Additionally, you can use the included Acer Color Intelligence utility to optimize the color calibration to suit your tastes. That said, the differences between any scores less than 3.0 is hard to spot for most people.
The Acer's color accuracy was also slightly off, with a Delta-E rating of 1.32 (a perfect score is 0), compared with the slightly better ratings seen on the Asus Zen AiO Pro Z240IE (0.28) and the 21.5-inch Apple iMac (0.1). That's a far cry from the competition's results, which were all better than 100%, with fuller, visibly more-vibrant color as a result.
Color quality wasn't as impressive, with the Acer producing just 95.1% of the sRGB color spectrum.
