Bargain TVs usually demand a compromise somewhere — washed-out blacks, a panel that smears in fast scenes, or sound that begs for an external speaker. The TCL C6KS refuses to play along, and that’s exactly why it walked away with the best budget 48-50in TV trophy at the 2025 What Hi-Fi? Awards.
At its heart is a QD Mini-LED panel — quantum dots paired with a Mini LED backlight — pushing 4K UHD resolution across a VA panel. That combination is what lets the C6KS deliver punchy, saturated colour (TCL quotes 93% DCI-P3 coverage) and genuinely deep blacks, thanks to local dimming. The number of dimming zones scales with screen size, running from 160 zones on the 50-inch model up to 312 zones on the 75-inch. More zones mean tighter control over contrast and less of the haloing that plagues cheaper backlit sets.
HDR support is comprehensive for the money. You get Dolby Vision IQ, HDR10+ and HLG, so whatever streaming service or disc you throw at it, the C6KS will tone-map intelligently rather than crushing highlights into oblivion.
The audio story is unusually generous too. Rather than the bare stereo pairing most budget sets ship with, TCL fitted a 2.1-channel setup with a dedicated low-frequency channel, backed by Dolby Atmos and DTS Virtual:X. It won’t replace a soundbar for cinephiles, but it means the TV isn’t an embarrassment straight out of the box.
The one place where the budget pricing shows its hand is motion: this is a native 60Hz panel. Serious gamers chasing high frame rates will want to look further up the range, but for movies, streaming and casual play, 60Hz is perfectly serviceable.
What really makes the C6KS compelling is the price, which has been cut. Here’s how the lineup stands across screen sizes:
- 50-inch (50C6KS-UK) — £389
- 55-inch — £419
- 65-inch — £549
- 75-inch — £710
Those are remarkable figures for a Mini-LED set with quantum dots, local dimming and a full HDR roster. A 65-inch QD Mini-LED for £549, or a 75-incher for £710, is the kind of value proposition that simply didn’t exist a couple of years ago.
As a 2025 model year set, the C6KS is on sale now in the UK. If you want the best picture-per-pound on the market and aren’t fussed about ultra-high refresh rates, this is the budget TV to beat — and the only one we’d recommend without hesitation.
