Hi Guys had my new 42lM660T delivered yesterday anyway having hooked it up to my wall mount in my bedroom noticed i had some ghosting from the 3D so I realized the TV was mounted to far up and needed to come down 6 to 8 inches.
So looked for some 3D test cards so i could judge just how far it needed to come down.
Noticed this youtube clip where a guy uses a test jpg with the indian test pattern on the right and a black on the left,having searched for this image and not finding one i quickly mocked one up.
Take a look at the youtube clip on how to use it, you can also use the 3D depth control to align the horizontal images perfectly.
Image attached for you guys.
