Hello!

After years of planning on foot dragging we have finally started our home theater project. We will have a dedicated room for as our home theater with no windows. After some research and lot of reading I have decided on Panasonic AE8000. Now comes the hard and confusing part of deciding on the screen. We would be watching mostly movies, but with occasional TV (mostly sports) thrown in about 70:30. I have decided to go with 2.35:1screen, but do I need a curved screen? From what I read, it will alleviate pin cushion if throw is too short. I used the calculator on Projector Central and it said I need a throw of 16.7 for the screen size of 120. I have a room of 20 x 12, so I think I should be fine with a flat screen. Please let me know of you opinion. Sorry for the long winded post!

You would only need a curved screen if you plan on buying an anamorphic lens, but I assume you plan on using the zoom method with the Panasonic.

Thanks!
Yes, from what I read about the AE8000, the lens will switch between 2.35:1 and 16:9 with no need for additional lens.

Welcome to the obsession beekay. Short answer is you should be fine with a flat screen. Long answer is, we need more info to really be able to give you good advice. What are your plans for soundproofing the room (if any)? Is 20x12 the finished or rough dimensions? If you're going to do clips/channel double drywall, then your room will be closer to 11.5' wide. At that width, a 120" screen MAY be too wide. The best advice I was given, was to design the room first, and pick the equipment later. Looking forward to finding out more about your build!

Hopefully there's a picture above! This is the plan I drew for the contractor. The finished room dimension will be 20 x 12 and I am considering only the rectangular portion of it...

Other than an anamorphic lens, a curved screen is helpful with wide screens (wider than the seating rows) and when the edge of the image area happens to be close to the side walls. As the image gets closer to the edge of the screen from the center line, more and more of the reflected light from the screen is reflected into the side walls. This can provide a picture which is dimmer as it approaches the edge of the screen and a reduction of in-room ANSI contrast as a result of light splash on to the side walls.

Zoom method works, but what about films that change aspect ratio within the film itself which seems to be becoming more popular? Films like Batman and Transformers just to name a couple off the top of my head. This obviously will cause you to keep that remote in hand at all times...unless you like watching a portion of your film on the floor and ceiling. This is called exit door effect.

My Transformers Bluray does not change ratios, you must have a different version (IMAX?) or maybe it did and with my super black border I didn't notice.

Finally done! Elite screens screwed me over shipping the Lunette screen in - apparently they don't make with AT any more. But without letting me know they ship their Peregrine sceen - after framing my screen wall I had to do some last minute construction and design changes. With me design myself, this was just painful. But in the end the home theater looks great and picture and sound awesome.

Some more pictures...I have the speakers hidden behind the false wall framing. I was worried about quality of the picture on an AT screen, but with a bright projector like AE8000, it does look nice and clean!
