rs2 brightness

It should be fine....

Assuming that is a 120" diag. 16:9, you would see about 14 footlamberts with a new lamp at best mode. However, figuring light loss from a dimming lamp and not the "best" mode setup, you probably would be more in the 8 footlambert area. I might suggest you consider a screen with some gain if you need one that large.

Get a Da-Lite HP screen and it will look great! I have my Pioneer FPJ1(re-badged RS2) throwing on a 106" screen with around 4-500 hours on the bulb with an 11ft throw and it looks fantastic. Also, I set my projector about 3 ft above eye level. While that may not be the best use of the HP I actually prefer it because it gives me the added brightness w/o raising black levels much. If I had the room to do a 120" screen I would have gone that route as well.

Note that 106" and 120" have a 30% increase in surface area...big difference. That being said, I agree the key thing is the higher gain than unity.

Very true.

would a +1 gain work?

Gain +1 or unity gain are the same. If you want more gain then 1.xx/2.xx is what you need.

I had the RS2 with a 120x51 'scope' and anamorphic lens and for hdtv 1.78 I masked it down to 91x51 on a Carada BW, which I think they claim 1.3 gain but I've read a couple reviews saying it was closer to 1.1. Nonetheless, in a bat cave type room I never noted it not being bright enough.

i have a 120 wide 2.35 with a rs1 and rs20 and they were and are bright enough to light my screen without any problems

Again, remember a 106" and 120" have a substantially different amount of surface area...14" diagonal sounds like a smaller change than it really is.

My RS1 with a new bulb isn't quite bright enough for 120" at 1 gain. As far as I know the RS1 is brighter than the RS2?

I've got the 120" HP screen in a bat cave, with the RS2 on low power because high is to bright. I love this combination.

Hi Power is a great option for those who 1. can use it the way it is intended and 2. for those who have larger screens with lower output projectors. It is a great fabric.

For a projector that has lower light output than you want, the Da Lite HP screen is an available cure.


But unless you plan to use high gain screens, personally I'd be careful about expectations of the RS2 with a larger screen (beyond 105" diagonal). I'd seen it several times on various screens, the biggest being 105" diagonal, unity gain, and it always struck me as a bit dimmer than I'd like.

I have an fpj1 projecting onto a 96 inch carada classic white screen. Whites just seem to "glow" instead of looking like proper lights. Im about to sell the thing for a dlp with more lumens. Is this a fault with my screen? Projector is only 13 feet away.

Not the screen...the Carada is a very flat uniform fabric. Though I wonder on your settings if you are overdriving the projector possibly...
