Windows 10 graphics issue with KVM

I have purchased a new Windows 10 Pro Dell PC for my boss, which he wants to use alongside a Windows 7 Pro one with a KVM switch. The switch previously had an XP machine at this point and has worked OK before. Windows 10 seems fine until he has switched the KVM to the Win 7 then back to Win 10. A message is displayed that the monitor is not able to display the picture at this frequency, set it to 1680 * 1050 @ 60 Hz. The PC has to be rebooted to exit the message. When taken off the KVM the computer works perfectly. If left in safe mode the computer is OK after the KVM switches, but not in normal mode. I have tried to set the display setting to the given value in Safe Mode, but it still seems to fail when back in normal mode. It is a Dell monitor, the other PC is an old Dell one, the KVM is a StarTech one, really small. The PC has Intel on board graphics. He still has VGA on the KVM, so I am using an adapter from VGA to Display port for the new PC. The old PC plugs in as VGA. How can I get around the problem please?

It seems like the problem is with the StarTech KVM. Does it support Windows 10 or the GPU on the graphics card? Check the StarTech website and see if they have any firmware updates for the KVM. Otherwise, you may need to get a KVM  that is compatible with Win 10

Thanks for that, it never occurred to me that the KVM switch could be incompatible!

The KVM is quite old, so I have ordered a new one which is definitely compatible with Windows 10 and the screen resolution that he wants to use. Thanks for the insight!
