Custom Resolution Utility (CRU)

[tombom]

Hello
i am trying to change my S95F's VRR range because it is flickering considerably

However, when i go to "Extension Block -> HDMI 2.1 Support -> Variable Refresh Rate" I cannot increase the lower limit (the number turns red and i cannot click "ok"), I can only decrease it.

this is on a 5070ti. I can add custom refresh rates so EDID overrides do not seem to be ignored on this GPU (Samsung's stupid one connect box has DSC activated and the ports are only 40gbps).

any (other) ideas on how to decrease VRR Flicker would be much appreciated. The VRR flicker is driving me crazy on this otherwise awesome TV
