sphinx84 Posted August 18, 2023 Share Posted August 18, 2023 (edited) Hi there. I use 4K TV as monitor which connected through HDMI on PC. Current OS is - BigSur (but I had another too). In the screen settings no refresh rate, no list of resolutions. Current refresh rate is 50Hz. How can I change that? My TV is supported 4K 120Hz but I want 2K 75Hz or high refresh rate. What should I do? Edited August 18, 2023 by sphinx84 Link to comment https://www.insanelymac.com/forum/topic/357458-no-choice-of-the-refresh-rate/ Share on other sites More sharing options...
