but soon this will be implemented into Pixivisor for the PC/MAC/LINUX version to be able to receive the signal as well as sending the signal so in this case you can use screen grabbing software for making videos without extra cables and set ups...
Another thing as we are talking about glitchy video here is to just record the screen directly with whatever you have to record with.
If all this is confusing to you because you have not heard about Pixivisor you can go here:
