Unstable Eyefinity 3D Active Glasses Sync

Recently implemented 3D Eyefinity configuration (see whyme466 Jan 2013 comments at, for much more information). Unfortunately, it appears that Stereo (L/R pair) frames are not being properly synchronized by Eyefinity. The Active Glasses sync signal is NOT ALIGNED on the 3 HDTVs, even though they are in Eyefinity sync (AMD probably not syncing start of full L/R frame sequence, just individual frames instead). Setting desktop to 1080p24 and enabling Vsync did not help. Good 3D video is rarely shown on all 3 screens simultaneously (never stable, drifts between 3D and merged L/R 2D signal), but any one of the 3 displays can be made to work correctly by simply forcing the Active glasses to sync with that specific display. How can this sync problem be resolved?
