Our Verdict
Samsung Odyssey OLED G81SF S27FG810S
Dell Alienware AW2725Q
The Dell Alienware AW2725Q and the Samsung Odyssey OLED G81SF S27FG810S are 27-inch 4k QD-OLED gaming monitors. Both models are extremely similar, apart from their screen finish. The Samsung has a matte screen, while the Dell has a glossy screen, so you may want to choose between them based on whichever type of finish you prefer. Otherwise, given their similarities, you may want to get whichever costs less.
