an issue with VGA connector.

[antialias1337]

I have a xbox 360 and a hdtv that has a stupid native resolution that should be native to 720p rather than pc spec. For example its 1366x768. While the native resolution is rather good, the 720p ( which is scaled ) is awful, it puts energy in the color brightness and cleaness while the picture is blocky. So I went to get a vga cable that is cheaper than microsofts version. Well, the vga colors are overall warmer than composite, but vga is better due to very little inteference onpar with digital if you ask me. However, i notice something strange, it forms like a transparant copy that you would see in old tv's? like lines will appear to the right of the image that corresponds to the picture being shown.

example:

Image,then to the right of it, about 3-4 times at about the same distance apart each other the same edge of the picture

On compoisite it doesnt do it, neither does it do it when i had my hdtv hooked up to a pc. So i know its not the tv causing it pc mode nor hdtv mode. The xbox 360 i dont think is causing it neither cause when using it on hdtv mode it doesnt happen.

However, I went to a friends house who had a 37 inch LG with the same specs resolution and i dont know if he was using vga or what but his had the problem like 10 times as worse than me.
