I have done that with rpi3+vga666 before
and now I did dynamic marquee with single rpi4
same but rpi4 was much easier because of extra hdmi port.

It has done by RiNA from Korean raspigamer forum and I
barely touched any ( just change port for rpi4)

@losernator This is awesome. Where did you purchase the small second screen for the marquee?

@losernator Thanks! This is exactly what I was looking for. Do you have any experience with a screen like this in the Pi 4?

@losernator Really interesting. Actually touch function not really needed if you use it to display Marquees or game artwork: does a "standard display" version exist?

losernator

@UDb23 There is no difference between wide or standard screen.
If you use other standard display, just make your marquee image to that resolution.

@losernator thank you!!

@losernator sorry, "standard" I meant "no touch screen" as it is not needed and should be lower cost.

@losernator Such an awesome idea. I'm running the Official rpi touch screen and it sets the touchscreen as the primary display. Is there a simple modification to the .py that can be made so that it sets the touchscreen as the secondary screen so the gaming happens over the HDMI connection for a pi4?

@tulathron Actually I did test with dsi display, but... I failed.
even though put "display_default_lcd=0" in config.txt, DSI display works always as the default screen
(that option was worked for vga666 dpi display, I don't know why it doesn't work on dsi)
Sorry I can't help.
