I highly doubt anyone on this forum has a setup that's too bright. I have a 3M 9850. It puts out 11K lumens on it's normal setting. There is a switch to set it to 7k lumens. I can assure you that the 11k mode is vastly superior.
Let's look at it the other side of this. When your light source is not very bright, you can achive very dark, black looking blacks.
You also get black looking dark greens, black looking dark reds, and black looking dark blues.
Watch a movie that takes place at nightime. The characters clothes are all black. No buttons, seams, or wrinkles visible whatsoever. The shadowed portion of their faces is pitch black.
Your not going to get CRT like blacks with an LCD projector and attain a watchable picture. Lowering the brightness will only black out your picture. If you have an LCD, you need to deal with the greyish tint to blacks- or else have a practically unwatchable picture.

Lifter, I would really like to see some comparison pictures of what you're talking about. It would help many of us figure out what you're saying.

What you say is true. but good commercial LCD projectors will put ~2000 - ~3000 ansi into a screen through a 400:1 or 500:1 lcd.
All LCD's are vaguely the same light efficiency. "They" use light recyclers to catch the 50% unpolarized light and reuse it. We use more light.
Yes, grays go more towards gray. But its not a problem till the 4000 lumen arena. I'll tell you how bad a problem it is if i ever get this blasted reflector built. :-]

on my regular system - still using the 600 watt 17000 lumen incandescent - i have to continually play with the gamma to give me any details in dark scenes without totally washing out light scenes. every scene is a new battle, its actually quite sad really.
even with some seriously high powered 400 watt MH systems, we still get considerable fadeout in dark scenes. probably catching about 15,000 lumens of light coming off the bulb.
we need a lot more light before it becomes a problem. thought i'd provide some examples.

you know, something to try and play with is the ffdshow program
used for divx playback (And DVD).
besides the usual gamma, contrast, and brightness settings,
there is this lumina and chroma settings.. don't know what
they heck they are.. but tweaking them really does a nice
job of brightening the scene without graying the blacks too
much..
I'm comparing this to just using the ol' brightness and
contrast settings found in windows media player.
really has brought the quality of my picture to higher
standards
