Our Verdict
ASUS ROG Swift OLED PG27AQDM
Acer Predator X27U bmiipruzx
The ASUS ROG Swift OLED PG27AQDM and the Acer Predator X27U bmiipruzx use the same panel but have a few differences. The ASUS gets brighter in HDR and also has an improved color volume for more vivid colors. The ASUS also has lower input lag for a more responsive feel, but only after a firmware update. On the other hand, the Acer has a few extra features, like a KVM switch and a USB-C port, making it easier to connect multiple devices. It also has a more ergonomic stand, so it's easier to adjust.
