Hi there!
Is it possible to prevent a 460-MX 3 display form switching back automatically to MagicInfo source, when no other input source is attached?
One of our displays is located in our conference room and normally displays MagicInfo contents. MagicInfo is also its start-up source. Sometimes people get distracted by the changing contents during a meeting. We tried to change source so that nothing would be displayed (no other source connected), but the display keeps switching back to MagicInfo.
Is there any possibility to prevent switching back or any key combination to just "turn the display black"? I know, turning the display off also works, but that wasn't the kind of solution I'm searching for...

... but many it's our only possible option?
Thanks a lot in advance!
Sabrina
