I am assuming this might work?
Code:
/opt/vc/bin/tvservice -M | grep -q "HDMI is attached" && RunCommand

---------- Post updated at 02:04 PM ---------- Previous update was at 01:35 PM ----------

So my bash script would look like this:
Code:
#!/bin/bash 
while : 
do     
/opt/vc/bin/tvservice -M | grep -q "HDMI is attached" && RunCommand 
done

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
