Ah, great thanks! 'perl -pi -e' for in place editing sounds like
the tool. Something like:
cat > mylyx <<EOF
#!/bin/sh
case $DISPLAY in
mon1) ZOOM=200 ;;
mon2) ZOOM=100 ;;
esac
perl -pi -e "s/(\\screen_zoom )\d+/\$1 $ZOOM/" $HOME/.lyx/preferences
exec lyx "$@"
EOF
should do it. Thanks for the idea!
