Top 4K UHD TVs for 2021
A vast range of models to choose from and plummeting prices means if you're buying a new TV then it might as well be 4K. Ultra-high definition content is becoming more plentiful, thanks largely to Netflix and Amazon Video, and leading manufacturers are putting their most advanced screen technology inside 4K sets.
You don't just see the benefit of improved image processors and wider colour ranges when you're watching 4K. Our tests have found that top-rated 4K TVs are better at displaying HD content than similarly priced HD-only TVs.
Not all 4K TVs are created equal of course. The plethora of TVs on show at your local Currys may look good displaying 4K test footage, but put a standard definition or HD episode of Eastenders on when you get home and you may be left ruing your purchase.
We've picked five outstanding TVs that excel no matter what you're watching.
And here are three TVs to avoid
4K video is supposed to be sharp and crisp, with incredible detail and rich, vibrant colours, but just because a TV can display 4K resolution, doesn't mean it will look good.
If a 4K TV can't even get 4K right, then it's unlikely to be any better if you're watching standard or high-definition video. These TVs have awful picture quality and sound to match.
How to buy the best 4K TV
Picture quality is just one part of our extensive TV test. A TV with a stunning screen is no good if the sound it emits is akin to an upset cat. A Best Buy TV must be the full package, sound quality that's easy on the ear, with well-balanced treble and bass that doesn't drown out conversations or make an explosion sound like a party popper.
We expect more of modern TVs. Now that they have internet connections they open up a world of streaming apps, games and more. These smart menus must be easy to navigate and quick to open or else what should be a useful feature will be a frustration.
How easy a TV is to use should extend to its setup, too, not just navigation around the smart menus and electronic programme guide.
