Full HD on a 4K monitor looks worse than on a Full-HD monitor.
This happens due to blur added by monitors and graphics drivers at any scaling ratio, though this could be avoided when enlarging by an integer number of times (e. g. 2 in case of FHD→4K).
As a result, sharpness in 3D games is decreased, white lines are gray, and pixel art is not pixel art anymore.
Each logical pixel could be displayed as a square group of integer (2×2, 3×3) number of physical pixels of the same color.
Such lossless scaling could be built into graphics drivers, this would automatically remove blur regardless of what monitor is used.
