I have Radeon 5700 XT, recently I've bought a KVM switch. When I connect monitor via KVM switch I see flickering every few seconds. In atikmdag_dce.log I see the following messages:
[+00:021:924] [Conn_Hotplug] [DP-3] - Connected

When I connect monitor directly to the video card there are no such messages (no Conn_LinkLoss). There is no such a problem on another machine with Intel video card.
What can I do to resolve the issue?
