After a lot of deliberation, I just placed an order for a BenQ W1070.  Was confident with my decision until I read this excerpt from a shootout review between the W1070 and W5000

 

"This extra light output is most useful when watching 3D movies, where the W1500 will be able to support larger screen sizes than the W1070. The W1500 should be capable of lighting a 100" diagonal screen in 3D, while we would not push the W1070 past about 80" diagonal."

 

Is this accurate?  Does the 1070 really top out around 80" for 3D viewing? 

 

I was hoping to find a projector that could  fill a 120" screen in 3D at about 13 Feet. 

 

Is this possible with a $1500 budget?  I would prefer DLP and something that can handle a living room environment with a little ambient lighting.

I have a w1070 on a 126" screen @ 11'1" throw and 3d is dim IMO.  It helps to use smarteco and turn up brightness to 55, but it's still nothing like it is in 2d.  I have a BOC screen so if you had a high gain screen you might be able to pull it off.  But having your projector at 13' isn't going to help the 3d brightness.  

 

I would say 80" is pretty conservative, I think the W1070 would power a 100" 1.0 gain screen in 3d all right if you shortened the throw to 10' or so.  

 

To go 120" you could go with the Optima Hd25e.  It's brighter than the W1070 and W1500 and is under $1000.  The disadvantage is that it's really meant for longer throws than 13'.  120" will be max screen size at 13' from the screen to the lens.

I have a 120" 16:9 white screen using a Mitsubishi HC7900DW that's 166" from the screen (144" is the minimum distance for projecting a 120" image). My room is totally black which probably saves me and my image. I have done 3D and thought it looked marvelous. In fact, I was shocked at how good it looked. I'm not familiar with your projector, but the 7900 is known to be low on the lumens and considered a questionable projector for 3D on a 120" or bigger screen. The HC7900 is a steal right now. It performs like a $2000 projector but can be found for $900 and less on the internet.

If I went with the Optoma, wouldn't the HD25-LV be the one to look at?  Considering I will be dealing with some ambient light and want a 120" 3D image?

I would love to get the HC7900 and definitely thought about it.  My HC4000 has been great to me. 

 

But I will be in a living room with a little ambient light to deal with.  That is my worry about the Mitsubishi.

I did think about suggesting that.  But since I have no real experience with either one, I don't know how bright is too bright for a 120" screen.  I suppose going too bright is probably better than too dim, you can always run in eco.

 

Edit: I see you already chose, that AE8000 looks like solid choice.
