Resolume Forum

I need to shoot at 210cm X 150 white wall in little bright enviroment(art museum) with movie footage.
... which is better?? plz help 1024 x768 resolution is ok??
Sony's resolution is 1920x1080 and LCD , Optoma resolution 1024x768 and DLP.

I would get the Sony for sure! It may be a little less bright but you won't really be able to tell the difference. The three main reasons to get that one instead of the Optoma are: it is HD AND has H & V lens shift AND HDBAseT!

HD will be much better in a museum environment since people will probably be closer to your work.

With the lens shift so you'll be able to precisely adjust your image to your screen.

With HDBaseT you'll send a signal over a CAT5e/6a cable if you've got an HDBaseT transmitter which I highly recommend in a museum environment since you'll probably want to do a clean installation and your computer is more than likely to be far from the projector. HDBaseT will let you transmit 4K over CAT6a at 300ft with no degradation or latency.

Thank you for answer!! 2000:1 contrast range is ok?
I am afraid real black :p when I shoot in dark enviroment.

I personally think that anything about 2:000:1 is somewhat of a marketing/sales gimmick.

Take a look at page 2-4 of this article

and if you don't have time just take a look at this diagram:
