monolithic Posted May 9, 2016 Share Posted May 9, 2016 Gigabyte GA-P55a-UD3 mobo nVidia GTX 770 video Left monitor works. Right does not. I've downloaded and installed the nVidia web driver. Issues persists. Screen flicker whenever I'm using Safari. Any ideas? Thanks in advance, M.

monolithic Posted May 10, 2016 Author Share Posted May 10, 2016 My system is set for either 2,1 or 3,1 Power Mac. At work right now so I can't check. Does anyone have any insight as to a possible solution? Many thanks in advance, M.

monolithic Posted May 13, 2016 Author Share Posted May 13, 2016 Ok, I fixed this on my own. I want to post the solution in case anyone else is having a similar issue. 1. I edited config.plist in /EFI/clover/ and in that file under <key>Graphics</key> Intel was set to true. I changed that to false as I have an nVidia GTX 770 and no onboard video on my GA-P55A-UD3. 2. In Clover boot options I entered in nvda_drv=1 and removed nv_disable=1 This fixed the issue with my second monitor not working. Both monitors work fine and are using the latest nVidia web drivers and I'm running El Capitan. SCORE! Now to fix my funky USB keyboard issue. Hope this helps someone in a similar boat. M.
