Can anyone comment on their experience with a 120 inch screen and the Panasonic PT AE 3000 projector.


I am trying to determine if the Projector can effectively handle a Grandview120 inch white screen 1.0 gain. (or similar).

It depends. If you use the shortest possible throw, you'll squeak in with a watchable brightness (19Fl) in a completely dark room. (assuming of course that your calibration settings get you what the calculator is assuming for brightness)


Some people are happy with that level of brightness. I think I would find it too dim.

Art's Projector Reviews gives these numbers -

Cinema 1= 402 @ 6519K

Cinema 2= 391 @ 7021K

Cinema 3= 422 @ 8051K

Normal= 936 @ 8646K

Dynamic= 1144 @ 7455K, 1261 at full zoom out, 760 at full zoom in

Color 1= 461 @ 6742K

Color 2= 539 @ 7457K

402 lumens on a 120" screen of unity gain gives you only 9.5 foot lamberts to begin with. Way too low.

Sorry guys, one follow up question.


The AE3000 brightness doubles when operating in "normal mode". Given that I would almost exclusively use it for movie watching, Should I use the brightness values from the Cinema modes instead?


(would your recommend watching movies in normal mode)

I haven't seen the AE3000, but generally the cinema modes give the best color balance for movies on most projectors. You may want to consider a smaller screen, a gain screen, or both.

I guess I am one of those dim loving people then. My HD70 in low bulb mode, is about 16FL at 12'6" from the 100" diag 16:9 screen, cinema mode. Dark room, and I am completely happy with the brightness. But I don't know if the calculator online assumes the projector is at it's max brightness? Regardless, I am happy with the brightness of my 1.0 gain screen with bulb in low, cinema mode, at 100". And the AE3000 is brighter.


If I had the AE3000, then my same 100" screen based on that calculator would be 21FL.


So with the AE3000 giving 19FL at 120" 16:9 1.0 gain at 11'10" away. I would be more than happy. It would be a bigger and brighter image than I have now.


Anyway, just not sure I agree with 19FL being dim and barely watchable. At least in a dark room.


Sure, if you don't have light control... it's a huge issue. But if you can black out the room in broad day light like I have, then I see the AE3000 as a great unit at 120" 16:9 1.0 gain image size.


I am thinking of getting the AE3000, though I like my DLP and would like to stick with DLP. But my next setup will be a CIH 1080p setup with no HE lens. So far it looks like the AE3000 is my only option for that type of setup.

Agree on all points.


I don't recommend using Projector Cental's screen calculator as a tool for screen brightness. You need real numbers from a qualifed reviewer and a screen calculator. The PC calculator doesn't say how many lumens they are basing the estimates on - torch mode? Cinema 1 mode?


Email me if you need an Excel screen calculator and I'll send you one.
