Rank #1 in Best 75 Inch TV 2026: 10 Large-Screen Sets Ranked, Specs Fact-Checked
TCL 75C6K QD-Mini LED 75 Inch 144Hz Smart TV
Price and rating as shown on Amazon when we collected them. Both change.
The TCL 75C6K-UK is the top pick in this guide to 75-inch TVs. It is a 75-inch QD-Mini LED set listed at £829.00, rated 4.4 out of 5 from 25 ratings, with a 144 Hz refresh rate, a stated peak brightness of 1000 nits and HDR support for Dolby Vision and HDR10+. It also carries an Onkyo 2.1 sound system with Dolby Atmos.
Its spec sheet is where the numbers are worth checking. The 1000-nit peak brightness is exactly the figure the £749 Samsung QEF1 quotes in this guide — £80 less for the same headline number. The TCL's Dolby Vision claim is one its maker can back, unlike the Samsung's, and its refresh rate reads 144 in both of the fields that mention it rather than contradicting itself. Two things on the listing still do not reconcile: the star breakdown under the 4.4 average adds up to 100 ratings while the listing states 25, and the first review shown against the set is written about the 55-inch version of this model, not the 75-inch one. Everything on this page comes from the Amazon listing, not from testing we carried out ourselves.
How those 25 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“After using for 24 hours only, I've been really impressed with the TCL 55C6K-UK QD-Mini LED. For the money, the picture quality is outstanding. The Mini LED panel produces deep blacks, bright highlights and vibrant colours that make films and TV shows look fantastic. It's genuinely hard to find another TV at this price that offers the same level of image quality.I was also pleasantly surprised by the built-in speakers. Let's be realistic – they're still speakers in a slim flat-screen TV – but they sound far better than I expected. Dialogue is clear, there's decent bass, and for everyday viewing I don't feel the need to rush out and buy a soundbar.Google TV is another big plus. It's fast, easy to use, and has all the streaming apps I need. I also love having Filmmaker Mode, which gives movies a much more natural, cinematic look without all the artificial processing.There are only a couple of minor negatives. I really wish TCL had included two USB ports instead of just one, as it's limiting if you use external storage or accessories.Also, something potential wall-mounters should be aware of: the speaker housings on the back protrude slightly. Depending on your wall bracket, you may need to use spacers so the bracket clears them. This isn't a major issue, but it does mean the TV may sit a little further away from the wall than you were expecting.Overall, these are minor complaints on what is otherwise an excellent TV. If you're looking for superb picture quality, surprisingly capable sound, and a great smart TV experience without spending a fortune, I can highly recommend the TCL 55C6K-UK.I will however update this review in 3 months, I see the other 2 reviews are from a free product giveaway but I actually agree with most of the statements, don't be put off by the brand name TCL, I've been a Samsung snob for years and now with this current purchase I'll definitely keep an open mind in future.”
Verified purchase“Wow which we'd bought sooner ... the picture quality is outstanding!!The tiniest detail is mind blowing and watching films is something else now”
