Best 4K TVs Buying Guide: Welcome to TechRadar's round-up of the best 4K TVs you can buy for any budget in 2018.

There has never been a better time to buy a 4K Ultra-HD TV. The technology is better now than it's ever been, and 4K content has become the new norm for streaming services like Netflix and Amazon, as well as Blu-ray discs.

Yes, far from being the niche technology that it was a few years ago, 4K (also known as Ultra HD) is the 4x improvement your TV has been waiting for. 

But making a good 4K TVs isn't just about how many pixels you can push to a screen; it's about the quality of those pixels. To that end, there's even newer technology that we're excited about, like High Dynamic Range and Wide Colour Gamut, that promise to take all those new pixels and make them truly shine.

What you need to know about 4K TVs

Not only do these screens have four times the amount of pixels as their aged (but still-revered) 1080p brethren, but 4K screens also usually pack in screen technology like High Dynamic Range (HDR) and Wide Color Gamut (WCG) that really make those extra pixels shine in all their glory. 

The last reason 4K TVs have taken off is that game consoles, like the PS4 Pro and Xbox One X, have totally embraced the 4K future, as have the Blu-ray industry and streaming video player market. Pretty much everyone is on board the 4K Ultra HD train these days.

After an underwhelming debut, Samsung’s QLED technology really needed to bounce back in style in 2018. It didn't surprise us in the least, then, to discover Samsung threw the kitchen sink in with its new Q9FN QLED Series of TVs. 

As well as being even brighter and more colorful than last year’s equivalent model, Samsung's 2018 flagship screens use a completely different lighting system to combat its predecessor’s contrast problems: Full Array Local Dimming rather than edge-lit LED lighting. The FALD panel works in tandem with Samsung QLED Quantum Dots to produce a picture that's brighter and more colorful than near any we've seen come from the South Korean manufacturer. 

Do those features alone make Samsung Q9FN the best TV on the market? No, but throw in technology like HDR10+ and Q HDR EliteMax – what Samsung bills as its maximum High Dynamic Range experience that’s exclusive to the Q9FN – and there's very little doubt in our mind that this is Samsung's best TV ever.

Short and sweet, the KDL-55XF9005 is a brilliant mid-priced TV. Every one of the improvements Sony has introduced over and above last year’s already excellent XE90 series – better processing, more brightness, slightly more backlight dimming zones, improved motion performance – delivers the goods, resulting in picture quality that humbles many more expensive TVs. 

Its Android TV system and some generally minor backlight clouding stop it short of perfection, but it’s hard to imagine any similarly priced upcoming 65-inch rival getting the better of it.

There's a very good reason that Hollywood video editors master on OLED TVs - they simply outmatch anything else on the market. 

And while LG and Sony certainly have their merits in this area (the former is the largest producer of OLED panels in the entire world, after all), Panasonic is certainly no slouch in this arena. All you need to do is look at the Panasonic FZ952, the latest OLED reference TV from Panasonic, to see why.

The FZ952 is a luscious OLED that puts performance first. Its colour handling is class-leading, and its HDR talents are a match for any of its rivals. In fact, it just might offer the best picture performance that we’ve seen on a 4K OLED to date. 

The FZ952 isn’t the complete package, lacking as it does Dolby Vision and Atmos compatibility, but it wins more arguments than it loses. We suspect you’ll appreciate the easy sophistication of its smart platform, the quality of that low-lag game mode, and the sheer musicality of the Technics soundbar.

The 55A1 – and the A1 OLED series overall – are crowd pleasers in just about every way. Their ‘picture only’ design has been beautifully realized, managing to be simultaneously subtle and dramatic. Their vibrating screen delivers a far more powerful and effective sound performance than I’d thought possible, too. 

The real stars of the show here, though, are the A1’s exquisitely detailed, contrast-rich and colorful pictures. These prove emphatically what we’ve long suspected: More brands using OLED technology can only lead to good things.

 We've long loved LG's B-Series of OLED TVs with last year's B7 OLED as the pinnacle of affordable OLED technology. But this year, LG has delayed the B-Series and has instead made the C-Series its front-running screen.   

While we're a bit miffed at the price increase from last year's B7 to this year's C8, it's hard to say it's unwarranted: LG’s C8 builds on the success of last year’s models, resulting in a TV that can deliver astonishing HD/SDR images and equally impressive 4K/HDR pictures. It’s not as bright as an LCD TV but those deep blacks make a huge difference to the dynamic range of the image. It’s also capable of vibrant and gorgeous colors, not to mention an astounding level of detail with native 4K content.

The WebOS smart platform remains the best available and the choice of streaming services is second to none. Once you add the gorgeous design and a comprehensive set of features, you have one of the most complete TVs that we’ve ever reviewed.

The £2,000 TV market has started to get pretty congested this year, but Philips' OLED  does enough to stand out from the crowd. Its Ambilight system is as fun and appealing as it is unique, while its new P5 picture processing system takes Philips’ picture quality in an interesting and welcome new direction, trading a little of the brand’s customary dynamism for a lovely and immersive naturalism that many AV enthusiasts may find hard to resist.  

Overall, it's both a strong picture performer and unique enough in the way it goes about its picture business to stand as a genuine alternative to similarly priced OLED competitors.

While Samsung’s Q7FN isn't quite the pinnacle of QLED technology - that honor is reserved for the Q9FN - it is a great compromise between price and performance, offering a bright screen, three forms of HDR and incredibly accurate colours for  £1,999 (around AU$3,699).

Ambient Mode adds a design aesthetic sure to please even the keenest of eyes and its low-latency game mode makes it a competent companion for the Xbox One X and PS4 Pro. HDR+ mode helps liven up HD/SDR content and of course 4K/HDR content has an eye-watering sheen when viewed on this set. While the Q7FN isn’t the shining star of the QLED range, it’s still a bright spot in the mid-range.
