    Hi, I'm thinking about buying a TV Projector and am just wondering, in terms of image quality, if there is a major difference between a projector screen, and a wall painted a nice bright white.

    Hope this is not a daft question :b

    Oh, and while we're here, would someone be kind enough to give me the pros and cons of TV projectors.

    Thanks.

    a screen will change the brightness characteristics with not only color but shape of the fibers (or whatever you want to call them I can't remember the technical term)

    So will it make a big difference or could I get away with the white wall?

    The darkest blacks will be the color of your wall in the amount of light in the room. If you have an LCD PJ, grey screens give better black levels, you could paint your wall light grey etc.

    So, does it make a huge difference or not much?

    And if paint is ok, what is the best kind to use?

    Thanks x

    Basically, a very flat surface painted with a pure white will be fine for non-supercritical applications. I am assuming you're not buying a super high-end projector, so flat white painted surfaces can work well for a cheap DIY solution. the important part is to have a very flat, untextured surface. Most walls have some kind of texture, so it's better to use some kind of material over that for a perfectly flat surface.

    For more high-end theater setups, a proper screen is desired, and things like gray screens, high gain screens, etc can add to the complication and cost, but can also provide stunning results. These screens can be from the hundreds of dollars, to many thousands, so obviously cost is a significant factor.

    I've had fine results with 30 bucks worth of blackout fabric stretched over a frame, it looks great. But if I put myself into super-picky mode, a proper screen with a slightly higher gain would look slightly better, and be easier on my CRT projector. But for entry projectors, cheap DIY screens can give superb results for very little cost.
