Our Verdict

Dell Alienware AW3423DW

Sony 42 A90K OLED

The Dell Alienware AW3423DW is better than the Sony 42 A90K OLED. The Dell offers much better gaming performance, with significantly lower input lag and support for both G-SYNC and FreeSync variable refresh rates. The Dell also has a much more versatile stand and better reflection handling. On the other hand, the Sony has a full-featured smart interface built-in, so if you like to watch streaming movies and shows, you can do it on the Sony without even powering up your PC.
