I just got a 4030 installed yesterday, and coming from a 7 year old unprocessed 720p Optoma, I am completely pleased with it so far. Out of the box, and running through an Oppo BDP-103, a quick calibration with the Spears & Munsil Blu-ray showed that all values were only a click or two off. Of course I'll do a more complete calibration after a hundred hours or so. For my situation, the upgrade to the 4030 gave me an obviously noticeable improvement , even to my wife, who couldn't care less about specifics, but got a "Damn, that's a nice picture", which is as good as I'll get. The "free" extra lamp, a Chief ceiling mount, and Epson's 3 year return policy made it worth the slight step down in contrast from the Home Cinema line. Plus, the black case just looks better in my room.
Does anyone else have this unit? Any advice on tweaking it out? How do you like it so far?
