Hi folks,
I'm having a problem with configuring a triple monitor setup. I have a 2GB Radeon 4870 with a DVI and VGA output. I have my primary 24" LCD connected to the DVI connector and secondary 22" LCD to the VGA connector. They both work perfectly in a dual monitor setup using the latest Catalyst drivers (it's a relatively new build PC).
Earlier this month I had the arguably hedonistic idea to add a third monitor for work purposes. I do graphic/web design as well as complicated database work, for the most part, but after switching from one to dual monitors, I realized a third would be useful, even if there is a diminishing return.
So, I did some research and found the easiest method would be to install a second video card. I just happened to have a little old Radeon X300 Xpress PCIe card laying around and my research seemed to suggest it would be perfectly adequate to run the third monitor for general desktop/graphic needs. It's a 128mb card. So, I popped it in to the third/empty PCIe slot on my motherboard. It was picked up fine by Win7 64-bit Ultimate and I let Windows install a driver so at first try I had the Catalyst drivers for the 4870 card and a default driver for the X300. Device manager correctly identified them too.
On going in to my display properties (windows, not Catalyst CC) it wouldn't detect the third monitor so I decided I should install the X300 specific drivers. I did so and made a bit more progress in that I managed to get the monitor be detected and expand my desktop display to it - everything seemed good.
However, on coming to my system the next morning the third screen was blank/blacked out, without a 'no signal' message. It continues to register the X300 card in device manager correctly, and in display properties if I hit Detect in the displays panel it seems to find an 'undetected display' as the third LCD, but I can't expand the desktop to it and trying to causes the 2nd display to disconnect, leaving me with one (central, primary) display. I can revert back to the dual displays and all is well, but I'm stuck on how to get the third display running again.
I realize this is an odd/unusual setup but I would appreciate any tips or a step-guide approach on troubleshooting this to get it working. I'm quite sure all the hardware pieces are working properly as I've tested each part (LCD) on other systems, etc. I'm presuming it's a driver issue between the vpus and two different driver sets, but I'm not sure.
Thanks in advance, to anyone who can offer help here. I'm imagining that the first logical step might be to completely remove all display drivers and reinstall the latest catalyst drivers and see what happens, but wanted to check in here first.
