Question: what is the difference between full hd and ultra?
Answer: Ultra High Definition, or UHD for short, is the next step up from what's called full HD, the official name for the display resolution of 1,920 by 1,080. UHD quadruples that resolution to 3,840 by 2,160. ... 1080p — except that 4K should be labelled UHD, or 2160p.
