Our Verdict
Razer Raptor 27 165Hz
Dell Alienware AW2721D
The Razer Raptor 27 165Hz and the Dell Alienware AW2721D are great 1440p gaming monitors with some differences. The Dell has a 240Hz panel with native G-SYNC support, and it has a much quicker response time, while the Razer is a 165Hz monitor with FreeSync support. The Dell gets much brighter, but the Razer has better reflection handling. The Dell has better ergonomics, making it easier to place in an ideal viewing position. The Razer has a USB-C input, which the Dell doesn't have, meaning that you can connect compatible USB-C devices with it.
