While it only has options for DP or HDMI input (no Auto select), it seems to actively cycle through the input signals when powering on, resuming from idle, or when there's no signal on either input. The monitor in question doesn't appear to maintain the inactive link (as well as USB connection) when powering off, going idle, or switching input, from what I could find out. Before using a KVM (that I'm swapping between its HDMI and DP inputs that were connected to different places), whenever I switch the active signal, the built-in USB hub power-cycles (devices disconnect then reconnect), and the monitor becomes disconnected to the system connected to the now inactive signal.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
