The PA248Q comes factory calibrated in its sRGB preset mode. To ensure that each PA248Q produces the most accurate and consistent colour, Asus carefully measure its ∆E (dE) and gamma value and track its grey-scaling. It also supports both Gamma 2.2 for PC and Gamma 1.8 modes for Mac, offering users more flexibilities to work with. Each screen has been calibrated to minimize colour difference to ∆E (Delta E) of less than 5. It comes packaged with a unique calibration report for your particular screen as well, as shown below.
