Can a grey screen ever make sense in 100% light controlled room?

I have a w1070 and the thing is just too bright. Black levels aren't ideal.

Is a gray screen a viable choice for me or am I better off to pursue a matte screen and an nd filter?

I'll also be darkening the walls to help, but wanted to ask if it is worth investigating gray for the screen when you have light control.

Thanks

/edit: also the pj is brand new with only 8 hours on it so I don't want to overcompensate when the bulb will naturally dim.

Screen will be about 100" if it matters

How big is your screen, and what is " too bright " ? Do you have a light meter ? I'm just curious how many foot lamberts you are getting now.

My current screen is 120" and I don't have a light meter to make measurements.

However, I also haven't painted the room dark yet and it's a brand new projector so I don't know what it will settle into when the room is darkened and the bulb not so new. That's why I haven't jumped on replacing the screen quite yet. I plan to move down to somewhere between a 100 and 110" screen. My room is just not wide enough for the 120".

You might darken the room first, and of course it will not be as bright as it is now for long - the reality of lamp dimming. What screen material are you using?

Currently an Elite Screens 120" which is the worst screen I've ever bought. The waves/curls are crazy and the case came dented so it won't roll up and down smoothly without leaving black marks on the screen. Can't wait to ditch it but I want to ditch it for the right thing.

Why is there even any question here?

With your w1070 at mid-throw you'd get up to / over 30 fls

On Low Lamp your still over 18 fl.

The w1070 absolutely needs some black boosting assistance, but you do not want to sacrifice your Whites.

You mention a totally light controlled room, but you also bought a retractable screen...so that seems to indicate it's not a dedicated Theater.

White or Gray, with a non-tensioned retractable screen you will always have the prospect of waves, edge curling, and / or wrinkles.

Here is a link to a Matte Gray Tab Tensioned Electric Screen. It's 119" though. But damnable affordable. $499.00
http://www.amazon.com/Tensioned-Proj...ojector+screen

.....and a Matte Gray 100"er. You'll have to call for pricing.
http://www.snapav.com/p-370-dfm-tab-100-hc.aspx

Both screens would have a Gain of 0.8 so respectively size-wise from big to small, their Foot Lambert ratings using the w1070 throwing from 11'- 3" (mid throw) would be 17 fl and 24 fls

If you do paint your surrounding surfaces a Flat, non reflective color that has no Yellow or Red in it (...avoid Tan or light Brown as well...and it certainly does NOT need to be a ugly shade of Flat Black... ) then you'll have accomplished every one of you needed goals.
(...in deference to Red, if you want Red, then it must be a ultra dark, flat Red...for the walls only. Dark Gray for the ceiling...)

I suggest a neutral Light Gray...or a medium dark Blue Gray for the walls, and a 2-3x darker shade of the same color for the Ceiling.

That's my take. Now let's see what shakes out.

Can you be more specific? Inquiring minds need to know !

I'm moving forward with a 110" fixed frame screen 99% sure from Carada. Since their grey is REALLY grey, I will probably go with matte white 1.0 and continue to experiment with an ND filter to darken the light output. MOST of my viewing is 3D so that helps too. If I instead go with Stewart CIMA, I may choose Tiburon since it is higher gain than the Carada grey.

For the room, I am going to paint it much darker and flat, probably the ceiling and screen wall "Stealth Jet" by Behr, and a slightly lighter (but still dark) bluish grey for the other walls.

Any update on this? I just ordered a Seymour AV Glacier White 1.3 gain screen. My room is totally light controllable, and painted dark browns, but there could be occasions where I might have some of the lights on, so I struggled a lot with my screen material decision. My PJ is going to be the EPSON 6030ub, which is pretty bright. I'm hoping to run it in eco mode most of the time, and maybe only use bright mode for 3D. Just curious how your situation is panning out.

I did go with the 118" Carada 1.0 screen. It is excellent, and I like it.

I really can't say if a gray screen would have been 'better' as the w1070 is still new and very bright; too bright almost on 2D material, but that is dimming over time. On 3D material which is the bulk of my viewing, it is perfect. Sometimes I'll use a neutral density filter on 2D material but as the bulb starts to dim I bother with that less and less.

I'm very happy with the choice I made, and the Carada is a nice product! I have owned a Stewart in the past though and the Stewart was better engineered and pulled together 'tighter'.

I also did go ahead and paint the room 'Stealth Jet' by Behr. It is a greenish/gray color and very dark. I will try to post some pictures later this week.

I know no one probably cares, but I did promise to post pictures and realized I forgot. Here is a picture of the finished theater.

I am sure this made a big improvement. A 100% sealed room with no window is not a light controlled room, if the walls and ceiling are white or some other light color. A light controlled room, controls the light from the biggest source of light in the room and that is the light coming off of the screen. Now that you have started darkening your room, you are starting to have some light control and with it, a greatly improved image.
