My 8350 came in this afternoon and I was able to run new HDMI wires and swap the old L300u (540i max resolution) fairly quickly. I do not have a blu ray player yet but had an old HD-DVD player in closest (ya, lost that bet) to see some high def in action. To be honest, I wasn't wow'd but it looked pretty darn impressive. Played about 30 minutes of Happy Feet and really enjoyed the picture but it was missing something. Then switched to Cinema mode and noticed a sizeble improvement to me... the wow factor was almost there! Made a few more adjustments that were mentioned in Art's review and am now completely satisfied with the purchase!
I then noticed my HD DVD player only did 1080i, wasn't even seeing 1080p image yet. =) With a 139" diag, I'm assuming there will be a decent difference between the two!
Oh, and dynamic mode completely lit up the room. Still need to hook up the OTA box to the projector, but can't wait for some football on this screen. I might be able to get some pictures, but have to get kids to sleep. The pics will of course only be 1080i as well.
