If 2014 was the year 4K TVs became mainstream – albeit with sky-high prices and enormous screens – 2015 is the year it becomes a seriously viable option. And a compelling one at that.

The pixel-packing screens – with resolutions of 3840 x 2160, four times that of the 1080p Full HD sets that have been part of the household furniture for the past decade – are out in force in 2015. They are now dominating manufacturers' line-ups in a range of sizes and prices, with curved or flat physiques (or both in the case of some flexible screens).

Back in the early days of 2012, 4K aroused much suspicion... Would it survive? Could it realistically become a mass-market successor to Full HD? Three years on, it’s safe to say 4K TV has probably secured its place in the future of home cinema.

And now is a better time than ever to see what the fuss is about. Here's our round up of the reasons that now might be the time to take the plunge - and, because you never know what's round the corner, a few good reasons that you might want to keep a watching brief.

Fantastic pictures

First and foremost, there’s no denying that 4K takes picture quality to new levels. It’s all in the detail – quite literally.

Delivering eight million pixels instead of a Full HD panel’s two million, Ultra HD TV sets are noticeably more insightful when fed 3840 x 2160 material. You really can see the nitty-gritty details in faces and the textures of objects.

Couple that with the fact sets are making headway in others areas – sharpness, colour, contrast – and the result is an immersive, eye-popping picture. And that's before we mention high dynamic range (HDR)

There’s enough content now (we’ll get to that later) to give 4K TVs a fair trial, and we’re well and truly won over as far as performance goes.

More affordable

4K TVs have never been this affordable. The first generation of 4K sets, which went on sale in 2012, came in the shape of whopping great, and not cheap, screens from the likes of LG, Sony and Toshiba.

More sensible £4000-6000 screens arrived in 2013, with 2014 bringing that down to £2000. And now you don’t have to open your wallet even that wide; 2015 sets are more affordable still – and not just those from cheap Chinese brands, either.

There’s a handful of 4K sets under £1000 (from 43in LGs and Sonys to 55in Polaroid and Finlux sets). Of course, pull-out-all-the-stops flagship ranges from the TV giants remain lavishly priced - but even these rarely exceed the £4000 mark.

And you can always pick up some decent TV deals on last year’s batch – you couldn’t say that last year.

Not just big screens

There aren’t just more 4K TVs out there, but more screen sizes to choose from, too. No longer does buying one mean having to accommodate 55in (or bigger) screens.

40in seems to be the popular starting point this year (both Panasonic and Samsung have sets from around £800), with 43in, 48in and 50in sets closely following. Who’d have thought 4K might make it to the bedroom already?

Whether small screens make the most of the technology is another question, but we'll touch on that later...

4K streaming has arrived

Gone are the days when 4K content was limited to promotional flower and cityscape clips. Or even just a trickle of video streaming. Now we can almost binge-watch 4K. Almost.

Last year saw Netflix paving the way for 4K streaming (first there was House of Cards: Season 2, followed by Breaking Bad and its own Marco Polo series) for those willing to pay £9/month – £2 more than the standard subscription. And Netflix is continually adding to that list, with 4K films and TV series forecast throughout this year and next.

Amazon Prime Instant Video followed suit with a host of TV shows available to £6-per-month-paying Prime subscribers at no additional cost. A catalogue of 26 films and counting is available on a pay-per-view basis. That inventory is on the climb, and the good news for 2015 is that the app no longer features just on Sony sets, but is rolling out across LG’s and Samsung’s line-ups too.

YouTube is also expanding its 4K offering, and many 2015 TV sets will support the Google VP9 hardware decoding required to play it.

More importantly, most (if not all) of this year’s sets will also meet the HEVC (High Efficiency Video Coding)/H.265 compression standard needed to stream 4K content, from Netflix for example. Even last year this wasn’t the case, so those who jumped the gun and bought non-HVEC-compliant sets might be out of luck.

4K broadcasts are coming

Though we’re still some way off getting live 4K TV broadcasts, there are certainly plans afoot.

First, the BBC has said it aims to broadcast 4K as ‘standard’ by 2016, following a comprehensive survey that found 23 per cent of users would benefit from 4K broadcasts right now.

And on the pay TV side, both BT and Sky are rumoured to be preparing to launch 4K set-top boxes before the end of 2015. 

It won't happen overnight and there may not be an instant flood of content, but it's clear that broadcasters think the market is now right to make the first step.

Ultra HD Blu-ray is official

Ultra HD Blu-ray is coming this year. The final specification has been confirmed by the Blu-ray Disc Association and players and discs are set to be revealed at IFA in September to go on sale in time for Christmas (we have already seen a prototype from Panasonic at CES 2015).

And it’s not all about resolution: the discs will support another one of this year’s buzzwords, HDR (high dynamic range) technology, as well as improved colour gamut and bit depth (from 8-bits to 10-bits per channel).

You can sit closer

Go close up to a Full HD set and it will look pixelated; you’ll detect some picture noise (ie. graininess).

Not with a 4K screen; you can watch from any distance – even nose-to-the-screen close – and, provided you're playing 4K content, it will look clean and noise-free. 

Why is this good? Bigger screens in smaller rooms without hurting your eyes, that's why.

Upscaling has improved

We found the first generation of 4K sets didn’t handle high- or standard-definition content very well – a real blow when 4K content was pretty much non-existent and that was all you could watch.

