2 and 3 accept RGB, only 3 accepts component video. With component video the TV will do Proscan, progressive scan, without the DVD having it, thats why the image will be much better.
Proscan is displaying all the image at once instead of interlacing, odd lines first, than even lines.
I brought the ultimate dvd platinum edition to set up my tv very helpful i thought especially on setting color and brightness and contrast and to check your tv geometry brought mine from amazon
Thanks for all the advice people, it's much appreciated. I may get the ultimate dvd as I suppose if I'm paying money for a tv like this I should make sure it's set up properly. Now I just need the tv to arrive.
