remote video (control and view) fails when disconneting KVM

I have 6 PCs connected to a KVM (Keyboard, Video, Mouse switch) and all are running remote utilities host.

I can connect and disconnect the KVM to all of them and maintain RUT video except one.

An HP ProDesk G9 SFF. It is running a video card (I can't check the type right now).

On this one host, the steps to reproduce are:

1. connect to host via KVM.
2. connect to host via RUT
3. disconnect KVM

Result: the RUT video freezes, the mouse does not move, and I can't control anything. If I disconnect and reconnect it hangs on the globe-map screen.

All other RUT functions work on this host with KVM disconnected: login, terminal, file transfer, remote execution (eg notepad.exe). Only local viewer video doesn't work.

When I reconnect KVM, remote RUT video works again.

I suspect the problem is that when the 'V' of the KVM is disconnected, that the graphics card changes something and RUT can't understand/find that.

Hello John,

Thank you for your message.

Yes, this issue definitely can be caused by the graphics card changes. What we can recommend here is to enable the Use Legacy Capture Mode feature if you haven't done so yet or use a HDMI dummy plug in adapter - this is what tends to help with similar issues related to headless Host machines.

Let us know if you have more questions.
