All three new Galaxy S22 variants have just launched with displays made of first-party Dynamic AMOLED 2X, have 120Hz refresh rates and are protected with the latest Gorilla Glass Victus+. However, the Ultra version is the only one with an Adaptive Refresh mode that can go down to 1Hz rather than 10Hz. It also contains some other upgrades that has its maker calling it "our most advanced display yet".
