Try TeamViewer on your tablet and a pc connected to your projection system. Connect _to_ the tablet from the pc, and every thing you do on the tablet will mirror on the pc.
Tips for a pleasant XDA:
Search before asking. Someone has likely already asked.
Spell your words completely, and use punctuation. It confuses people when you use "u" and "ur" and "dat", or when you wrongly use "there/their/they're/your/you're".
Be nice. Don't be rude, just move on to another post without leaving a comment. We are not 7 years old.
And PLEASE, do not ask for the "best" anything. We all have our preferences.