Thankfully, the latest models seem to have addressed this issue, so the questionable quality of EastEnders or your favourite DVDs and Blu-rays is no longer a barrier to buying one.

Choose wisely and your favourite TV shows and movies should look just as good as they would on a Full HD screen, even if the TV makes up three out of every four pixels to fill its real estate.

Shoot your own 4K

If you’ve bought a flagship smartphone (or a high-end camera) in the past year or so, chances are it can film 4K video. So any 4K content gap can be filled... by yourself.

The award-winning Sony Xperia Z3 is one such 4K-toting smartphone.

But...

In truth, not all issues surrounding 4K have been rectified. There's pretty much always something around the corner in the consumer electronics market, but here are a few reasons you might want to hold fire on Ultra HD:

Most content will be HD for some time 

Yes, content is on the up, but in the grand scheme of things, high definition is, and will be for the foreseeable future, the overriding resolution. It will be an age until we see a number of 4K channels on our sets, and as for 4K Blu-rays, no doubt they’ll be expensive and you will need a new player.

Requires high bandwidths

There is also the question of how much bandwidth streaming requires. The UK’s average home broadband speed is less than 20Mbps, but Netflix asks for a minimum of 25Mbps to stream 4K video. There are, however, plans to try to combat this with new compression technology.

Futureproofing could be a headache – and pricey

You don’t need new cables to carry these higher bandwidths, but your TV, Blu-ray player, A/V receiver or soundbar – in other words, every link in the home cinema chain – does need to support HDMI 2.0 and HDCP 2.2 (a copyright protection standard) for them to shake hands with one another. A lot of manufacturers are coming onboard this year, so most new kit should be compliant when it arrives, but those with older AV kit may well require an upgrade.

Too small to see the difference?

If you're in the market for a screen of 42 inches or smaller, there's an argument that 4K resolution is unnecessary. As a result, the vast majority of 4K screens are 50in+ models. Smaller 4K TVs are more common in the new 2015 ranges, so we look forward to finding out whether the benefits justify the premium, just as soon as they make it to our test rooms...

"If you're in the market for

"If you're in the market for a screen of 42 inches or smaller, there's an argument that 4K resolution is unnecessary. "

I seem to remember the same argument being made for full HD vs HD ready. It didn't stop full HD becoming the standard all the way down to 32 inches. It might be unnecessary but it's going to happen anyway. See 3D, curved screens, smart tech (when everyone has another box in their rack that does the same thing better). Then suddenly it is necessary and the lack of it loses it a star at review time because it's not competitive in terms of features. Sigh...

There is still a lot of standard definition TV and DVD out there

The point was made that there is still a lack of  accessible 4K content out there but the TVs are better at upscaling Full HD to 4K than they once were.  However what about upscaling of standard definition and DVD material, of which there still is an awful lot being watched ?              

In my experience the upscaling of these materials is very ropey, to say the least. When you consider that, for an SD signal, the TV has to fill in ( by good guesswork or otherwise) 15 out of every 16 pixels then it is not surprising that it is an ask too much.

When all the content you wish to watch is Full HD or 4K then consider the move to a 4K TV,  until then it may be prudent to stay with Full HD or you may find that a lot of what is available to watch is actually unwatchable due to very poor picture quality.                                                                      

 I have talked with a number of people who didn't realise just how bad some TV channels and DVDs would appear on their new 4K TV but had believed it would deliver the same quality of image that they had seen in the store. They just didn't know that it would be source dependent. Neither the manufacturers nor the vendors are going out of their way to inform customers of this important negative factor.

house of cards 4k

I haven't seen it myself but apparently house of cards 4k is meant to be well ropey, no massive difference over hd. Anyway, I think I will wait a few years before upgrading. Out here in Australia the debate is why the broadcasters transmit at lower bandwidths than the rest of the world which will produce non 4k pictures even when the stations start beaming 4k!

Blu Ray 1080p image quality vs 4K?

When Sony were "selling" us Blu Ray format not so long ago, they told us that Blu Ray was "5 times" the clarity of DVD.........although the truth was that Blu Ray provided "only" twice as many pixels as DVD........and the masses were not convinced that Blu Ray offered a significant increase in image quality over DVD. As the Blu Ray disc market has matured it has become obvious that not all Blu Ray discs are created equal, and that is because the actual image quality is dependent on the quality of the film transfer onto the disc format much more so than the actual increased pixels count.Given that many Blu Ray discs have sub standard tranfers then I don't hold out much hope of 4K discs transfers. As for broadcast tv........well free to view HD content is relatively new (As opposed to pay each month for the privaledge SKY HD content!)...... free broadcast HD is pretty limited to just 5 or 6 channels and some content is 1080i rather than 1080p...........  I'd be very suprised if the free to view broadcasters i.e BBC,ITV & Ch4 will have 4K channels providing full 4 K content within the next 5 years.........just like Blu Ray discs....... we rarely get the full benefits of 1080p............. what hope that Blu Ray and broadcast tv can produce the FULL benefits of 4K anytime soon?

Your statement is untrue

Your statement is untrue klambo. Blu ray supports a maximum resolution of 1920 X 1080 which is 2073600 pixels, which is 6 times more than DVD (720 X 480 = 345600 pixels).
