ok that sounds good, I'm looking at getting an Epson Pro 6030UB which is rated at 2400 lumens, but I'm not sure if that's an accurate measurement or not. I'll have to find a good fL calculator and play around with my theater design to see if its going to work.
If a projector is too bright, is there usually an adjustment to lower the bulb brightness?
Are you going to calibrate the projector?

Re: Seymour CenterStage UF

Yes, I plan on calibrating it. I just didn't know if the brightness adjustment adjusts the bulb brightness.

Re: Seymour CenterStage UF

The Epson is rated at 2400 lumens, as you say. However, keep in mind that is max output, with no regard for proper calibration and accurate color.

Over at projectorreviews.com, you can read the review of the 5030UB which, as you may know, is identical in performance to the 6030. They used the Cinema mode and calibrated the projector, and ended up with 644 lumens in high lamp mode, with the projector at mid-zoom. Subtract 30% for telephoto (projector as far back as it can be), and add 28% for full zoom in (as close to the screen as it can be). Subtract 25% - 30% for eco lamp mode.

They also did a "compromise" calibration of the Dynamic mode. This mode is very strong in greens. The goal was to make the picture watchable while maintaining as much brightness as possible. So they calibrated enough green out of it to make the picture a lot better without taking away too much brightness. The intent was to use this mode with some ambient light, for sports viewing and such. The result was 1487 lumens (again, projector at mid-zoom and in high lamp mode).

Just something to consider. The real gain on the CenterStage UF is well below 1.0 (I think around 0.8 IIRC). The CenterStage XD is right around 1.0. So, assuming a 100" 16:9 screen, with 644 lumens from the projector, you're looking at about 21 ftL from the XD screen and about 17 ftL with the UF screen. That's usually considered plenty bright for a light-controlled room.

How big are you looking to go?

Re: Seymour CenterStage UF

bkeeler10 said it all!!

More or less, consider ~650 lumens in play after the calibration.

Re: Seymour CenterStage UF

You should get samples of both. The XD is definitely not 4k. I can see the texture at around 8 feet or so. I can't see any texture with the Enlightor 4k material. I haven't seen the UF yet.

I have been in a couple of theaters with XD and the texture isn't that noticeable while watching. I think one gets used to it. The difference would probably be noticeable if you put the samples on the wall.

Re: Seymour CenterStage UF

I have a 5040ub and obtained both the XD & UF samples from Jon @ Seymour. The UF is a more flexible/stretchable material which might be good for a fixed frame but my screen is a motorized one so the only option for me was the XD which has a higher gain than the UF. Falcon also makes a good DIY fabric at a slightly lower price than the XD. I think the Falcon was a bit tighter weave than the XD but more open than the UF so you may want to get a sample of each like I did.

In the end I decided to buy a finished screen rather than DIY this time as I found a deal on a 120" Elite Screen that I will be installing next week
