For a GTA04++ there is no need to change the video system. It is capable of driving >75 MHz pixel clock and HDTV resolution. And, a larger display area does not necessarily increase the pixel density. They just become bigger (unless we want to increase the resolution as well). What may need to be changed is the power supply and it may need level shifters. But this is the simplest part in solving the equation. If we get documentation. > - finding a new screen This is also quite tough. Either, they are not available through distribution. Or if they are, a VGA display with touch and 3,5 - 4,5 inch usually costs ~ 100 USD (e.g. Avnet Express, Mouser, ...). I think we all want to have a display with superior-resolution (like iPad) but cheap as water. And available from steady production. And with decent documentation. The last one rules out choosing replacement iPhone 4S displays... > - changing case > > And surprisingly the last one is difficult : you need to design one (CAD > ?) and then either you have a 3D printer to make your own case or you > pay to produce a series of 1000 or more. > > Xavier.
