Hi,

Can MISTer drive these as a display, basically the "video wall" panels, the HUB75E pinout:

Short answer - no. It would be generally be easier to use an off the shelf driver board that support VGA or HDMI input.
A 320x256 matrix, the minimum probably needed, does not come cheap though ! I am the proud owner of a smaller array that is still a lot of fun, if "blurry" due to down conversion

I have done a lot of experimenting with these - actually the cheapest hobbyist option to drive them if you are handy with coding is to use a Pi or ESP32 to drive the panels using existing code libraries, and then send the Pi digital video in a "dumb" parallel format (basically VGA in a bit parallel GPIO format like R4-G4-B4+hsync+vsync) - that would require a core patch for support I guess - this is basically what things like the RGBtoHDMI Pi adaptor used on Amiga etc does by tapping the pre-DAC pins on the Video chip.
Here is an ESP32 dongle I made for experiments
