if this is an issue it would be considered hardware. Take it in. Nothing can be done here on line.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment

Make an appointment for a "hardware issue"

to reinforce what lerydouglas already said:

There is no standard setup that has additional data from another device to the right or left ON the main display, projector or no projector.

What you are showing appears to be a failure in the display module itself, which is producing arbitrary colored strip and a black area along the right edge of the display.

The only other possibility is if you use split screen, and that draws a Black dividing line.
