Top 4K UHD TVs

As 4K TVs now make up the bulk of LG, Panasonic, Sony and Samsung's yearly ranges, the price has come down, with some now available for less than £400. Find out which 4K TVs impressed us most with their picture and sound quality.

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.

This is the best TV in this size bracket. The level of detail is fantastic, and colours look vibrant. It sounds great, too.

When it comes to vibrancy and sheer impact, there are few TVs that can top this 65 incher. It's not just the stunning picture that impresses either; it sounds superb.

Samsung's QLED sets tend to score best, but there are some winners in its LCD lineup, too, and this is one of them.

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.

The lower resolution picture is cold and boring, and it sounds thin, too.

It's a truly dire 50-inch TV with no redeeming qualities.

This brand needs to make a decision. It can either keep releasing terrible TVs that don't cost very much or it can go for superior components, take more time to tweak the screen and picture, and release something half decent. We hope it heads for the latter, but it hasn't in 2019.

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. 

When choosing a 4K TV it's important to consider screen size. You can see what size TV will best suit your room with our TV screen size tool.
