Hi, I have a Vava UST projector, and want the best-possible image at full 150" in a room that gets some ambient light. I am willing to pay a professional to prepare and paint the wall. I assume the wall needs to be perfectly flat (as in: use a laser to really be sure), otherwise UST will be out of focus in some areas.

Where do I find an expert who can advise me on specific paint choices (grey vs white, gain, etc), and who can prepare my wall to make it perfectly flat? Am I looking for someone who does skim coat, or is there another word for this special skill? The AV store in my area knows nothing about projectors, claiming they are not selling well enough.

Thanks!

The ONLY reason to use a wall instead of a screen is to do it yourself and save some money.

Otherwise, buy a screen.

Silver Ticket has 150" screens for just a few hundred dollars, and you can bet that is the same price you would pay someone to come out and work on your wall.

You can even paint the screen material if you would like to.

The FAQs has some information on DiY options that you may wish to consider.

Thank you for the advice. I'd like to add a couple thoughts about my rationale, which led me to think that I need the wall paint approach:

1. I'm not using this to watch movies. My goal is to build a 'VR cave' type of experience, where the wall just sort of disappears. I want to project all the way up to the ceiling and left/right walls.

2. Given that I want the screen to disappear, I want to avoid any sort of border. Can a screen appear borderless?

3. Because it's UST, any slight variation in flatness is magnified. Will a screen be so flat that the UST will remain in focus, and any air currents not show ripples?

Thanks again!

Screens, obviously, have a border. So, there's that.

But, large screens are tensioned in all directions and come with hardware for wall mounting which pulls on the screen as well to keep it from flexing.

Adding the details makes a reasonable argument for ditching a screen. You would want to speak to home remodelers who do drywall work and it is something like a type 5 drywall finish or some silly name like that (I can't remember, but I saw it on HGTV!). This is what they use in million dollar homes and the drywall guys that can do it are excellent.

But, general contractors can get you the right people for this type of work.

Yes, a screen would be cheaper, but it will show a border and won't disappear in the room.

A concern will definitely be whether or not the VAYA projector can even go that large without focus issues. Often with UST lenses they are size limited from about 80-120 inches diagonal as a function of the lens itself. So, check on any lens limitations with the projector in use.

I wish we would hurry up and see these UST projectors from more major projector manufacturers.
