Can somebody answer my question?

How does the HD 25 compare to the HD 33? Any major differences?

Plus it would be hanging right in the middle of the room's ceiling and very noticeable.

The Optoma is mounted directly above a ceiling fan and directly below the ceiling hole/cabling, so it turned out to be an almost perfect replacement for my Pro8200.

Understood

My setup would be as follows,

i'm putting the projector in my room (not too big, 10' by 14') which i can get to about 5fl during the day (1fl at night) so quite dark [for a room that was never really designed for anything like this] My main concern is that the maximum throw i can get is 9 ft, at this distance the projected screen will be 83" diagonally. I havn't found any user experiences i can relate to on the internet with this projector at that close a range. I've read that it is a particularly bright projector, maybe even too bright? should i have any concerns at having such a small projected screen?

cheers for any help given

You may not get an answer unless someone else here happens to have a similar setup (which is unlikely). You do know there are a few dealers that have generous 30 day return periods for projectors? It might be worth it to try one out and return it if it doesn't work for you.

My HD25 was a demo unit from Projector People that was marked down to $899. Someone had ran it for less than an hour and decided it wasn't right for them.

I own both the HD25-LV and HD33 and did a split screen comparison.
The 25 LV is about half the size of the 33, has better black level, RGBCYM color management, DC3 vs DC2 in the 33.
25 has only two user memories. The 3D mode user settings are maintained in one. If you change the settings in any other 2d mode (Cinema, Bright, etc) the settings are saved in the 2d user mode.
33 has frame interpolation, the 25 does not.
The 3d refresh rate in the 25 is 144 Hz, the 33 is 120Hz.

In regard to the DC3 vs DC2, can you see obvious improvement in fine color gradients in which the DC3 is suppose to be better: showing fewer 'steps' in between. 95% of the time my 33 looks great. It's only when scenes of fine color gradients in movies, tv shows, commercials, etc. that really get my attention in their coarseness or posterization. I had a 92" Mits Rear Projection HDTV with DC3 is it appeared to be better than the DC2 Samsung I had previously to it.

Thank you for posting the information above.

Thanks for that!

So which projector would you recommend then? Does the added frame interpolation of the 33 make a big difference?

tucson,
Need your experience on 3D for both of these..

HD33 with FI(with Pure Engine equipped), but 120Hz
HD25 no FI, but 144Hz, does its 3D quality compensate the FI like 33?

Came accross a few posts in forum that they feel very mild/slightly uncomfortable or eye fatigue with 25 (without FI) compared with 33 with FI, after watching a certain amount of time, say probably 30mins.
What's your take in this?

And how about the 3D depth, effect, detachment of object.. appears to your eyes between 'em?
post #218 of 556
Sorry to "jump in" and drop a new question, but I am really needing a piece of information about this projector...

Is it possible to shift the image (such as for a 2.35 AR movie) inside of the 16:9 image area? I like to mask at the bottom (partially retract screen), and move a 2.35 image to the top of the screen.

From the manual it looks like it does support this shift in HDMI mode.

Anyone know for sure?

Thanks!

The question of BenQ W1070 and HD25 comes up pretty often, so I did a review of both. I figure if some of you don't visit the BenQ W1070 officla thread you may benefit from this link: http://www.avsforum.com/t/1435626/benq-w1070-dlp-full-hd-3d-ready-with-lens-shift-for-1000/5310#post_23478413

Pretty good review, thanks. I might add the Optoma does have a "super wide" feature that some might find useful. Did you find either remote to be better than the other?

I've used the BenQ remote previously but quickly found it's rather useless for my purposes. Didn't even unpack the HD25 remote. These aren't permanently mounted yet, so I didn't see a need for it. I'm the type to set it and forget it. I don't tweak settings after I've spent time on it once nor do I recalibrate/change settings for different content. Not that picky, I just want it to be good enough. I won't notice a slight improvement as much as I'll notice a slight imperfection.

I'm not familiar with the "super wide" feature... what does it do and who would it be useful for?

I find the 3D on the 25 better but I can't explain why. The lack of FI on the 2d side can be an issue but tests on the 33 using the Spears and Munsil disk show the FI is dependent on the speed of objects, so isn't 100% effective all the time.
Not sure if FI on the 33 was active in 3d mode.
I am still playing around with different settings. Also I see there's a firmware update for the 25. I will call Optoma next week to see if they know anything about it.
I just measured the gamut on both and the 33 wins in that arena. Green is a bit weak on the 25. Don't know if its my 25 or a common issue.

Can't say it's better or worse than the 33 as far as the gradient. We're still dealing with 8 bits per color so I guess it's up to the processor in the PJ. I still have my 2007 RP Samsung DLP and it had bad banding during some commercials.
There's just something about the 25LV that sets it out a bit from the 33. Even with both calibrated to the same test disk the 25 seemed to have more presence, or pop, or something.

Will this PJ do 1080P SBS via PC?

If you mean "Can I hook a PC up to the HD25 and watch 1080P SBS videos using software?" then yes, you can.
post #226 of 556
Does the HD25 display 24fps SBS 3-D properly.. without any overt 3-D motion artifacts?

The HD33 with SBS 24fps 3D content shows nasty 3-D phasing artifacts. The only way to correct this (with the HD33) is to feed all SBS content as 1080p/60fps.
post #227 of 556
How would I recognize the 3d 'phasing' artifacts you describe?

