Kuebeker Posted November 5, 2016 Share Posted November 5, 2016 Sierra 10.12.1 r.16b2657 GTX980 Nvidia driver WebDriver-367.15.10.15f03.pkg Single Monitor = OK. Dual or triple monitor = I get a black screen, intermittently I can see my mouse curser. Any solutions? Link to comment Share on other sites More sharing options...
cnrd Posted November 5, 2016 Share Posted November 5, 2016 If you have it disabled, try enabling CSM support (Not sure which motherboard you use, but on my GA-Z170X-UD3, the settings below work). Windows 8/10 features: Other OS Everything below (except LAN): UEFI Only Link to comment Share on other sites More sharing options...
Kuebeker Posted November 5, 2016 Author Share Posted November 5, 2016 Well I have no fracking clue what I did but triple monitor works. Not entirely true, I did select the graphics via PCI-E in my bios, reboot, selected PEG, reboot, reselected PCI-E rebooted. Cant say if this is it since I have not been able to reproduce my black screen . I have the Maximus VII Hero. The option is location in System Agent Config, Graphics Config. For sure if/when I figure it out I will report back. Forgot to look at the CSM. I'll brb with the info. CSM is enabled. I did not do the off/on reboot dance.
