Our Verdict
ASUS TUF Gaming VG27AQL1A
Samsung Odyssey G50A S27AG50
The ASUS TUF Gaming VG27AQL1A and the Samsung Odyssey G50A S27AG50 are similar gaming monitors. They each have an IPS panel with a 1440p resolution. The Samsung has much better motion handling because it has a quicker response time at its max refresh rate and 60Hz, and it gets brighter, so it does a better job at fighting glare. The ASUS has built-in speakers and a local dimming feature, both of which the Samsung doesn't have, but the local dimming doesn't add much because it performs terribly.
