People are realizing what the mysterious logos on your TV really mean

BUYING a new TV and confused by the jargon? It’s enough to get your head spinning.

We’ve rounded up some of the top logos, symbols, and phrases to look out for in a handy guide.

4K

4K refers to the number of pixels on your TV screen – or “picture resolution”.

Pixels are the tiny dots of color that make up the picture you see on your TV.

A pixelated image is one where the pixels are really obvious because there aren’t many.

But images with lots of pixels – like a 4K film – generally look sharper and clearer.

A true 4K screen is 4096 x 2160 pixels. This means that there are 3840 pixels across and 2160 pixels vertically on your TV screen. That’s a total of about 8.3 million pixels on the display.

4K gets its name because it has four times the number of pixels than a standard Full HD TV.

Full HD (or 1080p) screens are 1920 pixels across and 1080 pixels up – for a total of about two million pixels.

So 4K just means your TV has a lot more pixels on the screen than a more traditional Full HD display.

Ultra HD / UHD

Ultra HD or UHD is basically the same as 4K.

If you buy a UHD TV from a store, you can easily watch 4K content on it.

But there is a small difference.

Almost every television you will ever buy has an aspect ratio of 16:9. This means that for every 16 pixels horizontally there are 9 pixels vertically.

True 4K footage doesn’t quite fit that ratio, so you won’t often find 4096 x 2160 pixel TVs.

Instead, to match the 16:9 ratio, most 4K TVs have 3840 x 2160 pixels instead.

If it doesn’t make sense, grab a calculator and divide 2160 by 9. Then multiply it by 16 and you get 3840. That’s the aspect ratio that works its magic!

So when you’re looking at an Ultra HD TV, that just means it’s a 4K picture with slightly fewer vertical pixels.

OLED

On a standard TV or smartphone, you have an LCD (or liquid crystal display) screen.

This means your screen contains many tiny crystals that are illuminated by a giant backlight on the back of your TV or phone. When the crystals light up, you see a picture – and that’s TV!

However, OLED screens work a little differently.

OLED stands for Organic Light Emitting Diode and is a way of describing the type of screen on your TV or phone.

It’s basically an organic compound that emits light when you pass an electric current through it.

This means your OLED screen doesn’t need a big ol’ backlight as the pixels on your screen will light up on their own.

OLED screens are generally better than traditional LED-backlit LCD displays.

First of all, they are much more energy efficient. That’s because you’re not paying to power a huge backlight that consumes tons of energy.

But the lack of a backlight also means OLED screens can be much thinner.

The big advantage of OLED is the improvement in picture quality.

You never really see black on a normal TV because there is a backlight.

On OLED screens, individual pixels can be turned off entirely or greatly dimmed, allowing you to see much more accurate blacks in dark TV or movie scenes.

In general, this means that OLED screens offer a greater range of light, dark and color overall.

HDR / HDR10 / HDR10+ / Dolby Vision

This stands for High Dynamic Range and simply means that a piece of video has improved contrast (so better highlights and darks) and a wider range of colors.

Netflix and Amazon both offer a lot of HDR content, but you need to make sure you have an HDR TV to watch it – otherwise you won’t see any difference.

HDR is not just HDR – there are many different types.

But there are three key HDR formats you should know about: HDR10, HDR10+, and Dolby Vision.

They each offer slightly different versions of HDR, some better than others.

Dolby Vision is widely considered the best of the trio.

But if you’re short on cash, it’s good to have one of the main HDR formats.

8 THOUSAND

8K TVs are the next step up from 4K, increasing the total number of pixels yet again.

For an 8K TV, the resolution is 7680 x 4320 pixels, or about 33 million pixels in total.

So if you want to watch 8K content, you’ll see an extremely detailed picture.

There are many reasons why buying an 8K TV when it comes out would be silly, but we’ve narrowed it down to three big ones.

The first is that it’s basically impossible to tell the visual difference with a living room size 8K TV.

That’s because on small living room TVs, the pixels are so densely packed that beyond a certain point the human eye can’t see any improvement.

With HD and Full HD televisions, you would need a screen of at least 42 inches to be able to tell the difference – at a reasonable viewing distance.

And to see the benefits of a 4K TV, you’d need a 50″ TV 5 feet away or an 80″ TV 7 feet away to tell the difference.

You need an absolutely massive TV – well over 100 inches – and an extremely short viewing distance to see a noticeable difference between a 4K TV and an 8K TV.

The second problem is that there just isn’t enough 8K content in the world.

An 8K TV is only half the battle – you also need movies and TV shows shot in 8K, which is expensive and time-consuming to produce.

We’ve had 4K TVs for years, and there’s still a dearth of quality 4K content.

So why buy an expensive 8K TV when there hasn’t been any decent content for it for years?
