We upgraded our sanctuary as well with he ATEM TVS. My solution for the Powerpoint laptop into projector/monitor TV/input into ATEM is a VGA splitter/amplifier (from Shinybow):

I connect the Powerpoint laptop into the input of the splitter and send the output three ways: 1. to a Kramer presentation switcher/scaler (older model no longer sold), which in turn sends the signal to the ceiling-mounted projector. Into the presentation swicher/scaler we also connect a DVD/BluRay player. 2. via a 50′ VGA cable to a 32″ TV to the front of the church (where the speakers present and where they can see the TV up-close for monitoring). I convert the VGA signal at the TV with this:

The TV image is crystal-clear, detailed and everyone who sees the image on the TV is amazed. 3. I just purchased a Kramer VGA to HD-SDI converter/scaler:

This unit will set you back a few bills. HD-SDI is not cheap, but I hope is the answer to getting a high-quality laptop VGA image into the ATEM switch.

If you are interested to see how it works, I can post my comments back here after I have a chance to test it this weekend in a live streaming scenario.
