It helps, but you can't do miracles tweaking your tv settings. If the developer uses Quincunx AA, you'll going to have blurry images. It has it's advantages over 2xAA, as an indirect texture filtering and transparent texture antialiasing effect that normal multisampling AA doesn't have, but I don't think it must be used due to the overall blurriness it produces.
