We have a triplehead2go digital edition that we would like to use with a ATEM 1 M/E video mixer.

We tried setting the th2g to 3x 720 50p and the ATEM to 720 50p, but it didn't work.

This was our setup:

Computer -> TH2G -> Projector
                 -> ATEM -> Projector
                 -> Projector

Connecting the ATEM directly to a computer with the 720 50p works, and the TH2G works also.

Have anyone tried this?


So you set the resolution of your TH2G to 720p50? In that case you don't get 720p on every output but 1/3 of that vertically. You have to set your th2g to 3840x720 so you get three 720p signals on your outputs.

I also recommend using the Matrox App for setting resolution modes instead of the windows/osx display manager.

  • Sorry I was unclear. We set the TH2G to 3x 1280x720/50p = 3840. We did this in the Matrox App and confirmed the resolution and refresh rate in OSX display manager. – Znarkus Aug 18 '14 at 13:11
  • Do you have any hardware at hand to check and confirm the HDMI signal that is coming out the triple head? I can also recommend doing a firmware upgrade if one is available, we often had weird issues with older firmware versions. – PTS Aug 18 '14 at 13:30
  • Thanks for the answers. I might be able to check that in a week or so. I think we have the latest firmware. Do you have any experience with this? – Znarkus Aug 18 '14 at 13:41
  • With the triple head in general? We use it a lot at my company and hate it a lot because the make tons of problems but is the only feasible solution on the market if you need one big high-res renderer for your software. Upgrading the firmware is very easy, you just download an updater software from Maxon and feed it with the latest firmware file from their website. – PTS Aug 18 '14 at 14:00
