Any idea on how (if at all) to stop the green output transparency from showing on projector screen? Changing it to black I know works...but we are using the green output for chroma keying on livestream output.

Hi Mike! The transparency will be shown when there is no foreground object or background to hide it. To solve this issue, first set your projector output to show Slides and set the background of your choice.

Then for the live stream, use a dedicated output set to Slides (Foreground Only). This way your projector will show a background, while the live stream will receive a signal with only the foreground object (text in your case) with the selected transparency behind it. 

See the section "Send Only Overlays to Live Stream" in this support article for reference:

Hi Slav,

Thanks for your response. Appreciate it. However, that is exactly what we have done. The Green Output from Transparency still show’s through as a green bar at the very top and bottom of the main projector output (even with foreground objects on the slides). Its like the transparency output extends beyond the 16:9 size of the slides. Does that make sense?

It sounds like maybe your projector is not actually projecting 16:9 but actually something else. Maybe 16:10? Could you see if it’s a setting you could change there?

Right now the output transparency color affects all the outputs so we don’t have a way to turn it off for one output. This is normally not an issue if the slides aspect ratio matches the screen it is on.

Hi Jordan,

Thanks again. I'll have another look at the projector settings and see if something is going on there.

Blessings, Mike.
