And the ASUS ProArt PA27AC actually offers plenty of features like that. I mean, do you see yourself using Thunderbolt 3 input, or daisy chaining Thunderbolt devices together? Or really use the 100% sRGB gamut and Delta E <2 color accuracy to finetune the color of your images and videos? Well, I don’t. But if you do, this might be the monitor for you, and the ASUS ProArt PA27AC isn’t even all that expensive in the grander scheme of things.PerformanceThe brightness of the display when measured at 100% brightness in the Standard mode was 279cd/m2, although by default the ASUS ProArt PA27AC comes out of the box with the brightness set to 50%, which corresponds to a 206cd/m2. We will be performing our testing on the Standard mode at the latter brightness, as that’s what’s default. In the sRGB and Rec.709 modes, the brightness measured was 168cd/m2.You can adjust the brightness in the Rec.709 mode, but the sRGB mode doesn’t allow you to touch any of the ASUS ProArt PA27AC’s visual settings. Turning on HDR and throwing the HDR/SDR brightness balance in Windows gets you the maximum 385cd/m2 in SDR content, but I can’t say that it is comfortable working with this brightness. Just leave it in auto and enjoy the monitor at the default 300 nits, with the extra brightness coming into play only when you are perusing HDR content.
