Hi there. I have two monitors. An Acer that's just vga and a Gateway that has both vga and dvi. When I try to plug the Gateway into my ASUS HD7770-DC-1GD5-V2 via dvi, Windows doesn't recognize it. Which is weird because when I start my computer, the whole boot process is visible on the monitor up until the point when Windows loads. I have messed around with uninstalling and reinstalling the drivers and even trying older versions of the drivers, but nothing worked. I actually think that the problem might be with the drivers themselves. When the drivers aren't installed, the Gateway is recognized as a generic monitor but doesn't allow for extending the desktop. Once I install the drivers, the monitor is no longer recognized. Does anyone know how to fix this problem? Any help would be greatly appreciated.
