Currently using my HDMI KVM to connect to some spare TV I have until I get a proper PC monitor. The TV is an Insignia NS-24L120A13, which typicalyl defaults to 1080p 60Hz. This TV has no option to stay awake indefinitely, and turns off after about an hour without use.
Currently I have two Linux and one Windows machines plugged in through the KVM. The Linux machines work perfectly fine, but the Windows one has issues with working again after this the screen turns off after an hour without use.
The actual issue is that afterturnign the TV screen back on, no amount of moving the mouse or using the keyboard will restore the display of the Windows machine. I tried unplugging & replugging the KB & mouse, but to no avail. The only fix is for me to hold button on the back of the KVM for 10 seconds to rescan for the EDID again, then switch to another input on the KVM, then back to the Windows machine’s input.
Is there no way to prevent this from happening? My next best bet is to replace this TV with a proper PC monitor that has proper EDID settings and the ability to control the timeout for automatically turning being turn off, but I’m hoping there’s at least a temporary workaround for the time being.
