Our Verdict
Samsung C34F791/CF791
ASUS ROG Swift PG279Q
The ASUS ROG PG279Q is a much better monitor than the Samsung C34F791/CF791. If you play a lot of games, the ASUS has significantly better input lag, slightly better motion blur and supports G-SYNC to smooth out tearing. Also, the ASUS has better viewing angles, which is great if you wish to use it at the office.
