4K TVs at Comet



Buying a new television can be a big commitment, which means you might as well do it properly.

Since 4K televisions have become more affordable, now could be the best time to bring this type of quality into your living room. But what is 4K, and why should you pick your next TV with this in mind?

4K TV resolution



Screen resolution effectively dictates how clear the image will be, so a higher resolution image will look better. And, when it comes to resolution, the higher the number of pixels, the better the image quality and clarity. No ifs, no buts. Just facts.

This is because the display panels in TVs use pixels to display an image. Pixels are tiny squares that make up the base components of an image, and when there are more of these squares, the image can be more detailed.

So where do 4K TVs fit into the wider frame of screen resolution? There are plenty of terms bandied about when it comes to resolution, including 1080p and HD, to Ultra HD and 4K.

The previous standard, known as HD or 1080p, described screens with 1920 x 1080 pixels, which averages to roughly 2 million pixels on the screen.

4K on the other hand, is used to describe screens with 3840 pixels wide by 2160 pixels high, and is often also called Ultra HD. In terms of image quality, a 4K TV has over 8 million pixels in total - quadruple that of a HD TV. So, when it comes to immersive viewing, it’s crystal clear that 4K TVs are the winner.

Plus, with more and more content being recorded in 4K, having a TV that can keep up is essential to get the most from your favourite shows. However, one of the major benefits of an Ultra HD TV is that it can play lower resolution images - and can even adapt them to look better!

4K TVs are also perfect if you enjoy playing on the latest generation gaming consoles such as the PS5 and XBOX Series X. They’ll allow you to enjoy your games as they’re meant to be played - with incredible resolutions and high frame rates.

Screen size



Looking to set up a home cinema? Then size will definitely matter when you’re choosing your new TV. Larger screens need a higher number of pixels to make the image fit the screen at a high resolution, so if you’re going big, you need to go 4K.

4K TVs will always outperform HD, or 1080p, screens on a larger scale, which can make a drastic difference to your image quality. It’s simple maths.

Compare a 32 inch to a 43 inch TV screen. A 32 inch TV on average is 75cm x 45cm, whereas a 43 inch is around 97cm x 56cm. This is a lot of extra screen to cover. A 1080p image would struggle to fill the 43 inch screen, reducing the overall quality of the image - especially at a distance. A 4K TV however, has pixels to spare in making sure you’re getting the sharpest image clarity possible across a larger screen.

Choosing screen tech



Of course, choosing 4K is not technically the end of your decision making process. Screen technology has improved dramatically over the decades, and there are plenty of advances that you can choose from to suit your viewing style.

Mini-LED vs OLED vs QLED



If you’ve been looking for a new TV, chances are you’ve seen what feels like the whole alphabet after the title - but do you know what those combinations of letters mean?

The most common TVs have LEDs, or light-emitting diodes, behind the screen to provide the illumination they need to show an image. LED TVs are ideal for everyday viewing, in bright or darkened rooms.

But, by making a small change, we’re seeing big results with mini-LED TVs. With smaller LEDs, your TV now has more control over the colour contrast, offering you a better image quality overall. So, if you love watching daytime TV, or need the lights on for horror movies, you should consider a mini-LED TV.

If you prefer a wider range of colours and a brighter image, QLED could be the one for you. With over one billion colours available, getting accurate colour clarity is a cinch - which is perfect for bringing the delights of the big screen into your living room.

Are you a keen gamer, or love a cheeky late night movie marathon? Then OLED is the way to go. With self-illuminating technology, OLED screens can get the deepest blacks and brightest whites compared to other 4K TVs on the market for the ultimate viewing experience.

TL;DR: TV screens are not all made equal. Whether you’re a gamer, a film fanatic, or need your daily dose of drama, check out our table below for more direct comparisons across our 4K TV range.

HDR



Technology loves an acronym, and there are plenty to understand before picking the right TV for you. Most Ultra HD TVs have dozens of letters behind the name hinting at different features you can get - but one of the most important to bear in mind is HDR.

If you’ve ever complained that ‘TV is too dark these days’, then you need to consider a TV with HDR.

HDR stands for ‘high dynamic range’, and describes the range in which colours can be seen on the screen. Typically, anything below a certain brightness range would be black and the opposite is true for light whites. HDR extends this range, meaning that blacks are darker, and whites are brighter - which offers you a greater overall image quality.

When this is spread across the roughly 8 million pixels on a 4K TV, you get a vastly superior image to any predecessors. So, instead of squinting at the darkness of your favourite movies, do yourself (and your eyesight) a favour by picking an Ultra HD TV with HDR from Comet.

HDR has also been eagerly adopted by the gaming industry, with many top titles now supporting HDR. So, again, if you want to get the most out of your gaming console, buy a HDR-enabled 4K TV!

Smart technology



From Netflix and Disney+, to Amazon Prime and YouTube, streaming your favourite shows and movies has never been more popular - or easy.

In-built smart technology has revolutionised the way we approach buying a new TV, and is a key consideration when you’re choosing the model for you. So, alongside the superior image quality of a 4K TV, you should look for the smart capabilities that suit your lifestyle.

At Comet, we have a fantastic range of Smart TVs for you to choose from, including brands like Toshiba, Samsung, and LG.
