Interestingly you can get out DPI display signal from GPIO pins. Adafruit is using this technique with their Kippah display, giving you fully accelerated display signal (unlike those crappy low-fps-low-res framebuffer driven GPIO displays).
- duskwuff 11y agoCorrect. My understanding is that trick was made possible by design -- one of their engineers specifically chose pins to bring out to the GPIO header to facilitate it. I've seen some variants on the "Kippah" to directly drive VGA.
