Screen Output to Projector and Another Computer Recording the Screen I'll be recording some conference talks/tutorials in a couple of weeks and needed a way to capture the presenter screen without requiring them to install additional software on their machine.  The presenter would typically output their laptop/device data to a projector.  However, in addition to the projector I need to capture the output that is going to the projector to another machine for editing and creating the conference talk videos.

As I mentioned, installing software on the presentation laptop is not preferred.  In the past I've just pointed a camera at the projector and recorded that, but that didn't end up being as good a quality that I needed.

Thanks in advance.
What I have done in the past is to use a DA on the output of the laptop. One output to the projector and another one to the recording device. 

The problem I faced afterwords is that in the chain I had a video switcher and, since we recorded both audio and video, the audio was noticeable ahead. That's a problem if you also have a camera recording the presenter, but not so much if you are only recording the output of the laptop. Later I fixed it in a simple video editor, no big deal, but next time I am using an audio delay in line.
