I recently installed an AMD HD 5550 card into my Intel 915gro MoBo and bought one of those VGA splitter cables as to enable dual display. My primary monitor is working fine, and my secondary monitor is getting a signal through the boot process, but as soon as i get the login splash screen, the secondary monitor goes blank with an error message saying "Cannot Display This Video Mode". My old GPU (GeForce 210) did just fine with the dual display using an HDMI (or is it DVI? the one with multiple pins in a trapezoid) to VGA adapter, but now that same adapter must be old and discrepit because its pin config isn't matching the new HD 5550. Has anyone else faced this kind of Dysfuntion? I have looked into the AMD Catalyst Help and XP Device manager and the secondary monitor isn't being recognized. SIW isn't noticing the second one either. it just says something to the tune of "NetMeeting"
I am on XP 32.
