I wish the PJ had more than just a green grid test pattern. I will have to look for my old Avia dvd I guess. I found most of my problems with getting the picture in focus surround this text halo, I keep trying to focus out the halo vs keeping the menu text sharp. Normal hdtv/bluray looks perfect, no ringing or halo on sports tickers, credits, etc. Could it just be the menus?
When I first installed my 4000, I also noticed smearing/halo similar to the image posted. This only occurred at the bottom edge of the screen, where the Zoom/Focus submenu is. My assumption was this was an optical issue, since it didn't occur at the top or center of the screen, where the light path will be more through the center of the lens.
Initially my projector was mounted about an inch above the top of the screen. I lowered it to two inches below the top, and redid the 16:9 and 2.35 lens memory settings. This mostly eliminated the text smearing at the very bottom.
You really can't expect the lens to be perfect at the edges. Look at the edges of a digital camera image when zoomed out fully and you'll see the same thing.
Also, although the smearing may look bad close up, it's not something you will notice watching a movie from normal viewing distance, no matter how hard you look.
