The Samsung Odyssey G7 S28AG70 is the first 4k monitor in Samsung's Odyssey gaming lineup. It has a 144Hz refresh rate with HDMI 2.1 inputs, meaning you can achieve its max refresh rate with a 4k resolution over both DisplayPort and HDMI connections. The two HDMI 2.1 inputs support 4k @ 120Hz gaming from the Xbox Series X, PS5, or PCs. There's native FreeSync variable refresh rate (VRR) support, and it's certified by NVIDIA to be G-SYNC compatible. It's different from the Samsung Odyssey G7 C32G75T because it has a flat screen, and it has an IPS panel with wide viewing angles, which also means it has a low contrast ratio that makes blacks look gray.
