Our Verdict
Samsung Odyssey G7 C32G75T
Samsung Odyssey G55T C27G55T
The Samsung Odyssey G7 C32G75T is significantly better than the Samsung Odyssey G55T C27G55T. The G7 has a better contrast ratio, higher refresh rate, and much faster response time. It also has a better SDR and HDR color gamut, and it gets a lot brighter. On the other hand, the G5 has built-in speakers and is much cheaper.
