Display Screen

how can I fix that problem?

Hi @Ser83637, sorry that you're running into this BIOS display issue.

I think this might be because BIOS resolutions tend to be different from typical wide-screen resolutions.

Can you try changing your TinyPilot's EDID? This will give your TinyPilot additional display settings that may improve compatibility with the BIOS.

First, SSH into your TinyPilot and then run the following commands (copy & paste):

EDID="/home/ustreamer/edids/tc358743-edid.hex"

# Back up original EDID
cp --no-clobber "${EDID}" ~/tc358743-edid.hex.bak

# Set the new EDID
echo -ne "" | sudo tee "${EDID}" && \
  echo '00ffffffffffff0052628888008888882d1e0103' | sudo tee -a "${EDID}" && \
  echo '800000781aee91a3544c99260f50547fef8081c0' | sudo tee -a "${EDID}" && \
  echo '8140810081809500a9c081406140271f80f07138' | sudo tee -a "${EDID}" && \
  echo '164038c0350040442100001eec2c80a070381a40' | sudo tee -a "${EDID}" && \
  echo '3020350040442100001e000000fc0054696e7950' | sudo tee -a "${EDID}" && \
  echo '696c6f740a202020000000fd003b3d0f2e100000' | sudo tee -a "${EDID}" && \
  echo '000000000000014702031c734c010204139f2021' | sudo tee -a "${EDID}" && \
  echo '223c3d3e3c2066030c00300080e2007f00000000' | sudo tee -a "${EDID}" && \
  echo '0000000000000000000000000000000000000000' | sudo tee -a "${EDID}" && \
  echo '0000000000000000000000000000000000000000' | sudo tee -a "${EDID}" && \
  echo '0000000000000000000000000000000000000000' | sudo tee -a "${EDID}" && \
  echo '0000000000000000000000000000000000000000' | sudo tee -a "${EDID}" && \
  echo '0000000000000000000000000000006b' | sudo tee -a "${EDID}" && \
  sudo v4l2-ctl --device=/dev/video0 --set-edid=file="${EDID}" --fix-edid-checksums

If you need to revert to the default EDID, you can run the following commands:

EDID="/home/ustreamer/edids/tc358743-edid.hex"
sudo cp ~/tc358743-edid.hex.bak "${EDID}" && \
  sudo chown ustreamer:ustreamer "${EDID}" && \
  sudo v4l2-ctl --device=/dev/video0 --set-edid=file="${EDID}" --fix-edid-checksums

Please let me know if that helps!
