So I installed Nova launcher and was looking through the activities from all system and installed apps and found two interesting ones. One is HDMI settings; 
You can add it by going to Activities > HDMI and finally selecting HDMIsettings..
I have no idea if this works or not so I'm hoping someone with an MHL adapter could try?
Another interesting app I found is a Desk Dock which is pretty cool;


It can be found by going to Activities > Desk Dock and finally selecting common.DeskDock
Thought the community would find these interesting (hoping no one else has posted about these before!)
