008 0 Posted December 9, 2020 Posted December 9, 2020 (edited) Being on 10.15.6 + Clover my monitor (Samsung Curved 27 "CF591) with the HD 4400 card was able to refresh the image with the speed of 72 Hz. The same frequency was obtained under Winows. Currently under Big Sur with OC 6.3 in the settings is available only 60 Hz refresh option. Can it be changed somehow? I also installed SwitchResX but after creating a new profile, I cannot activate it. Edited December 9, 2020 by 008 Quote Share this post Link to post Share on other sites
