TV not working when extending/duplicating from my main computer monitor when NOT set to?

Hi,

When I try to duplicate/extend my desktop on my main monitor to my TV, it will ONLY work if it's on the lowest screen resolution which is 1024 x 768. Otherwise, when I try using a higher screen resolution for TV secondary on extend/duplicate, it WON'T work...I don't know why, and it's really annoying.

    because the TV doesn't support higher resolution that's why!
