I have 2 PC's running windows 7 and dell display manger with my U2913WM, the machines are connected via VGA and a KVM switch. When I reboot the machines or bring them out of hibernation DDM works fine and I can snap windows to the predefined areas as required. However after about 10 or 15 mins the snapping stops and if I click on the icon it tells me please connect a supported Dell monitor
Any ideas please,Im really pleased with the monitor and the ability to snap windows into place is ideal but its annoying it stops working
Remove the KVM from the troubleshooting. Test one computer at a time connected directly to the U2913WM. Does the 10/15 minute snap issue occur?
