Our Verdict
Samsung Odyssey G50A S27AG50
Samsung Odyssey G55A S27AG55
The Samsung Odyssey G50A S27AG50 is much better than the Samsung Odyssey G55A S27AG55. The S27AG50 has a much better design, with a full range of ergonomic adjustments, so you can better place it in an ideal viewing position. The S27AG50 also has a much faster response time, resulting in clearer motion, and it gets a lot brighter to overcome glare.
