Default Rom thats work whid Mhl-adapter.

Hey.

Installed kitkat 4.4.4 cm-11. "Stable"
Far from satisfied with most things
Could use some quick help with a rom that works with an MHL adapter. "Hdmi"
I want to se on Theodor TV what i se on my sgs2.
And it's just as easy to install new ROM if it is to downgrade to?
What do I need to consider?
NOTE uses me never out of computers.
I use the very simple program "ODIN mobile Pro"
Has enough been surfing around on the cell phone a total of 4-5 hours just for a solution.
But now I give up and ask for help.
Any help is welcome.
