Updated to latest driver. Now system won't recognize second monitor. I uninstalled and used DDU as suggested in different post. I also read post suggesting that the problem was because second monitor no longer needed to be connected to second Vid Card. My monitors are both connected via hdmi and there isn't a second hdmi connection available on the cards. I did restore the system to an earlier point and both monitors worked as expected. I lose some settings that I'd like to keep if I keep the system as restored, so I'd like to correct the current installation if possible. Anybody have any ideas?
