Hello,

I have a Pi400 that I was trying to get set up with the HyperPixel no touch display. I have it connected by a ribbon cable and have done everything in the setup with a clean Raspian Install. I commented out dtoverlay and I am still not getting any display, just the backlight. Previously I was able to get it to display for ~1 second of the startup, but then it vanished.  
I am using the most recent release of Raspian should I roll back or is there anything else I can do in config.txt?

Thank you,  
Chris
