If you can afford to spend a few thousand quid on a computer screen, you can buy yourself an UltraHD or 4K monitor. But does your PC support such high resolutions? What do you need to get the most out of it, both as professional and as a gamer?

Last year August we reviewed our first 4K monitor, the 31.5-inch Sharp PN-K321N with a resolution of 3840x2160 pixels. That's four times Full HD and will set you back about $4,999 (£3,195).
