I am using Windows 8 with Sapphire HD7950 Vapor-X 3G 384bit GDDR5 PCI-E 3.0 Video card 950MHz/1250MHz (Dual DVI+ HDMI + Display Ports).
I have 3 LED Monitors (all LG 23'' wide screens). One of them is connected with HDMI and another two is connected with DVI-D cables to the graphics card.
Here is what my graphic card looks like:
When I "Detect" the displays in the Screen Resolution dialog in Windows 8, it can detect 3 monitors.
However I can only use two monitors at any time. When I enable all 3 monitors, I get the following message from Windows:
The display settings could not be saved. Please try a different combination of display settings.
I can only use LED 1 and 2, or 2 and 3, or 1 and 3 at any time. I cannot use all LEDs 1, 2, and 3.
Any ideas what I'm missing?
