Query: Works well when both monitors are on

Pros: The switch works fine, and I like the attached USB hub switch and audio switch, which can either be linked with the computer switching, or unlinked and "left behind" with one computer while switching to the other. Video and audio quality are fine. Works at 1920x1280.Con: If both computers are on with live displays, it works fine. If one or other computers is completely off, or is disconnected, it works fine with the other computer. But if you are working on computer-A for 15 minutes, and computer-B decides to put its display in power-save mode, the switch erroneously routes the power-save to the monitor, blanking it out. Naturally, it requires switching the KVM to computer-B, jiggling the mouse to awaken the screen, and then switching back to computer-A to resume work. It's symmetrical - working on computer-B is equally troubled when computer-A decides to power-save.
