In the wake of Sony’s announcement of their Pro version of the PS4 supporting upscale 4K, and Xbox also pulling out the supposed upscale 4K with their One S, it begs the question, what exactly is upscaling and how is it different to native 4K resolution?
First of all, what is 4K? 4K basically refers to a display resolution of 4000 pixels horizontally and 2000 pixels vertically. Right now the industry standard for consumers is 1080p, which refers to 1920 pixels horizontally and 1080 pixels vertically. What this means is basically a resolution that’s nearly four times the detail of today’s industry standards.
Native 4K is still in it’s infancy and thus very expensive to maintain, as you need a powerful PC rig to output at 4K natively, not to mention having a monitor/TV that is capable of displaying 4K. Therefore, that’s where the current technological trends for gaming lies; in upscaling.
