Our Verdict
Samsung Odyssey G7 C32G75T
Samsung Odyssey G55A S27AG55
The Samsung Odyssey G7 C32G75T is much better than the Samsung Odyssey G55A S27AG55. The G7 has much better ergonomics, so finding an ideal viewing position is easier. The G7 also gets significantly brighter and has a significantly better response time, resulting in clearer motion with almost no noticeable blur behind fast-moving objects.
