    Recently, my mum bought a 50" Samsung Q9 Plasma TV and I was eager to bring my MBP to her house to test it (will get one in future if everything works the way I want). However I've found that the auto-detection from OSX does not exactly match the resolution from the Samsung TV.

    OSX believes the native resolution of the TV is 1360 x 760 (or something similar) while the actualy resolution of the TV is 1366 x 768. Although only off by a little bit, theres a bit of flashing extra spaces of colored lines on the bottom edge and the right edge, which is very annoying when watching movies etc. Setting the resolution of the TV to anything else works fine without those annoying extra lines/spaces (like 1024 x 768 or 1920 x 1024), however does not look as good.

    Anyone got a way to fix this? Something to tweak the resolution a bit manually, thanks.

    go to system preferences>Displays

    there you can change the resolution displayed on the screen. if in extended desktop view, then the res window for the tv will be on the tv. if in mirrored desktop, then the tv res will be the same as the notebooks display

    Ummm that's not my problem, I know all that. The problem is that either OSX detecting the TV's resolution wrongly or TV didnt send the correct resolution info to my Mac correctly, hence giving me a wrong choice in Systems->Display. I need to manually change the resolution in OSX to match the TV's.

    I found some info here http://pixelmapping.wikispaces.com/Guide+to+1366x768

    However, this only shows you how to do this in Windows XP, which I really don't want to use (as I need to use Frontrow etc with the remote)

    Sounds like your TV does not support what I believe is called 2:3 pulldown. Or something like that.
    When I was shopping for an HD-TV this was an issue a lot of people brought up, and a 2:3 pulldown not being supported by the TV, and a non 1366x768 source were the culprits. Having a tv that can support the proper pulldown (which from what I could tell, were only the higher quality ones) will fix the issue, or obviously having the proper resolution form the source.

    I don't have any real info that can help, BUT I would advise also to check out www.avsforum.com . I know this is a FREQUENTLY talked about issue and the 2:3 pulldown is often a top requirement for people shopping for a tv that will also be connected to a computer.
