I tried again, this time feeding the pj 720p and the results were slightly different but again not what I expected as normal behavior. All vertical lines were displaying various levels of gray instead of primary or complimentary colors and in the case of primary colors test patterns the horizontal lines were also missing some colors. Check the images below to see what I mean. Personally I'm out of ideas as to why this is happening, since to my recollection I've never seen this before. Note that while viewing normal video material played through the PC everything looks fine. Any ideas? Owners of TW1000 can test this yourselves by downloading Nokia monitor test (it's free) from here: http://www.softpedia.com/get/Multime...tor-Test.shtml I would initially like to rule out a malfunction of my particular sample and then move from there as to the actual reason for this, so if you try this on your Epson, please post your findings.

Edit: Just to get theories started, I think we can safely assume that this has nothing to do with the optics, but is signal processing related, either at the pj or the pc, since in order to display gray lines on primary colors test patterns, the projector would have to add equal amounts of R,G,B where only one of these existed in the original pattern.

Have you tried any other program material? Test dvd's? I wonder if you could make files out of those Nokia test patterns and put them on a CD-RW or DVD+RW and play them through an HDMI connected dvd player and see what happens.
