Thank you for posting to the Answers Forums!! We are here to help. I see how this could be a frustrating situation for you to encounter when dealing with the Slingbox. Here is an article that I could recommend to attempt to resolve this issue.
- When you try to stream, you see giant black bars on the left and right. The aspect ratio is all wrong. What's going on?
Also have you tried to hook up another AV device to the Slingbox to see if you still have the same issue?
Let us know the results thank you for your post.
