Brightness and Contrast
The closeness between AD27QD and FI27Q-P ought to come as no surprise; the latter may enjoy a higher 165Hz refresh rate and DisplayPort 1.4 connectivity, yet image quality is understandably similar. Both the black levels and contrast ratio aren't quite up to the standards set by VA rivals, and while brightness is above average, DisplayHDR 400 certification isn't enough to deliver what we would describe as a true HDR experience.
