Problem: The image is stretched when displaying 16:9 DVD

If the image is still stretched, you will also need to adjust the aspect ratio by referring to the following:

Please select 4:3 aspect ratio type on your DVD player if you are playing a 16:9 DVD.

If you can’t select 4:3 aspect ratio type on your DVD player, please select 4:3 aspect ratio in the on screen menu.
