My AE4000 came yesterday and I set it up to project on the wall. I was planning on going with a 140" 2.35 screen but after seeing the projector zoomed out to 150" on 16:9 I was pretty amazed! Both screen sizes are the same width MOL its just the height difference. Going with the 16:9 I still get the same 2.35 image size so is it a no brainer?
The screen I am looking at is a 1.2 gain. I'll me mounting the projector at around 15 feet and using the max zoom. The I checked the calculator on projector central and it shows 14fl? What is the number I should be shooting for?
14-16 but as the lamp get 300-500 hours on it, it can loose as much as 25% of it's brightness or more. Not to mention if you calibrate the projector you will not hit that light output with a new lamp. The calculator uses manufacture light output specs which are normally inflated.. Just something to keep in mind with going really big with a low or mid-range HT projector.
If the Panny is as bright as my older Epson's (8500Ub, 8350) no worries on a screen that big. I run a 153" and it looks great. You may have to change the bulb a bit sooner than a person running a 100" screen but, for me anyhow, worth the cost for that cinematic experience! Bulb quality control more of a factor than screen size. I had bulbs go at 800 hours and others go at 2000.
If I were to do it again, I would go 2.35:1 though.
