Dell Alienware AW2721D
ASUS ROG Swift PG279QM
The Dell Alienware AW2721D and the ASUS ROG Swift PG279QM are very similar, each with strengths and weaknesses. The Dell has a better vertical viewing angle and better ergonomics, and it's brighter in both SDR and HDR. The ASUS, on the other hand, has better reflection handling and a wider color gamut, and it has built-in speakers.
