I tried to project a video to my laptop from my lenovo tablet. I got the sound. No picture?

Added (1). Maybe there's a setting that I missed?

Okay…

Doesn't work anyway. Laptop isn't designed for that

Laptop is not a monitor.
Tablet is not a computer. You won't be able to transjer video from tablet to monitor or TV.

Which "laptop" and its OS? You can search with Google for how to project from a Lenovo tablet by wireless to an application running on some OS in the laptop. That is all that can be guessed from your details, which were almost nothing.
