It'd be convenient if you could associate Audio Inputs 1 and 2 with DVI inputs of you choice.
At current the audio has to be muted at source and plays continuously even when not in a presentation, which is an issue when someone plugs a laptop in and doesn't even start presenting but the audio is played!
The following options would be great!
Audio Input 1 - DVI 1 - OFF
DVI 2 - OFF
DVI 3 - ON
DVI 4 - OFF
