The VB, is very noticealbe on the DALITE HIGH POWER, (2.8 GAIN)with the PANY floor mounted. My best guess is I am getting something like 2, to 2.5 gain, in that location. Is very noticeable on light backgrounds. Not so much during pans, but just a very bright , light, back ground, you can see it. Having just said this, I can see how some might say it is so slight, why worry about it,etc. however when your used to viewing other projectors that do not have this issue, well one does worry. I do have to say last night, i sensed I wasnt seeing the VB, as bad as the first night, nor, quite as bad as when I first turned it on last night. Seems to me, I remember some posts on the long 700 thread that a lot of those who saw these issues with a new 700, didn't notice it as much, after the projector started to get some hours on it. Anyway, perhaps that is what I am experiencing at the moment. To put this in clear perspective, the VB, I am seeing is not so bad that you are constantly taken out enjoying what ever is on at the time. It's kind of just "vaguely" there.
Also need to add, the overall quailty of this unit, is quite good, even with the VB, I am currently seeing. Overall "look" of this unit is very pleasing, and I would say at this early stage, the ability to go to "BLACK", is about on a par with the SONY HS51. Unit does need some calibration however. Out of the box and with CINEMA 2 being used, and everything on default, the black level was way to high(or not low enough,semantics?). Black bars, above and below a 2:35 film, were not even remotely dark grey, let alone something near black. They were almost a bright grey!. Had to drop the brightness down to -21, and kick contrast up to 10. At those settings, looks pretty impressive at the moment, and with excellent shadow details.Blacks still a bit to bright, however I want to play around with the gamma settings first, to see what that does.
In closing, if I can get rid of the VB this will be one "killer projector" for not to much money. I suspect when 1080P chips finally hit with the D5 chip from EPSON(probably another year or so out),and with another generation of tweaking by PANASONIC to make these projectors more uniform (READ: VB, FREE !), we will have on our hands one, very, very, sweet projector for not to much money. Of course the NE PLUS ULTRA of 1080P projectors, will still probably come from DLP, however for significant coin, to say the least .
