Our Verdict
Samsung Odyssey G50A S27AG50
Gigabyte M27Q P
The Samsung Odyssey G5 S27AG50 and the Gigabyte M27Q P are both impressive gaming monitors. They have similar specs with a 1440p resolution and 165Hz native refresh rate, but the Gigabyte has an overclock feature to go up a bit to 170Hz. However, the Samsung monitor still has a faster response time at any refresh rate, leading to less motion blur, and this model has lower input lag with 60Hz signals. The main advantage the Gigabyte has is that there are a few office-oriented features, like a USB-C port and a KVM switch. The Gigabyte also displays a wider range of colors with better accuracy, especially in HDR.
