On most projectors there's a feature that lets you "freeze" the currently displayed image so that the computer connected to it can do something else while still keeping that image up. I was wondering if there was a way to create some HDMI pass through that lets you do the same. I understand that this feature does exist on some hi-fi equipment, but I don't wish to spend $3k for one simple function.
Am I just not finding it or does something like this not exist?
All I want is some kind of "freeze" feature that works through HDMI.
I understand Macs can already do something quite similar to this, and with Windows you can just extend your desktop to the second display, however I do not want to use the extend for this use. If there is some kind of way for software to do this, please do tell. The computer I'm aiming to do this is on is running Windows 7 and it needs to either run through software or HDMI.
