@Cla55clown, as @b curry
said if the image is too bright other lamp modes can be used.
Your setup would greatly benefit from an ALR screen for lights on viewing.
I have an Cinegrey 3D (1.2 gain) which claims to reflect up to 65% of ambient light.
The parts of the projected image that are bright will be reflected back with increased brightness. If ambient light is present that may wash out the dark parts of the projected image, depending on strength and position.
What this means in practice is if mostly bright pictures are projected, like a cartoon with bright colors, a studio environment with lots of lightning (like the news), or most athletic type broadcasts, it can be viewed with lots of lights on. The only requirement is that the lights are not directed towards the screen from the same position as the projector.
I played brightly lit games at noon with the windows open, no clouds on a lamp that probably was giving out 1000-1200 efective lumens, and got a very good image. All the light was coming from one side, from 160 and 45 degrees. White walls.
Don't have pictures of that, but I do have some (with sports) with a single light about 1m/3ft from the screen: https://www.avsforum.com/forum/68-di...l#post57673262
I had a Black Widow Grey Pearl (paint) 1.2 gain (with metalic parts) large sample which matched the Cinegrey 3D in the dark. But with lights on the image was very washed out, including the bright parts.
There are ALR paints that can do a good job with lights on, but it's more complicated: https://www.avsforum.com/forum/110-diy-screen-section/
I also had a grey matte 1.0 gain screen which gave better blacks at the expense of everything else. Colors washed out, white was yellow, and that was with the lights off. Lights on was worse.
I imagine a room with a bar and pool would have some, and depending on the number and the intensity the entire image could be washed out with lights on, whereas with ALR the bright parts would be retained and enhanced. No matter what projector you have (unless a very high lumens model) the image will be washed out with non ALR screen. So a negative gain grey or white screen would not be recommended (IMHO).
If you can build a wooden frame the fabrics themselves can be acquired at a fraction of the cost of the screen framed by the company.
Carl's ALR, Cinegrey 3D and 5D can be had for under $200. The fabric is an 135 inch, 16:9 format.
The framed versions of the Cinegrey's cost between $800-1500 depending on the diagonal. Carl's does not frame the fabric.
Other alternatives are:
Des Pulsar 1.4. Fabric is just under 1k (I think), framed is around 1.5k.
As someone recommended above, XY Screen. Haven't had any experience with these ones.
There are other alternatives, but more expensive.
Some video examples of what you can expect. You can notice the dark parts seem to get washed out, while the bright ones much less.
