TV buying guide

Choose your TV in six easy steps...

4K Ultra HD, 8K TVs, HDR, OLED, QLED – what does it all mean?

With so much innovation in screen technology, checking through the specification for the latest TV can feel overwhelming. That’s why we’ve broken down the process of choosing the perfect screen for your home into six simple steps.

Whether you’re purchasing your first TV for your new pad, looking to upgrade from your old HD TV, or simply after a second smaller screen for the bedroom or kitchen, we’re on hand to help so you’re not left scratching your head.

Screen size

That 75” TV sure looks impressive on the shop floor, but will it fit into your space? Think about your layout, how close you’ll be sitting to the screen, and how many people will be watching.

Which screen size should I go for?

A good place to start is by working out how far away you’ll be sitting from the screen. You can use the handy diagram here as a good rule of thumb for screen size as it shows the most comfortable viewing distance.

Of course, the figures on the diagram are just suggestions, and the size of your TV is ultimately down to personal preference.

How has TV screen size evolved over the years?

An evolution in screen resolution has meant screens can be larger without showing pixels. They’re also slimmer, with narrower bezels surrounding the screen. Some manufacturers even have bezel-less designs that are made to be so discreet they fit into your surroundings.

All this means you can fit more screen into the same space as you used to be able to. A modern 50” TV takes up roughly the same size as a 42” TV did back in 2008, so if it’s been a while since you bought one, consider going up a few sizes.

Why should I invest in a super-size screen?

There’s more to purchasing a super-size screen than just keeping up with the Joneses. You’ll find the best picture quality on larger screen TVs, with manufacturer’s reserving premium OLED and QLED displays and added features for their super-size models.

Viewing angles are vastly improved, so everyone in the room can watch in comfort – great for family movie nights.

Screen technology

QLED, OLED, LED. They all sound similar, so what’s the difference? It’s an important consideration when purchasing your new TV – after all, what’s the point in a large screen that doesn’t do your entertainment justice?

What is OLED?

OLED stands for Organic Light Emitting Diodes. Individual pixels create their own light source to make up the picture, so they can turn themselves off completely to show the deepest blacks.

That’s the science bit. What this means for you is a premium viewing experience with deeper blacks, more vibrant colours, greater contrast, and improved viewing angles.

OLED TVs also have a lower energy consumption than LED and the screens can be super-slim.

What is QLED?

QLED stands for Quantum Dot Light Emitting Diode (yes, the D has been dropped). However, the technology has developed beyond what is stands for. All QLED TVs have a quantum dot filter, a film of tiny particles which can be precisely controlled for their colour output.

The advantage of this is 100% colour volume – you get a wider, more diverse range of true-to-life colours, no matter what conditions you’re viewing the screen in. You also get higher peak brightness, meaning HDR content looks great.

And now with 8K QLED TVs on the market, there’s even better choice when shopping for a QLED TV. You can expect enhanced resolution – an impressive four times the resolution of 4K – with all your favourite content upscaled to 8K.

What is LED?

LED stands for Light Emitting Diodes. It works by using a backlight which is shone through an LCD panel to produce the individual pictures.

While not as premium as OLED or QLED, there’s still plenty of reasons to consider an LED TV. Easier and cheaper to produce, you’ll have the choice of a wider range of TVs. Manufacturers often apply their own technology for an improved picture, and look out for HDR which improves colour and contrast.

Picture quality

Think all 4K Ultra HDs are the same? Think again. Be confident that you’re getting the best picture quality and true HDR support with a Certified Ultra HD Premium TV.

Why is a 4K Ultra HD TV better than a full HD 1080p TV?

4K Ultra HD TVs have a resolution of 3840 x 2160 pixels – that’s four times greater than a Full HD display. This means you get better picture quality with greater detail, especially noticeable with larger screens.

Native 4K content is needed to take full advantage of a 4K Ultra HD display, and there’s more and more content available daily. However, many TVs can upscale Full HD to 4K quality too, so you can enjoy improved picture quality over a Full HD TV.

What is 8K and how is it better than 4K?

So, we’ve discussed how 4K is better than Full HD, but what about 8K and is it worth considering? At 7,680 x 4,320, the resolution is a whopping 16 times greater than HD, and four times greater than 4K. That’s quite a big step up, and as you’d expect movies, TV shows, and sports are all shown in impressive detail to make your entertainment experience even more immersive. On a 65” screen you wouldn’t even be able to make out the pixels.

8K content may seem like a long way off, but it’s already happening. And for those that can’t wait, an 8K TV will upscale all your content, so you can enjoy your favourite shows in a whole new way.

What is the difference between 4K Ultra HD and 4K Ultra HD Premium?

Not all 4K Ultra HD TVs are created equal. Where you see the Ultra HD Certified logo, you’ll find that true UHD standards have been met. These standards are set out by Digital Europe so you can be confident you’re getting brilliant image quality.

4K Ultra HD Premium from the UHD Alliance takes it a step further with advanced standards, including support for HDR. Wherever you see the Certified Ultra HD Premium logo, you’re guaranteed a TV that can produce a wide range of colours with vibrant details, and brilliant contrast with HDR.

