Summary: I have owned and used numerous projectors for years now and this little gem compares with the best of them. At work I use a 3000 lumens projector that weighs 20+ lbs and has a great picture with lots of features but it cost $8K and picture wise it has nothing on the Optima EZPRO 739 DLP projector.
Summary: Personal Experience Iâ€™ve had my 739 since Jan 07. Out of the box the colors need to be adjusted. I used some of the suggestions that other users posted and it made a dramatic improvement. Adding a lot more blue seemed the main color I remember adjusting.
Summary: Personal Experience Came to this from the X-1 like a lot of people. Looks great with HD sources DVI and Component not very good with everything else. Seems to be getting louder over time. Great 4:3 in a contrelled lighting environment.
Summary: Personal Experience I have had the 739 since march of 05. I have been absolutely thrilled with it until recently. I switched from direct tv to cable. Whenever I try to use the DVI connection in conjunction with cable box I get a DVI error like Drew mentioned.
Summary: Personal Experience Coming from an Infocus X1, I am happy with the 739. I've had it for approx 3 weeks now. The svideo and composite inputs don't look as good as the X1, but using the component to VGA adapter, the 480i looks as good.
Summary: Personal Experience purchased 1 week ago, vga adapter 1 day ago - Excellent all-round pj, I agree with 99% opinions here. Problems faint but often noticed - vertical bars scrolling up image (more noticeable in lighter scenes), regardless of in-source or pj mode.
Summary: Personal Experience I just had a theater room constructed in my home with studio seating, raised second row, mini stage, 133" screen, etc. I am using the 739 projector and can not get over the value (features/performance/cost)!
Summary: Personal Experience This projector is amazing - have it set up as a screening room in my NYC apartment. It's truly phenomenal. I only have one complaint - the projector only has  DVI input.
Summary: Personal Experience Six months ago, I bought the Optoma 739 for classroom presentations at our church since it has a DVI input that matched the output of my Mac 12" Powerbook. Works great on this. Then I noticed that the unit would interface nicely with the Hi Def.
Summary: Personal Experience I think I saw less rainbows during the 2005 pride parade. The throw sucks if less then 15 feet away, however they do have a short throw lens for just shy of $1000 (not bad if your and idiot).
