GTX 680 second screen blank/black?.
Hi,
I recently swapped an EVGA GTX 680 into my system as both an upgrade from a Quadro FX 380 (which was pretty underwhelming) and because it was a lot easier than continuing to fight with the problematic 270x I had initially tried.
Anyway, the core part of the system is:
HP Z800 Workstation
Dual Xeon x5670 6-core processors @2.93GHz
48GB ECC Registered DDR3 1333 RAM installed (12 x 4GB sticks)
EVGA GTX 680 (DVI-I, DVI-D, HDMI, & Disaply Port available as outputs)
OS X 10.8.5
I run a pair of Samsung S24D590 LED displays in order to work efficiently, however, with this new graphics card I am only able to get a picture on one of the two displays.
a) My left-hand (primary) display is connected via the DVI-I port on the card -> DVI-to-VGA adapter -> 15' VGA cable -> VGA port on the monitor and works just fine.
b) My second display I have attempted to connect via the card's HDMI port (and the DVI-D port -> DVI-to-HDMI adapter) -> HDMI cable -> HDMI port on the monitor (I have tried both ports on the monitor), but the display just shows a blank/black screen.
Note: The display seems to correctly identify that there is a signal or something on the given HDMI port as it will stop cycling sources on the connected HDMI port. I have also tried any combination of "Display Settings" within OS X 10.8.5 without any change.
Any suggestions would be much appreciated.
Thanks,
