Frequently asked questions
Is the TCL 50C6K-UK a Mini LED or an OLED TV?
It is a QD-Mini LED LCD TV. Quantum dots provide colour, while a Mini LED backlight with local dimming illuminates the screen. It does not use self-emissive OLED pixels.
Does the TCL 50C6K-UK support 144Hz gaming?
It supports up to 144Hz with a compatible source. The refresh rate available depends on the connected device, signal and settings. A higher game-accelerator figure should not be interpreted as 4K at that refresh rate.
Does the 50-inch C6K have a built-in subwoofer?
The 50-inch model is specified with 2.0-channel stereo speakers producing 30W in total. Do not assume that the 2.1-channel audio advertised for other C6K sizes applies to this model. A compatible soundbar can connect through HDMI eARC.
How many HDMI ports does the TCL 50C6K-UK have?
It has four HDMI inputs, plus one USB-A port, Ethernet and an optical digital audio output. HDMI eARC allows connection to a compatible soundbar or AV receiver.
Which HDR formats does the TCL 50C6K-UK support?
UK specifications list Dolby Vision IQ, Dolby Vision, HDR10+, HDR10 and HLG. The format used depends on the programme, app or connected source.
Does the 50C6K-UK have 512 local-dimming zones?
The C6K range advertises up to 512 zones, but TCL identifies that figure with the 98-inch model. An exact verified zone count for the UK 50-inch version is not established here, so the larger-model figure should not be applied to it.
