Dual monitor issues on restart??

flynnstone · Dec 29, 2008

I'm currently running two samsung 23" wide screen monitors on an ATI 4870 (windows vista), however every time i restart my PC, the monitors work through the BIOS and boot sequences, however my second display turns off before logging to windows. I have to disconnect the display and plug it back in for it to recognize it.

THis hasnt always been an issue, as they have worked normally after reboot before. Something must have changed in the software to cause this?

Anyone have a fix for this?

I've never ran into that one before, but multi-monitor configs seem to be the most readily breakable video setting.

I would probably try uninstalling your ATI drivers and upgrading to the latest version. When you uninstall, make sure to use Guru3D - Driver Sweeper (Setup) download from Guru3D.com or some similar application to completely clean out the driver settings.

problem solved. In the catalyst software i had to uncheck both DVI settings (Reduce DVI frequency on high-res displays) and ( Alternate DVI operational mode)

Please create a new thread and tell us more about what it going on.

Although it might seem like you have the same problem more than likely it isn't exactly the same.
