Frequently Asked Questions About Budget 4K TVs
What does 4K mean for TV?
Simply put, 4K refers to the overall resolution of a television's panel. In terms of numbers, a 4K resolution clocks in at 3840 x 2160, meaning there are 3840 pixels by 2160 on a panel.
To put this into context, it's four times the HD standard of 1920 x 1080, leading to a much greater quality of the projected image. These can be made even more vivid providing the TV has a good backlight.
Is 4K really better than 1080p?
Undoubtedly so. For anything from gaming on a next-gen console or watching ultra-HD content, then 4K certainly provides plenty of real-world benefits to 1080p.
Arguably it's a lot better up close as it becomes easier to distinguish between the two. Changing over to a 4K TV is one of the best purchases to make, even if content providers on traditional TV are still operating at 720p or 1080p.
Is 4K good for gaming?
Practically every next-gen console - that is from the Xbox One X/PS4 Pro onwards - supports 4K in its various guises at all sorts of different frame rates.
Having a suitable and compatible TV to work with these consoles can lead to much better picture quality and therefore gaming experience overall. If you want to take it one step further, getting a dedicated soundbar can take things to the next level.
For the Xbox Series X and PS5 though you'll want to make sure your 4K TV supports 120Hz and HDMI 2.1 to maximise performance, although this may come at a cost.
