Display problems with my VGX-XL100

[bigwill1001]

I have a Samsung SP-50L 7HX rear projection TV with a resolution of 1280 x 720 and i did have the Vaio set up perfectly, lovely full screen dislay, now unforunatley for some reason unknown to me it has reverted back to a display half the size of the screen and for the life of me cannot seem to remember what i done before to fill the screen perfectly, everything i've done seems to come out cropped.
many thanks, will
