The development of television to 4K has picked up speed over the last 12 months and many of the sets you now see on sale include this latest step in television technology. But what exactly is 4K?

4K refers to a resolution of 3,840 x 2,160 pixels. That’s four times the 1,920 x 1,080 pixels found in your full HD TV. We’re looking at about 8.3 million pixels. Cramming so many pixels into a TV means a higher pixel density, and you should have a clearer, better defined picture. It’s not about sharpness, it’s about letting you see more detail and texture.

Alongside 4K is another technology, HDR. This stands for high dynamic range and means the screen can show detail in dark shadows and bright skies at the same time. It leads to striking images. Most 4K TVs now are HDR-capable. There are different HDR standards, be warned. Everybody has HDR10, some other TVs also manage HLG, Dolby Vision and Technicolor. The more your TV supports, the better, generally speaking.

But as with much technology the change is hard to read and complicated by no small amount of marketing hyperbole. While innovations such as 3D television have failed to take off, manufacturers are now widely adopting 4K, leaving many asking if it is time for an upgrade.

4 Rules For Buying a 4K TV!

Is there any difference between 4K and Ultra HD?

4K is by far more commonly used, but you’ll also find people calling it Ultra HD, or UHD. For the average consumer buying a TV, these are one and the same. But there is technically a difference.

In its correct usage, the term 4K refers to a resolution of 4096 x 2160, which was first introduced in digital cinemas. UHD refers to a resolution of 3840 x 2160, which is what you get on the 16:9 ratio TVs you actually take home.

Simply put, 4K TVs have four times as many pixels as 1920 x 1080 (or 1080p) HD TVs, or around eight million pixels in total. What 4K offers is an exceptionally crisp picture, more detailed than standard HD, that can be blown up onto much larger screens.

Types of 4K TV

There are two kinds of 4K TV available: OLED and LED LCD. OLED (organic light emitting diode) means each individual pixel is separately lit, so the screens are much better at contrast than LCD. There’s an LED variant from Samsung called QLED. These are essentially different versions of the same technology, abetted by filters and something called quantum dots to add to the picture quality.

OLED is not as bright as LED and is much pricier to boot, but it’s probably the best picture quality you can currently buy.

How much does it cost?

Things have changed in the last two years and you no longer need to drop thousands of pounds for your first 4K set. Still, many smaller 4K TVs are considered not worth the price tag. If a small screen is what you want, it's probably not worth paying more than £500 for anything less than a 43 inch screen. For the best results in 4K, you will need a screen size of around 50 inches or better, unless you want to sit very close to the screen. For just under £1,000 you can get a quality mid-range 50 inch model with HDR.

Then there is a high upper limit, or lack of one. A 4K TV may cost in the region of £1,500 to £2,000 for the highest quality, while anything more expensive than that is likely a luxury model with an OLED or QLED display and impressive screen size.

What you can watch in 4K TV

Many 4K TVs have apps for Netflix, YouTube and Amazon built in, so you don’t even need the streaming box, though you do need a decent speed in your broadband connection – 15mbps is an absolute minimum, faster is preferable. On Netflix, there are now more than 100 titles in 4K while Amazon Prime Instant Video has been supporting 4K films and series since 2015. For Netflix you will also need to spend a little more to watch 4K with its Premium service.

Meanwhile broadcasters have only been very slowly catching up, with some limited adoption from Sky and BT in the UK. BT introduced BT Sport 4K UHD in August last year, with Sky quickly following suit with the launch of Sky Q. For gaming, 4K has been available for those using PCs for some time, but 4K now has support from the PS4 Pro and is set to be supported by Microsoft's Xbox One X.

Sky Q Silver box and Sky Q service, has also added 4K content since launch. You can watch many films and TV shows in 4K, while most Premier League football games are broadcast in 4K now.

Do I need 4K?

Until very recently there were few programs or films that were even 4K ready, with a trickle of videos on Netflix, Amazon Prime and YouTube supporting the format. So while you may want the best resolution for your TV, you may be limited on the number of shows you can watch right now.

That said, 4K is certainly the direction of travel for top range TVs. If you want the best viewing experience or a large TV of 50 inches or more it is time to settle on a 4K.

And nearly all 4K TVs have the ability to 'upscale' standard HD content. Essentially this involves touching up the image to make it appear higher quality on the 4K display, due to the fact 4K has four times the pixels of normal HD. More expensive 4K TVs are likely to be better at upscaling than some cheaper models.

Is it actually good?

A comparison of resolution and picture quality between a standard HDTV picture and the newest 4K

The extra resolution of 4K images adds better definition and clarity to the picture. The result is images that look incredibly life-like, more like looking through a window than watching TV.

4K is especially effective on very large screens – so ideally you’ll go for a 65-inch set or even bigger. That said, we’d argue that 4K resolution clearly improves picture quality at pretty much any screen size. The effect is more noticeable if you’re moving to 4K from a TV of the same size. Let’s say you have a 50-inch HD TV and you upgrade to 4K: you are cramming four times the number of pixels into the same amount of space. That makes for a noticeably denser picture with finer detail.

To get the best from 4K, it is recommended that you sit closer to your screen than you would with with HD TVs. The extra resolution and increased pixel density means you can sit further forward without spotting individual pixels. And filling up more of your field of view makes for a more immersive experience.

How much internet speed do I need?

This could be the kicker of whether you should be upgrading to a 4K TV. The national average was around 29mbps (megabits per second) in 2016, but in many areas this can be significantly lower. Netflix recommends a minimum of 25mbps to stream 4K UHD titles, so in some cases you may be limited to downloading at a slower rate for your 4K videos.

As soon as you drop lower – due to high contention rates at peak usage times, say – the picture will slip back into HD mode. And don’t worry if you start off with a blurry image: it’s quite common for streaming services to start a programme at a low resolution and then bump it up to HD and UHD after the initial buffer.

Other key things to consider:

  • Screen size: 4K looks best on larger screens, but you do not necessarily need a 75-inch TV that dominates the room to get the best results.
  • Sound: Many 4K TVs come with built in sound bars which will provide decent quality sound to the room, but you may want to invest in a speaker system for better results.
  • Connectivity: Check the number of HDMI and USB ports the model has. Four HDMI ports may be necessary if you have several gaming devices.
  • Brightness: If you plan to watch TV in a dark room then a TV with an OLED screen will give greater contrast and have better blacks and darker colour, in a lighter room the difference will be less pronounced.
  • HDR compatibility: Given this is such a new technology many video apps or services do not even support the content except on certain TVs. Amazon has a list of compatible HDR models for its video app here, while Netflix supports most brands.
