4K, UHD, HDR, HDMI...the world of smart TVs is littered with incomprehensible acronyms—so what do they all mean? And do you really need them? Here’s what you need to know.

Most of the TVs on sale these days are “smart” TVs. This means that they come with built-in apps that let you stream content from a variety of online sources. Many of them also either have integrated technology that means they can be used with home assistants, such as Alexa or Bixby, or can be configured to work with them.

Most of the acronyms around relate to picture quality. 4K and UHD (which stands for ultra high definition) are used synonymously—they relate to the number of pixels that can fit across the screen (4,000) and are all about the resolution. HDR, on the other hand, stands for high dynamic range, which relates to the colours that you’ll see on screen. It’s a technology that means you can see bright tones without them being overexposed and dark tones without them being underexposed.

We’ve talked about your TV’s image output but you might also want to know what inputs or ports it has. If your TV is smart and connected to your WiFi network, it should be easy enough to cast to it from a phone or laptop, but depending on what else you might like to communicate with it—computers, extra speakers, headphones—you might want to check on that. Most will come with an HDMI port, but you will often also find USBs and headphone jacks as well. Some will also have a Bluetooth connection.
