I was able to create a border around my screen and the tape does a very good job of killing all reflections when overscanning.

Also does a great job of hiding the over spill from the projector.

While it stayed on the screen this tape did a good job of absorbing the over spill of light from my projector

Does a great job of framing in your screen

Black duct tape did a much better job, doesn’t collect lint and is still performing.
