Our Verdict
Samsung Odyssey OLED G80SD S32DG80
Samsung Odyssey OLED G81SF S27FG810S
The Samsung Odyssey OLED G80SD S32DG80 and the Samsung Odyssey OLED G81SF S27FG810S are 4k QD-OLED gaming monitors. The biggest difference between the two is their size, as the G81SF has a smaller 27-inch display, and the G80SD has a larger 32-inch screen. Otherwise, they both have very similar performance, though the G80SD does have an integrated smart OS and remote, which you may prefer if you plan to use your monitor like a TV.
