No Displayport Signal after "sleep" with Philips 499P KVM switch



I have a Philips 499P monitor with KVM functionality hooked up to a Windows notebook and fedora desktop machine. The switch to Windows always works fine. However, when I’m working on Windows for a few minutes and then I want to switch back to fedora, the monitor mentions that there is no display port signal even though the computer is still running. Somehow it must fall asleep. I haven’t found a way to bring the fedora desktop back to live in those situations other than forcing a reboot. When I immediately switch back and forth there is no issue. I have used another KVM in the past without any issue. Can I do something to prevent this behavior?
