+## Getting Display to work
+
+I am trying to get the Blackmagic Ultrastudio Express video capture card working with PAL over HDMI
+
+I had it working with the desktop environment once but struggled ever since.
+
+Links
+
+* Extensive list of details on diplsay and the pi: https://www.improwis.com/projects/hw_RaspberryPiSPIdisplays/
+
+
+
+##  Notes from the CLI
+
+Ultrastudio Express' EDID is:
+device_name=HXA-BMD_HDMI
+
+
+```
+# Get the edid info:
+tvservice -d /tmp/edid
+
+# Read the edid info:
+edidparser /tmp/edid 
+
+# preferred resolution
+edidparser /tmp/edid | grep preferred
+
+# supposedly this refreshes the screen buffer
+fbset -depth 8 && fbset -depth 16
+# maybe to 8 bit for PAL
+fbset -depth 16 && fbset -depth 8
+```
+
+
+Did not resolve the BMD card to recognise 576i or p over HDMI
+
+For composite there is no matching cable,
+
+## Resolution
+
+Using 720p and stretch window then anamorphic conversion of the BMD UltraStudio Express to convert it back to PAL 4:3. Basically 720p down to SD; then use PAL 625i50 preset while capturing.
+
+### The Video Commands
+
+```
+
+cvlc v4l2:///dev/video0 :v4l2-width=720 :v4l2-height=576 :input-slave="alsa://hw:CARD=Cx231xxAudio" --aspect-ratio=4:3 --crop=4:3 --fullscreen