Last but not least, you’ll also want to keep an eye out for the 4K HDR Ultra HD logo from Eurofins. As well as standards for 4K Ultra HD and HDR, they also have strict requirements for the way HDR content is received and displayed over broadcast and broadband, in addition to HDMI.

What is HDR technology and how can this benefit my viewing experience?

HDR stands for High Dynamic Range, a term you might’ve heard used in photography. Basically, it means you get improved contrast, greater levels of brightness, and a wider colour palette. It makes a big difference to your content – movies and TV shows look more realistic, with natural, true-to-life colours.

To appreciate HDR, the content you’re watching needs to support the same HDR standard, but some TVs offer HDR-quality upscaling for non-HDR content too. There’s multiple HDR standards, so it’s worth considering which standards your chosen TV supports.

HDR10 applies HDR scene-by-scene and is a popular form of HDR with support from Amazon, Netflix and the Blu-ray Disc Association.

Although not as common, Dolby Vision and HDR10+ applies HDR frame-by-frame for a subtler, more improved image.

Developed in conjunction with the BBC, Hybrid Log Gamma (HLG) has been designed with TV broadcasts in mind and can be found on a wide range of HDR TVs.

What can I watch in 4K Ultra HD?

While 4K Ultra HD TVs have been on the market for a while, content has been slow to catch-up. But that’s starting to improve with new content available daily.

You’ll find a wide range of popular Hollywood movies are available on 4K Ultra HD Blu-ray discs which really do the films justice. You can enjoy popular sports in 4K on BT Sport 4K UHD and Sky Sports UHD.

You’ll also find that streaming services like Netflix, Prime Video, and YouTube are quickly expanding their range of 4K Ultra HD content with HDR – all you need is a TV or media player that supports these apps in 4K and a fast broadband connection.

Smart TV

Extra media streamers and boxes can make clutter. So why not pick a TV with everything you want built-in? Smart TVs offer catch-up and on-demand streaming services like Netflix, Prime Video, and BBC iPlayer. The amount of 4K content is growing every day and even if your favourite show is not available in 4K, a 4K TV will upscale it and enhance the viewing experience.

What is a Smart TV?

A Smart TV connects to the internet using either your home WiFi or Ethernet. Similar to your smartphone, it has an on-board smart platform with a homepage that’s usually customisable. This gives you access to a range of apps, such as catch-up, on-demand, social media, and gaming apps.

What can I watch on my Smart TV?

Each TV manufacturer has a different selection of apps, so check they have what you want before you buy. You’ll find popular apps such as BBC iPlayer, ITV Hub, Netflix, Prime Video, and YouTube on most TVs.

You’re not just limited to entertainment apps either, many TVs will have a selection of social media, lifestyle, news, and gaming apps.

What are the benefits of 'voice control'?

If you’re familiar with Google Assistant, Amazon Alexa, or Apple’s Siri you’ll find many TVs offer a similar voice control service. If you haven’t used voice commands before, don’t worry, it’s user friendly and simple to use.

With voice control (usually via the remote) you can use commands to find what you want, navigate, change settings, and more. For example, you could ask your TV to “play Peppa Pig on Netflix”, “change to sports mode”, or “turn off when this program ends”. It’s a handy way to control your TV without navigating menus or using on-screen keyboards.


Brilliant visuals deserve brilliant audio. The right speaker can bring documentaries to life, ramp up the tension with a dramatic film score, and make concerts sound epic. So how do you choose the best sound to match your TV?

Do I need a sound system for my TV?

All televisions have their own built-in speakers to deliver sound, but unfortunately as TVs have become slimmer with thinner bezels there’s less space for front-facing speakers. This means built-in speakers and specially designed surround sound systems can be worlds apart.

If you want deep bass, clear treble, and room-filling sound it’s well worth investing in a sound bar, soundstage, or home cinema system.

Soundbar, soundstage or home cinema system?

As the name suggests, a sound bar is a long bar-shaped speaker that sits beneath your TV. Most sound bars come with a wireless subwoofer so you don’t have to worry about trailing wires from your sound bar to sub (don’t forget your sub will still need a power source). You can get compact and all-in-one sound bars too if you’re limited on space.

A soundstage system is a flat speaker with more depth than a sound bar. It provides an all-in-one solution and generally includes a built-in subwoofer.

If you want deep bass, clear treble, and room-filling sound it’s well worth investing in a sound bar, soundstage, or home cinema system.

What is Dolby Atmos and how can this enhance my viewing experience?

You know that experience of sitting in the cinema - there’s a roar coming from somewhere in the jungle before a helicopter flies overhead? The sound envelopes you, so you almost feel like you’re there. Dolby Atmos brings all that breathtaking, immersive sound into your living room.

You can find Dolby Atmos in a variety of products, including TVs, sound bars, and home cinema systems. It’s well worth considering if you’re a film lover.

What is an invisible cable?

You want to wall mount your TV but you don’t want trailing cables on show? Before you start drilling holes in your wall, consider opting for an ‘invisible’ cable, a hard-to-see cable that can be run down the wall and along a skirting board without drawing attention.

Samsung’s extra length near-invisible cable lets you place all your devices out of sight and away from the TV for a clean look.
