Summary: Personal Experience I've owned this projector for a few weeks shy of 3 years. For me, it's a daily use projector as video for my home theater system. I don't have the A/V experience that some others might have on this site but I can say I'm very satisfied with this projector. The brightness is good using the economy mode and I have 1976 hours on the bulb which I'm going to continue to run until it quits.
Summary: Personal Experience This Compact little unit is brighter and has a sharper picture than anything I have seen in its class. As A Professional A/V Tech in the Las Vegas Trade Show Industry I deal with all of the Name Brands. The EP728 has the most Vivid Color Reproduction of any of the Portables out there even to this Date. An Excellent projector choice for small home thatre setups.
Summary: For those of you considering a DLP project this is a very nice one. Replacement lamps are available at a much lower cost that most DLP projector. And despite what people will tell you this is HD at 1027x768, HD is 720, and there are no television shows broadcast in 1080p.
Summary: We got this for our office for the occasional presentation or meeting where we need a projector. As other reviewers have said, the button layout is completely insane. It looks pretty, but while leaning over a table in a semi dark room to toggle something you'll hit the wrong button. Very frustrating. With all our laptop screens being widescreen, I regret not getting the otherwise similar widescreen version of the projector, but I can't fault the projector for that!
Summary: I own a sports bar and purchased 7 of these projectors. 4 out of the 7 have all had the exact same problem where white dots slowly begin showing up on the screen until eventually the entire picture is just solid white. Unfortunately for us 3 out of 4 were purchased slightly used and were out of warranty. Forget about repair. Optoma's service center charges $700 to repair the unit which is more than purchasing a new one.
Summary: I've been giving presentations for over 20years now and I can honestly tell you that this product hits the sweetspot with regard to price and value. 2700 lumens is bright enough for most any occasion whether it be in a small office or large hotel conference room. I've been an independent consultant for the last four years and typically give 15-20 presentations per month.
Summary: I just tried out this EP728 in a multi-purpose hall which holds about 120 persons and has lots of windows. I closed a few of the blinds but left plenty of ambient light in the room to see how bright the movie would be. The picture was great on default settings both in sharpness and brilliance. I was very pleased with the ease of plugging this unit into a DVD home theater system using a S-video connection.
Summary: The Optoma EP728 is an exceptional projector for the budget minded and will meet the need of most business and home applications. While this projector will not provide true 1080 HD (due to scaling to it's native resolution) the picture quality is excellent and provides a bright, beautiful image in 720 HD. The difference would be slightly visible closer on a smaller surface, but it's nearly imperceptible at a distance on larger screens.
Optoma EP728I. Buena ocasión de tener un proyector
16 November 2009
Summary: Buenas noches. Ahora voy a escribir sobre el ultimo aparato que me he comprado, un proyector para ver las pelis a lo grande en una pantalla. Con un presupuesto austero como es normal en estos tiempos de crisis estaba esperando la ocasión propicia de encontrar uno barato, y parece que he tenido suerte y paciencia, este Optoma del año pasado ahora lo puedes comprar por tan solo 300 euros online.
