I posted this on another thread but thought I may add it to this one as well.
I have three monitors. Two Generic VGA Monitors (I think the brand is Envision) and and a Hanspree HD monitor with an HDMI and VGA interface. I have an Sapphire hd 5770 with a DVI, Display Port, and VGA interface. I am running Windows Vista 32bit. I have the DVI interface on the graphics card going to one of my generic monitors with a DVI to VGA adapter (passive). I have the VGA interface on the card going to the other Generic monitor. I have the Display port going to the HDMI interface of the Hanspree monitor using a Display port to HDMI cable i purchased from Monoprice.
When I open catalyst control center I see all three monitors in the bar at the bottom of the display group screen. When I right click to create my display group the software only gives me the options of 1x2 vertical or 2x1 horizontal.
Is this due to the two VGA monitors? I can create a 2 monitor group over any two monitors, but not a three monitor group.
