Vga out worked out of the box on my 52 inch Plasma TV in the Motorcycle Shop before the TV died.
No keycode was needed to switch to vga because is was a Desktop Machine .
If I was you. I'd look for the Mac Manual for switching to external vga on your laptop 1st.
The search the internet for getting that hotkey working in mint if it does not work out of the box. The TV has to be set to the right channel also to accept PC
input. The TV manual online should tell you how to do that.
