It’s difficult to make recommendations, since single quantities of these displays are usually sourced from EBay which I don’t personally use and I can’t vouch for any specific seller.
However I’ve found several kits like this on EBay which closely match the 12.1, 1024x768 display we managed to get a small quantity of:
Obviously I can make no guarantee that these will work with the Pi, or fit, or even turn up, but they’re out there!
Basically, the checklist is:
- Comes with a driver board
- is HDMI-capable
- is 4:3 aspect ratio, ideally: 12.1" at 1024*768 fits this nicely
- is small enough to fit in the cabinet ( I forget what the maximum dimensions are )
It’s easy enough to find widescreen panels, but the larger ones tend to be too wide for the cabinet and you’re going to have to windowbox them to get the right aspect ratio out of your games, so it’s all wasted space.
