Hi Everyone, I really am excited about this new foray into the projection world.

So, I bought my first projector, the Optoma Cinemax P1 mostly because I really like the ease of use, and the idea of using the UST projector as my everyday TV, as well as movie night, etc... I do NOT game, so that was not an issue.

The room I have it in definitely is not one I can black out, but most of my "serious" tv watching is in the evening, anyway. I will want to be able to watch some weekend daytime sports, so that is a consideration.

The wall which I chose is approximately 7ft,5inch high, and 13ft wide, all white, with somewhat textured white drywall. I set up the Optoma on my old TV stand, which is about 20" high. I had to pull the projector a decent distance from the wall, and I now have a 100" screen, with the top border about 3 inches from the top of the wall.

I am already amazed at how good the picture is, especially at night. Compared to my 10 year old 1080p 65" flat screen, WOW!

I have a couple questions.

I really like the idea of not having a screen, but am not sure I can do anything with the textured wall with screen paint, or whatever it is called. The other option, obviously, is to buy a screen. How much does the screen quality really matter? I was shocked to see how expensive they can be! Can I get a decent screen for under $1K? Any suggestions? I have read that the ambient light rejecting tech is what I should be going for....is this the case, or is it not really necessary and only would give minimal picture improvements?

Also, I think if I got a lower tv stand, I could get a full 120" size image. Any suggestions on stands to use that would place the projector at 8-10" off the ground and still look nice in the living room?

Any and all help and suggestions appreciated.

Thank you very much!!! Looking forward to learning all about this...
Jason

The big thing with UST (ultra short throw) ALR (ambient light rejecting) screens is that they are designed to take light which comes from a severe angle below them, and reflect that outwards towards viewers in the room.

A normal 'white' screen, just scatters the light coming at it towards everyone. It improves image quality and does a great job making whites pop, but it will allow light to be lost towards the ceiling, which may be undersirable.

Before going to a 120" screen size, I would get something you can set the projector on and test it all out to be sure you are happy with the final setup ahead of actually making a permanent move towards that size and setup.

If you do decide to get a normal white screen, then those from Silver Ticket are designed to work with UST projectors just fine. While they are not ALR screens, their smooth white finish does a good job at scattering light and working well as a projection screen surface.

It's a perfectly fine entry level screen at $250 for 120" diaognal:

From there you get into ALR screens designed for UST, and those are a fair bit more expensive.
