Hi, I'm fairly new to home cinema although I have been an audio enthusiast for years. I recently installed a custom home cinema and chose the Harman Kardon DVD30 and Infocus 5700 DLP projector. I have used the system on Interlaced scan for approx. 2 months before realising that I had never selected progressive scan (even electronic engineers get forgetful sometimes!) Interlaced reproduction was and still is excellent with the above equipment, so naturally my heart raced when I switched to progressive scan. What a disappointment! Whilst projector and dvd player performed superbly with the factory settings on interlaced, progressive threw out the brightness, contrast and colour balance by a mile! The picture was appalling. I've since spent hours setting up the projector to give a decent picture, although I have a suspicion that there may be either an equipment problem or something I have overlooked. I contacted Infocus support who replied within 30 minutes, but suggested that the problem was being caused by the dvd player. Has anyone else had this experience or any idea why switching from interlaced to progessive should alter the balance so dramatically? I'm using component video connections.
