That might depend on the software in your projector. Since you didn't tell anything about that, it's impossible to answer.
How about using a PC/laptop for running the software and a projector for projecting the image? You can put the PC in a more accessable place. That's the "divide and conquer" principle.
Can anyone help me devise a way to auto-loop on a mini projector even when the projector is switched off and back on? For a gallery work, I need a single switch to switch on the mini projector, but the content must loop automatically thereafter without requiring menu navigation to do so. This is because the projector is in a hard to reach, hard to read place making menu navigation very difficult, Is there mini player or other devise that can assist? Or can I bypass the menu setting to make it permanently loop somehow? Thank you
