Finally following up on my own, lonely, unanswered message, in case anyone finds it in the archive and has a similar problem.
After weeks of running at 800x600 because I was too busy or lazy to spend time on the problem, I visited the NEC/Mitsubishi site and read their troubleshooting guide. It recommends a shielded video cable. That fixed it. Mind you, the panel's cable is permanently attached, but adding a six-foot shielded extension solved the problem. I speculate that the original unshielded cable was hanging too close to the fan motor, but that's a pure guess. In any case, problem solved. -- Carl Fink [EMAIL PROTECTED] Jabootu's Minister of Proofreading http://www.jabootu.com -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
