nVidia Dual Monitor (VGA/DVI-D) causes both to go blank

2 posts in this topic

Recommended Posts

I have run into an issue with dual monitors that might be less unique than I might think, although I haven't been able to find this exact issue anywhere.

I have an OSx86 Lion (10.7.3) system with a GeForce GT 620 PCIe (EVGA), and both monitors will go into "Sleep Mode" when they're both plugged in. No matter what port I use, as long as I just have one plugged in, everything works fine. I've tried NVEnabler, which locks up at:
NVEnabler: probe: ROM shadow enable

I have also tried installing official GeForce/Quadro drivers from nVidia's site for 10.7.3, which gave me native resolutions, but didn't fix the dual monitor issue.


Other specs:
Dell Inspiron 530
Core 2 Quad @ 2.40 GHz


Thanks in advance

Is important the port that you use.

If you use DVI to one monitor the recommended is you use the same to other.

Maybe this cause your issue.

But is very important check if you active your graphic, see how: http://olarila.com/forum/viewtopic.php?f=28&t=154

All graphic kext are in mac, so aren't necessary download them.

Good Luck!
