas and push bright highlights harder than edge-lit LED. QD adds a quantum dot layer for wider color.
- Can I wall-mount the TCL C6K Pro?
- Yes. It uses a VESA 300 x 300 mm mount pattern, so pick a bracket rated for a 55-inch TV.
