    Hi new to the world of projectors and need some advice. I looking at getting a short throw as I'm short on space. I'm looking at a used promethean prm-30 I was wondering if anyone had any experience with these projectors and general pros and cons of short throw. Can't seem to find a lot of info on these projectors so the more info the better thanks.

    Hi Tooter
    What is the intended use for the projector? My understanding is that Promethean equipment is mainly aimed at the business/education market, so it might not be best suited to home cinema or gaming if that is what you are looking for. I've not seen this one in action however looking at the specs online although it is 720p resolution it has a contrast ratio of 500.1 which is not so good for video. What kind of throw distance / image size are you looking for? Most home use projectors have quite short throw ratios anyway.

    I haven't owned short throw projector but:
    Pros:
    can be installed close to screen.

    Cons:
    no placement flexibility
    smaller selection
    higher price than long throw projector with same specs

    wrong about the specs-$$ ratio. truly. there are plenty of short throw for sub $800 with
    quality specs. Yes the ULTRA short throws are $1000+ plus but that's an entire dif application mostly.


    Here we go.
    Pros:
    100" image within 3ft of screen, better use of all available lumens,
    better for a non light controlled enviroment. Ambient light has less effect on screen.
    don't have to run HDMI to far, fan noise is not near viewing area,
    best option for people that rent apt/houses as they have will get atleast 100" screen no
    matter house large the apartment or house/ room.
    nobody EVER walks in front of it to cause a shadow or block the image.


    Cons:
    can't be place more than 6ft from screen so in rooms with vaulted or raised ceilings
    mounting can be a issue.
    Cant be set on shelf behind viewing area.
    very few with auto keystone correction.
    LED ones get pricey.
    Options limited for connections. MOST not all short throws have only 2 hmdi and maybe one vga.
    Most are DLP single chip so possible rainbow effect.( that most don't see)
