If you simply must have a huge TV in your living room then this 65-inch 4K set is a great choice. This TV is at its best when displaying 4K HDR content, but, regardless of the definition, motion is expertly handled, with no hint of smear. Big TVs have more space for speakers and often produce a more powerful sound and that’s the case with this TV: it’s punchy and strong, but always balanced.

This TV’s stylish, but wide, base won’t fit on every TV stand, but the quality of the picture and audio means it might be worth getting a new unit. The colour reproduction is particularly impressive and the smart TV system is a doddle to configure and use.

This 55-inch TV is part of LG’s premium line of TVs. It’s still 4K, but as it’s top-of-the-line it should have excellent picture quality. It didn’t disappoint. Motion is smooth and even when the action hots up there’s no loss of detail. The sound is powerful, but there’s a touch too much bass, which can lead to distortion.

This is one of the best 40-inch TVs we’ve tested thanks to its excellent contrast that means whites shine brilliantly and blacks are dark, although we would’ve liked to have seen more detail in the darker scenes. A lack of bass means the audio isn’t quite as good as the picture, but it’s better than many TVs manage.

We found a lot to love in this 40-inch TV. A balanced contrast across standard definition, HD and 4K content is backed up by fluid motion. Sound is good, too, if a little weak compared to some Best Buy TVs.

The prices, scores and recommendations in this table are correct as February 2018.

Top TV features worth paying for

4K ultra-HD TVs cost as little as £500. With four times the number of pixels as Full HD, 4K screens are more detailed so worth spending that little extra money. Full-HD pictures look better on a 4K screen, but 4K content makes full use of the technology. More and more of this is arriving through pay TV and streaming services. Find out more about 4K ultra-HD TV.

Most 4K TVs come with High Dynamic Range (HDR). These give brighter whites, darker blacks and wider gamut of colours. But you need HDR content to see the benefits. It’s not a ‘must have’ yet but, with the BBC running trials into broadcast HDR, it could become a staple in a few years. Find out more about HDR TV.

Organic LEDs, or OLEDs, are found on some high-end TVs and produce dazzling pictures with smooth motion, deep blacks and vibrant colours. We’ve been impressed by their picture quality in the lab, but that’s not to say you should discount traditional LED-backlit TVs. Find out more about OLED TVs.

QLED is the new name for Samsung’s OLED-rivalling quantum-dot TVs that we’ve seen in the past few years. Here, light hits a layer of quantum dots which produce bright, vibrant colours. The three we’ve tested earn Best Buys, but it’s nothing we haven’t seen from some older Samsung sets. Find out more about QLED TVs.

TV brands worth paying for

Four brands dominate the TV market: Samsung, LG, Sony and Panasonic. But some less well-known TVs manufacturers – the likes of Bush, JVC and Celcus – may catch your eye with prices that are difficult to refuse. Is it ever worth punting for one of these smaller brands?

Well, the numbers speak for themselves. Between June 2014 and June 2017, we reviewed 616 TVs from Samsung, LG, Sony and Panasonic. They have a respectable average test score of 64% and 147 of those have been deemed worthy of a Best Buy.

We’ve tested 124 TVs from other brands. But these only manage a lowly 46% average test score, just marginally above the Don’t Buy mark. In fact, 45% have been judged to be Don’t Buys. And the number of Best Buys? Merely one.

Best time to find great TV deals

We see similar trends for TVs every year, with prices steadily declining, interspersed with typically three periods of more severe discounts. All our TV reviews feature graphs like the one above, showing you how the price has changed over time.

Pretty much all of the TVs from Samsung, LG, Sony and Panasonic hit the shelves in the Spring. But frankly, you should never pay full price for a TV. Merely weeks after TVs are released we’ve seen discounts for as much as £700 on these brand new sets. Wait until later in the summer, and prices could be a smidgen lower again.

There are some deals to be had around Black Friday (24 November 2017) and Christmas, but you shouldn’t be blinded by big discounts – our research has shown that not all Black Friday deals are as good as they might seem. A better way to shop is to know what you should expect to pay. All our online reviews show price-tracking data, so you know whether a deal really is as good as it seems.

But the time to strike is when the next generation of TVs launch the following Spring. With manufacturers looking to clear old stock to make way for new, higher-priced models, older TVs have their sticker prices slashed. A savvy shopper in Spring could save as much as 50% picking up one of these now year-old TVs.

Where to buy a bargain TV

It's worth shopping around to find the retailer with the best price. Then, once you know the very lowest it's being sold for, you can decide whether it's worth paying a little bit more for the same TV from a retailer you've tried and trust.

That said, don't be afraid to take the plunge on a retailer you haven't heard of before. Some independent stores can offer great deals both online and on the high street. For instance, if you've chosen a slightly older TV, some independent retailers may have an ex-demo model going cheap. But do your research beforehand, especially when buying online. Search for other customers who have bought products from that website and shared their experiences. You'll find reviews of retailer websites on Trustpilot.

Many major retailers also run price-match schemes. Currys/PC World promises to beat the price you'd pay at AO.com, Argos, Asda, John Lewis and Tesco. John Lewis will match the price of any retailer with a high street shop (so no online-only stores). So long as a product is new and boxed, in stock and offered with a similar guarantee, Richer Sounds will drop their price to a fraction below what's offered elsewhere. While AO.com boldly claims to price match every product against any retailer.

We also give our own seal of approval to a select number of retailers. Look out for a Which? Recommended Provider logo in store or online. Based on overall satisfaction and how likely people are to recommend it to a friend from our annual survey, only the retailers with the best customer scores earn this coveted accolade.
