I have an electronic musical instrument that has an embedded PC inside it. It can be controlled via a USB mouse and settings viewed by connecting a monitor to the VGA port. I'd rather use my iPad for this job. I can't load any software into the embedded PC, so that is not an option, but I can connect hardware to the USB port (as long as the H/W does not need special drivers installed). I just need to be able to use the iPad screen as a VGA monitor and it would be a bonus to be able to use the touch screen as a mouse. Any ideas how to achieve this? Whever I search for VGA and iPads, the topics deal with connecting a montor to the iPad, not using the iPad as a monitor.
