Feature request: Add a real video toggle on the KVM for HDR setups

KVM
1

Hi everyone,

I’d like to suggest adding a proper video on/off toggle to the KVM. When video is off, the KVM should fully disconnect the display so Windows thinks it’s unplugged. This is important because Windows will disable HDR on the main monitor if the KVM screen is still detected.

This would work better than using EDID emulators or HDMI splitters, because those usually keep the display “alive,” which causes HDR issues.

So the idea is simple:

  • Video ON → monitor connects normally

  • Video OFF → Windows thinks it’s unplugged

This would make HDR setups with duplicate displays way easier to manage.

It seems not possible; the HDMI chip's power control was not designed into the hardware from the start.At least not in RM1

Keeping the KVM video alive also causes problems with windows continuously discovering then disconnecting the KVM monitor if you have your graphics card to output on Monitor 1 only. I do this as I cannot duplicate the screen due to the KVM not supporting my resolution at 60hz. If I extend the screen that is fine and keeps windows happy but then the mouse pointer sometimes disappears onto the extend display. Easy enough to get it back but annoying behavior. A real Video toggle would solve this issue as well.
