Does anyone have experiance using the Optoma EH501 for 3d home theatre? My theatre is very large with a 16' by 9' screen. Projector central recomends the Optoma HD25-LV for large screen 3D but it only has 3200 lumens compared to the eh 501 which has 5000. Are these about the same projector only a bit more expensive for more light output? Or would I be sacraficing video quality going with the EH501 and should I just mask part of my screen and go with the HD25-LV?

Is there another option under $2000 that would be best for very large screen 3D?

Any ideas or help would be appreaciated.

A 16x9 screen is about 144 square feet. For 3D I would shoot for 30+ lumens per square foot, so the HD25, while it is plenty bright enough for 2D at that size, will leave you wanting more for 3D.

The 501, I'm sure, is being built on a similar basis to the HD25 and HD131. It likely does take a hit in image quality for the added brightness with lower color brightness, and weaker black levels, but this is typical of these cheaper bright models. It will also take some calibration work to get the colors as accurate as possible.

All that said, I would think that this would be an excellent choice for the larger screen size on a reasonable price point.

Thanks a lot for the info. The older I get the harder it is to part with a couple of bucks. It helps to have a little confidence that I am not buying a door stop before turning lose 2k. Thanks for the back up!

I bought the Optoma EH501 and have been using it for a few weeks.

It did not install exactly as I had hoped. The lens shift option does not allow for straight on projection. It just corrects a little bit. Still better than nothing. I did have to scale down image size a bit due to projecter placement issues.

REVIEW:
2D on a 16' screen-- Looks great in a dark theatre. Had about 30 people over to watch Endors Game and it got a huge ovation in spite of being a lame movie.
I am just starting to have a critical eye but the EH501 looks great to me. Black levels, skin tones, and film like smoothness (not looking like masterpiece theatre) are some things I have tried to look for and I have been very satisfied.

3D on a 16' screen-- looks great with animated material (Wreck it Ralph, Dispicable me2, ect, ) and also great with stuff filmed for IMAX 3D like Great Reefs, and Hubble 3D.

I am not as happy with the live action 3D material I have watched so far (Man of Steel, Avatar, Star Trek:Edge of Darkness) There is a noticeable judder sometimes during action sequences and subtitles of stardates and places were so annoying it ruined the whole movie for me. Some of these problems could have been from my glasses. So far I have 18 pairs and about 4 different brands. Still trying to figure out which are best.

Overall I like it with the jury still out on live action 3d.

I just purchased an Optoma EH501 and would like to know if anyone has had this projector professionally calibrated for HD video or know of someplace online where I can find calibration specs. At first glance the projector looks great with Blu-Ray movies but I'm sure the image can be greatly improved if calibrated properly. I'm only interested in viewing 2D in a dark environment on a 16' screen.

Since there seems to be so little information and feedback on the internet about this projector, I'm wondering if one of Optomas other more popular projectors is close enough in specs. so that it's calibration adjustments might be similar.

Any feedback will be greatly appreciated.
