Using a data projector causes pixels to appear jerky

[jamesssydney]

Evening,

I'm using Xscheduler to project a video in time with my sequence. When I play the sequence both the video and pixels begin to look jerky if the video is outputted to my data projector. If I switch the video to output onto a regular (1920x1080) monitor as an example everything appears to work fine.

Resolution of the data projector is 3840 x 2160 connected via a HDMI cable

Have you tried to reduce the resolution on the projector to 1920 x 1080 as a test?

I couldn't figure how to change the resolution on the projector. As a work around I duplicated the monitor and projector together and that worked a treat!
