I found this thread http://help.marseilleinc.com/support/discussions/topics/30000001655. It's apparently not just a 480p issue. I played with some Framemeister settings, and I discovered when my HDMI output was set to 'RGB', instead of 'Auto', it was an issue with every progressive, 60Hz output resolution, except 480p was still the worst. When it was set to 'Auto', it was only an issue with 480p. The picture was stable on 720p and 1080p. The problem is, there's not much use in using it with those higher resolutions. Marseille themselves recommends outputting 480p on the Framemeister. I don't know what to do. There has to be a way to fix this.
damn it !
How can you force 1080p instead of 1440p Luis ? I cannot chose it or can I
yeah same. it doesnt matter which system, it's with any 480p input
