Our Verdict

ASUS ROG Swift OLED PG27UCDM

Samsung Odyssey OLED G81SF S27FG810S

The ASUS ROG Swift OLED PG27UCDM and the Samsung Odyssey OLED G81SF S27FG810S are 27-inch 4k QD-OLED gaming monitors. Unlike the ASUS the Samsung has a matte screen finish, so you may want to choose based on your preferred screen finish. That said, the ASUS is a better option if you plan to use it for productivity as well as work, as it has a KVM switch and delivers 90W of power over USB-C.
