Our Verdict
ASUS ProArt Display PA278QV
Samsung Odyssey G55T C27G55T
The ASUS ProArt Display PA278QV is much better than the Samsung Odyssey G55T C27G55T; however, they aren't intended for the same use. The ASUS is a budget monitor for content creators with superb ergonomics and wide viewing angles. It also has a faster response time, but gaming feels smoother and more responsive on the Samsung due to its higher refresh rate.
