Thanks! That makes sense
I have never seen a 3.2 inch screen with HDMI input. It might not even exist due to the smaller resolution. So I was thinking I was going to need to do something on an fpga to convert HDMI to SPI or whatever interface the display I end up choosing uses.
For emulators like Drastic, if I have to go the fpga route (which I hope I do not) I might end up trying to copy only a portion of the framebuffer on the fpga and do the same on the fbcp for the other screen. This hopefully allows me to split the image without additional processing on the Pi.
Edit: it looks like they exist now: https://www.waveshare.com/product/displa...-lcd-h.htm
