- ## Your HDMI monitor may support only a limited set of formats. To find out
- ## which formats are supported, use the following method.
- ## 1) Set the output format to VGA 60Hz (hdmi_group=1 hdmi_mode=1) and boot up
- ## the Raspberry Pi
- ## 2) Enter the following command to give a list of CEA supported modes
- ## /opt/vc/bin/tvservice -m CEA
- ## 3) Enter the following command to give a list of DMT supported modes
- ## /opt/vc/bin/tvservice -m DMT
- ## 4) Enter the following command to show your current state
- ## /opt/vc/bin/tvservice -s
- ## 5) Enter the following commands to dump more detailed information from your
- ## monitor
- ## /opt/vc/bin/tvservice -d edid.dat
- ## /opt/vc/bin/edidparser edid.dat
