I find 4K i s mandatory for 27 inch display. At this size, you only have 163 ppi, which is still far from the 218 ppi of a retina display. 1080p on 27 inch will look disgusting, incredibly pixelated. My U2414H, which is 24 inch 1080P, already look pixelated as hell and it was one of the highest end displays at that time at Dell. I can’t even imagine 27 inch at 1080p. The best recommendation I could give you is save your money, don’t buy this sh*tty thing, wait a bit and take an affordable Dell S2721QS 4k 27 inch monitor. You won’t regret this decision, trust me !!! Two years running an awfull monitor can be very, very long.
