Our Verdict
Gigabyte M27Q (rev. 1.0)
Samsung Odyssey G50D S27DG50
The Gigabyte M27Q (rev. 1.0) and the Samsung Odyssey G50D S27DG50 are both 1440p gaming monitors. However, there are some differences between them. The Samsung monitor has slightly better motion handling at low refresh rates. On the other hand, the Gigabyte has a few extra perks, like a USB hub and a KVM switch, making it easy to change between sources and use the same keyboard and mouse on both.
