I have had my projector since October and I think there was a post by others on this once before (can't find it now), but I am seeing it more ofter due to watching more sports (with the text always on the screen) than movies with the NHL playoffs, baseball starting and the NFL draft:EDIT: I found the post here
: pulsating focus
My projector seems to change sharpness from razor sharp to slightly defocused on the text on these channels. It will come back around to razor sharp again then a few minutes later, I will see the text as slightly blurry. I don't notice it during a movie usually, but I did see it during a foreign movie with subtitles the other day.
Is this something others are seeing and does it happen to be addressed by the latest firmware to anyone's knowledge? (oleus, I see you are one of those who posted, did the firmware help this issue?)
I will also say that for some reason, my unit seems to be sharper on a native 720P channel than a native 1080i channel, which is odd for a 1080P display.
Now that I have finally moved on from the rainbow issues I had early on, I really love the projector, but this is an interesting development that I would like to get to the bottom of.
