We are using a BARCO-graphics large screen video projector to display the video output of a SUN4/260CXP using a CG5 frame- buffer. Because of the enlargement by the projector we noticed some irritating jitter hitherto unnoticed on the standard 19" color display (made by hitachi, I think) . The dealer attributed the problem to an interaction of the 50Hz powersupply and the 66Hz vsync of the CG5, but he also suggested it might be one of the oscillators on the videoboard. Has anyone experienced similar problems and found a solution? Tjeerd Dijkstra.
