I upgraded to this card and have my 27" ACD connected to it with a DP to MDP adapter. Screen saver comes on, but the display does not shut off. Anyone know of a fix for this?
Does your Mac Pro go to sleep mode regularly?
Just realized you were referring to the monitor sleeping, not the Mac. Do you have the "turn display off after" setting enabled in System Preferences > Energy Saver?
Yes, the display is set to sleep after 15 min and the computer is set to sleep after 1 hour of inactivity. Yes, it's been rebooted.Did you try re-boot / logout and login yet? Assume you have correct setting in system preference
Yes, the display is set to sleep after 15 min and the computer is set to sleep after 1 hour of inactivity. Yes, it's been rebooted.
Card was new and the only other variable is the DP to MDP adapter from the ACD to the card.Were you using this monitor and cable with a different GPU before getting the 580? That is to say, is the 580 the only variable that changed (aside from installing Mojave)? And was Mojave a clean install or upgrade install?
Edit: Did you buy the card brand-new in box? Or was it purchased used?
