KVM Double monitor problem

Posted on 2011-03-20
Last Modified: 2013-11-08
So I have a PC and a Laptop connected to a KVM. The laptop is a ProBook 6455b with and ATI card.

I recently updated the ATI driver and started having the following problem, when I change the KVM to control the PC the laptop detects I unplugged the monitor and changes the configuration to single screen, when I switch back the KVM to the laptop it switches back to double screen.

So everytime I go work on the PC all my windows get switched to single screen, and when I get back I need to reacommodate.

This wasn't happening with the previous driver, is there a way to avoid this from happening?.

Thanks. I'm running Win 7 Ultimate.

Go into your control panel / display settings / adjust resolution.  Try the options under "Multiple Displays".

If that doesn't work, I would say roll back to the previous driver.

Actually I don't have any problems with the configuration. I just wanted it to hold the configuration when I go to the Desktop PC on the KVM.

So it was working as you wanted with the previous driver?  I would say roll back to the previous driver.

Feels strange to say it, but the Windows 7 provided driver for older ATi cards is actually more useful for what you wish to do than the AMD supplied one.

Uninstall the ATi driver and catalyst software, reboot and use the Windows 7 one.

I actually tough that. But the driver is attached to the sound driver, don't really understand why, so everytime I update the sound and video gets updated. And I can't keep on rolling it back.

I am on a corporate network and we have and auto driver updated.

I'm marking this as the solution for most cases. I will need to find a way to stop the autoupdater run by my company.
