I am trying to decide between the bd 1.4 and dnp 23-23. The .8 versions of both products are out because I do not believe they will be bright enough.

Here is my delima. I am wanting to go with a 110 inch screen. With that size my throw ratio will be 1.625. The bd claims you need 1.2 and the dnp states a minimum throw of 1.8. My fear of the dnp is hot spotting and bad sparkling. Do I really need to meet the 1.8 ratio?if not will this screen perform better than the bd 1.4 even with a 1.625 throw ratio?

I have samples of the bd 1.4 and its impressive but I do notice a pretty large drop off when putting the samples to the far sides. The dnp is also way brighter. In fact if the gain really is 2+ it maybe too bright even in Eco mode (over 27fl)

Anyone care to throw an opinion out there?

1.6 vs 1.8 ratio, does the 1.6 mean you have to have the projector further back than the 1.8, or closer ?

Closer

The Black Diamond has a much more dramatic drop-off in brightness as you move off-angle and it color shifts as well. On the other hand, the BD will do a better job of reflecting ambient light coming from the side of the screen. I have a 100" diagonal 08-85 DNP and it is plenty bright for me. I have a SIM2 C3X-E mounted at around 13.5 feet. It is spec'd at 2500 lumens, but I don't know what it's really putting out. It has been calibrated, which usually results in a lower output.
