Hi,

did anyone get the "solution" for this problem from sbabboud?

I don't understand why he wouldn't post it here but still say he found it...

Ok, I installed the newest version of NanoDLP on a Raspberry 3 and it works now.

I'm not sure if this is because of changes in NanoDLP or Raspi-Firmware.

Here is my working config.txt

# and your display can output without overscan

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
