What a poor piece of equipment and a terrible company with horrible customer service. Over $300 to replace the lamp. This Optoma ep727's lamp burned out in under 200 hours. The company won't replace this. YOU SHOULD NOT BUT THIS PIECE OF JUNK.
That happened twice; once during rehersal and once during a performance. The set largely consisted of slides projected onto a backdrop, and we were worried about having the slides bright and sharp, despite the long throw and the bright stage lights illuminating the actors. The projector had no trouble with long 'on' times. No trouble - this was great. As it was, it only took a minute or so to get fully operational again.
I was really impressed when it recovered without a hiccup when we triggered a circuit breaker and the power went out. It worked flawlessly. It was on continuously for about 5 hours during the dress rehersal, and for about 2 hours for each performance. If it weren't for that, I'm sure the audience would not have noticed when the circuit blew during the performance (it was during a transition in the play, and a blackout might have been appropriate). In fact, the only complaint I have at all is that the projector boots while projecting the name "Optoma", then hunts for the computer signal.
The keystoning feature was very useful, since we were projecting from well above the stage. The Optoma EP727 projector was much smaller than we expected, and very lightweight, but it didn't feel flimsy at all, just solid and well-built.We bought this to use for a theatre show. We were not certain the remote would work from that distance (the projector was 20' in the air) but we had no problem turning the machine on and off remotely. We did not use the DVI input for this show, but I tried it with my home computer (which has a DVI video out) and the projector image looked especially sharp. We fastened the projector up on the lighting bar, and strung a 50' VGA cable up, over, and down to the controlling computer (an old G3 Apple iBook).
Basically, I love it.
I use it for slide shows and video projections, as well as showing HDTV. The projector has all of the inputs I need as well as the feature controls desirable for my range of uses.The only negative I have found is that the control buttons are very tender indeed. I have accidentally powered the projector down numerous times while adjusting the direction or tilt. I find my Optoma EP727 to be just what I needed and at a nice price. Its size and weight make it very portable and the bulb brightness is suitable for use at a wide range of venues. A detent position on the buttons would be a good improvement.
I hooked it up on my laptop and had great picture. Great quality projector. The reason I gave it a 4 star is because it doesn't have a RCA inputs.
