I am painting my wall right now with a couple coats of primer and then if that looks thick and smooth enough I am going to add on Behr Silver Screen paint (770E-2). It gets good reviews for a screen surface so I should like it. We will see.
This is a link to the
new projector setup photo set where I will be adding pictures of my painting and the progress as it gets finished and as the projector goes up and I will add another post that is more complete when I get to a more final stage in the process. The stages are
1 choose a target size and prepare an area larger, I went with 3 inches on each side extra so I would have some room,
2 sand and primer the surface to smooth it out and get rid of the yellow,
3 paint plenty of grey on the area,
4 mount the projector and figure out the best size for the room and the projector, the larger the image the dimmer it will be but the blacker the blacks so a balance must be reached and
5 paint a black border around my final screen size to enhance contrast and improve the cinematic feel.

You can see this image
big to check out the surface detail. There are some little marks but it is very smooth overall. This picture below was taken when there were still a couple coats left for the wall.
Stage 4 So it took an extra day because Optoma changed the size of the screw holes. Lowes and Home Depot didn't have the screws I needed. Lowes had the area for the screws but the what I ended up with at home for sure weren't the right fit. Ace Hardware really came through. That place is nice. So after one awesome night of using the projector on the coffee table projecting an image about the size of my last setup, 92". Because the projector was brighter than I imagined and because of the changes of the screen surface I think I could go really big. I might go ahead and fill up my whole painted space or I might go with my original estimate of around 110" being the correct size. This image below is 107", or pretty close to that. If it gets bigger my couch starts to be in the way and I already had to take the globe, chains and light bulb out of my ceiling fan. It hangs down just a little too low but any light fixture should work, probably just no fans.
If you click on this image it will link to the larger size.

And this is an example of why I was hesitant to paint my walls. I don't think that some spackle or mud or whatever would be able to get it totally smooth. I sanded it to get the intense peaks out but this is some serious plaster warpage. My experience with the previous screen assures me that these won't really be noticeable unless the bathroom door is left open which happens sometimes.
Update: You can't see any of this stuff. It looks great.
