    I have a 2011 MBP 15" and I'm curious to know if I can use my HDTV in a dual monitor set up. I know I can mirror my MBP on my HDTV but can I dual monitor??

    Yes, you can use any display (including a TV) as either a mirror of your original screen, or as an extended display.

    I don't see why not... there should be mini-displayport adapters and/or cables to go from it to HDMI, VGA, HDMI, DVI... whatever the HDTV can support.

    You'd want to go into system preferences->displays. Then click the 'arrangement' button. You should see both monitors there, and do not have the 'mirror displays' checkbox checked.

    So for whatever display I want as my "main" display I just drag the menu bar over from one to the other in the system prefs window? Can I go from thunderbolt to HDMI? I just ask cause I've seen many people complain of the dual monitor "issues" in Lion and Mountain Lion.

    yes and yes. I use a minidisplay port to HDMI for connecting to my tv ($7 at monoprice and i saw one for $10 at micro center a couple weeks ago). I run lion and have yet to encounter a problem with extending my desktop. I cannot speak for mountain lion though.

    +1 on all counts.

    Keep in mind the nature of any discussion forum site. You'll see a lot of complaints. People rarely post just to say that everything is working fine.
