@xx4L0Mxx Did you write the correct numbers (XXX) in "ModeTimingOverrides_DP_XXXXXXXXXXX" with the same you have in your "UserForceModeSupport_XXXXXXXXXXXX"? Be aware that the hex codes posted by jeckop had empty spaces! If you try to add it to registry it will say sucess but nothing is added. Chech the keys after integration in registry. It must work for you cause you have the same card: "290". Maybe the hex codes for "290X" are different who knows.
