It's hard to tell from the pictures... How well focused is your projector? It's pretty darn difficult to get it right without some kind of aid. I use a camera with 36x optical zoom. If you don't have something to help you, you have to put the PJ out of focus. Now start focusing the PJ, moving the focus ring like 2mm at a time. Move it 2mm, check your focus at the screen. Move it another 2mm, run to the screen and check it again. Get as much of the screen in focus as possible. You can use the focus pattern on the remote, or use the pattern in your pics, the one with the Red, Green Blue lines. Your convergence looks good. You seem to have a bit of flare, and at least the blue pixels seem to be out of focus. Also, it could be just the pic, but it looks to me like the right side of your screen has a pink tint?
First, verify your focus is as good as you can get. THEN check convergence, Do the focus with convergence adjustment off. If your pixels are out of convergence by more than 1 pixel, I'd return your PJ. If they're within 1 pixel you can use the adjustment. Bear in mind that Epson considers 1.5 pixels good enough.
Then check flare. You are going to have minor issues. What you don't want is issues that are visible from your seated position. A pink hue to one side of the screen is bad. Convergence issues that you can see on the menus or patterns from your seat are bad. Enough flare to make text look fuzzy is bad.
There's nothing "bad" about LCD technology, but it does have limitations. Pixel fill is worse than on the Sony HW50. If you sit closer than 1.1 x Screen width, I think you'll want to go Sony or a DLP. If you sit at 1.1 x Screen width or greater, The minor pixel limitations of LCD should not be visible. Don't expect that LCD PJs will be perfect at the pixel level. DO expect that these limitations should not be visible from your seat. If they are, and you're 1.1 x screen width or better away from the screen, your PJ has a problem that needs fixing.
