REVIEW: Samsung C27A750X LED Part 8

sRGB: 86 % coverage

The ISO Coated and sRGB colour spaces are covered at an average level only by the Samsung C27A750X at 84 and 86 percent respectively. The undercoverage is worst in the green and blue sections. Here, it is very probable that colour gaps will arise in colour-management environments.
