Just attatch it, then you can link to it... or you can use a free service like tinypic to upload your pictures...
Try lower values then those... overscan should be adjusted lightly, like 1-10 at most... 1000/1500 is WAY to much! besides that, there is no real "this works for all monitors of this size" it depends ALOT on the make, model and whatnot... just experiment with various values and you should find it, one way would be to use FSD... check it's overscan settings when you found the perfect settings for your tv... and copy them over
