Thanks for bringing this subject up again, I have been looking to order one of these to just test around, and as I was going to research the subject, I find this thread where I get a quick answer. It is the next best thing to Indivision.
Since I do hardware builds, I will make some nice box for it. If you have problems figuring out how to wire it, I can make a guide, but it is fairly simple. Or I can do the wiring for you, as long as you pay for parts and shipment back to you.
To make Make it possible to use all screen modes, I figured I would just wire up a VGA cable along side the cable that feeds the board, and connect it to the VGA input. However, I just have to ask, does the board auto switch between inputs, or can you manually select which input that should be used?
