Projector Screen Size for Large Venue?

Question

I am in charge of the slideshow presentation at my cousin's 18th birthday this coming weekend and the place where I rented the projector from has a projector screen with the size of 6'x6' (70 in.) To me, this is small since the venue is at a hall. The hall doesn't provide a screen but they said that we can use the white wall as a screen. Is this ok to do? Are there any alternatives that I can do? Use a white sheet or something? I am totally clueless right now.

Any advice will do..thanks in advance!

Answer 1

Hi. The white wall should be ok as long as it is not shiny.If it is too reflective you could try the white sheet as you suggested .See if you can attach it flat to the wall so there are no bumps sticking out (stretch it as much as you can. and secure it around the perimeter of the sheet to the wall.)

okay, the length of the video is somewhat immaterial. What matters here is the size of the screen, the ambient lighting conditions, the resolution of the source material... As a projectionist and a manufacturer's certified repair tech for several different brands including barco I love the picture quality of barco, but find them to be too pricey. The replacement bulbs for a barco flm hd12 (12000 lumens) which is what we use on a 16 to 20 foot wide screen are about 5,000 dollars and they last 1000 hours (though not really/they've never lasted as long as the manufacturer specs). And even 12000 lumens isn't very bright in high ambient light situations. By the way barco's 12k projectors with lens is going to cost around 40 grand.... A 3000 lumen projector in a very dark room will suffice if the screen size is around 12 feet wide... Sanyo makes cheaper easier to set up projectors (which are actually sold under a lot of brand name, including christie, eiki, infocus). Their 12 k projector is about 16 grand without lens and uses four 400 dollar bulbs so that if one fails the projector still works (average bulb life also 1000 hours). Your best bet is to look at ebay for a used projector (I'll sell you a used barco 3000 lumen projector for $300 plus shipping). Rentals vary wildly, a 3000 lumen projector not delivered, without tech goes for $125 a day from my shop. 6000 lumens $400, 12k lumens $550, 15k $700.... by the way Ben, k means 1000 and usually refers to the light output in lumens. espescially since hidef is now usually 1920 x1080p (not 4k).. 1920 being the total horizontal pixel count and 1080 progressive being the vertical (lines) resolution.

If you think it is small, use the wall.
Just go there and try in out on the wall! Or at any wall in your house.
Do you really think anyone will care about color accuracy at your cousin's 18th b-day?

You can try the above mentioned things, or, you can try some local AV rental houses to rent a larger screen. You would have to set it up yourself though.
