Out-of-the-box, the ASUS ProArt PA278QV has good color accuracy. The monitor has an sRGB mode that’s factory-calibrated and comes with a calibration report in the box. It’s advertised to have an accuracy that’s below 2dE; however, some of our measurements exceed that. This is likely due to different methods of measuring color accuracy.
Most of the color inaccuracies are difficult to spot, but white balance is off due to the warm color temperature giving the image a reddish tint. Gamma follows the target curve reasonably well except for bright scenes, which are over-brightened.
