Thank you for you reply.My specs are close... I use a Falcon Screens Platinum (1.3 gain) scope screen that is 130" wide. My room is light controlled. I run the projector at medium power for 16:9 material and for 2.35:1 I run high power about 80% of the time.
I'm very happy with this setup.
The 2.35 screen I'm looking at is 133" diagonal, which is approx. 122" wide. If yours is 130" wide and also 16:9, then your screen sounds significantly larger than the 2.35 Neve I'm considering. Your gain is slighter higher than the Neve which would give your screen a slight advantage. I would prefer to use ECO mode for most viewing, and hopefully only need to open the IRIS to reach the lumens I desire (13 - 17 FtL). I'm hoping not to have to use Normal mode as my base setting. I would however say, for my viewing, that I do like Normal mode ever so slightly better than ECO mode, but due to the near noiseless fan I prefer ECO. Plus in ECO mode I can run my PJ for 20 years before reaching half lumen output.
