HDMI on Xbox Series X: what you need to know

techradar.com:

The Xbox Series X is now available to buy, giving a big boost to the capabilities you’d expect from previous home consoles. 

Unfortunately, stock issues are still preventing many people from finding an Xbox Series X (orXbox Series S). But whether you’ve been lucky enough to find one yet or not, it’s worth considering that the new Xbox Series X’s HDMI capabilities – and its TV capabilities – are different to what you’d expect to find on a current-gen console. 

Both the Xbox Series X and Series S come with an HDMI 2.1 connection as standard. It's worth noting, though, that while the Xbox Series X comes with an HDMI 2.1 supporting cable, the Xbox Series S only comes with an HDMI 2.0 cable – which we'll look at in more detail below.

This allows the consoles to support a max 120fps (frames per second) in games running at 4K resolution. What this means when it comes to console gaming is a huge leap forward in gameplay, speed and performance. For comparison, theXbox One X could only hit 4K/60fps, meaning the bar has been significantly raised for this console generation.

Not only does HDMI 2.1 allow for much better frame rates, it also means you can transfer any 4K and even 8K image qualities from your games console to a compatible TV. The biggest caveat here, however, this is that 8K gameplay will be limited to 60fps – although you likely won't be playing any 8K games for a while.

The Series S, on the other hand, comes with HDMI 2.1 port but an HDMI 2.0 cable («high