I played a few hours of trackmania2 stadium last night in 1080p side-by-side, but that was all at 60hz... can't think of a reason I'd want to use 24hz side-by-side?? what source are you using where 60hz side-by-side or 24hz framepacked aren't better anyway?

(edit) - ok, looked up the phasing stuff you were talking about in the hd33 thread, sounds nasty. I don't use any of the devices that use that mode, but I'll manually put my pc in 24hz mode this afternoon and try it with stereoscopic player or something.

A 3-D phasing artifact is almost as if one of left or right cameras has a misaligned shutter. They are in sync, but during any type of movement, you can see artifacts. Artifacts that can be easily seen when viewed in 3-D. In this case 24fps (ala: 23.976) content when shown in SBS 3-D on the HD33. By altering the framerate with an added pulldown cadence. a 1080i or 1080p SBS 3D source will remove this phasing artifact on the HD33.

Videogames are fine at 1080p/60, as they can still be native at that framerate, but virtually ALL of the major features are native 24fps (23.976). Something that Optoma missed for their SBS/TnB 3-D mode.

Any home or pro shot 3-D video footage that one wishes to make a 3-D bluray will need to be 24fps if one wishes to use the 1080p 3-D bluray format. When I am editing in that format, I can output side by side while I edit. I would prefer that be viewed at 24fps, and not a modified/altered 60fps.

Going back to thoser major Hollywood features that are all essentially native 24fps. - For 1080i content, many devices (set top boxes, receivers, etc) can detect and do 3-2 pulldown for a superior 1080p image. Which works great for standard 2D material. It should work equally great for SBS 3-D content. Except - the HD33 doesn't work correctly with 24fps/SBS 3-D content. Any type of features like this need deactivated when using SBS 3-D content with the HD33. ALL of my Comcast 3-D Ondemand channels are SBS 3-D. Ditto for many of the streaming services.

My other 3DTVs handle SBS 24fps 3-D content just fine. The Optoma HD33 has, plain and simple, a design flaw in their SBS 3-D mode.

Hi Kraine,

In the review above, under the section for "Results outlet box with the default settings", the translation mentions something catastrophic with the calibration, and that it must be done manually for this projector...

I am looking to purchase this as my first projector, and I know nothing about calibrating. Is this something I can do easily, or do I need some special equipment to calibrate the projector correctly?
post #230 of 556
TusconDave,

Are you happy with your LV? Sargeant had issues with his, but I think I read you like yours. Did you have difficulty calibrating it?

Tried 1080p/24hz video mode and played a video from stereoscopic player in 3d side-by-side mode. Looked fine (coudln't stand the mouse jerkiness you get at 24hz, but that's to be expected I think smile.gif ). From reading the hd33 thread, it sounds like the 1080p/24 sbs issue was pretty hard to miss, right? If so, it seems to be a non-issue with the hd25...
post #232 of 556
Thanks for the detailed report back, Defiancecp! That is very good to hear.

From what I've heard, the HD25 runs at 144hz for 3D (the same rate as Real-D theatrical) while the HD33 runs at 120hz for 3D. Is this correct?

If so, what DLP-Link 3-D glasses work with 144hz? I know the BenQ glasses do, but didn't know if anyone has made a somewhat complete list of the other DLP glasses out there..

I recently purchased the HD25-LV and I like it alot with the exception of one issue. I currently have the projector on a table until I finish the ceiling mount and if you put up the test grid the image is strait and flat at the bottom but as you go up the image it curves more and more towards the upper corners (see images below). If you align the top corners with the screen frame the top center of the image is more than a 1/2" (14mm-16mm) below the frame edge. This is not and issue with the screen as it is flat, I have no keystone correction applied and have it at the correct offset (9" for my 120" screen). Is anyone else seeing this with the HD25 or the HD25-LV?

On another note I have read through most of the threads in regards to the HD25 and HD25-LV and there was some questions as to if the HD25-LV is brighter than the HD25 in 3D mode. I called Optoma tech support yesterday regarding this and according to them they are the same brightness in 3D. I asked if they have any documention showing this but they did not.

It seems the nature of HD25, now perhaps HD25LV too..

Thanks to Oris's good reviews, refer to the link below,

While W1070 is slightly better in this.

As to the brightness comparison.. if only you can compare them side by side... sigh
If not brightness difference, what is the difference between these 2 guys?
post #236 of 556
Could someone do me a huge favor and check this in the 3D settings... I've read that the HD25 allows you to chose the left or right image when playing 3D, meaning you wouldn't need a separate piece of hardware to do passive but instead just an HDMI splitter.
post #237 of 556
Any owners of the HD25 use this with a HTPC? I currently have this projector on my short list to buy and curious if there are any issues when hooking this up to a HTPC. I use my htpc for viewing blu-ray rips via MPC-HC and watch cable tv. I also have an xbox 360 for gaming.
post #238 of 556
Left/right options are there. That doesn't necessarily mean it's a good choice for passive still, though; without lens shift alignment is a Beotch smile.gif I'd personally still pay for the external hardware just to get a lens shift proj.

Works fine with my htpc.

Another question would be if the left or right eye is selected, would this option need to be re-selected whenever going back into the 3D mode, or when the PJ is fired back up?

Regarding the DLP Link glasses vs the RF glasses, does anyone know if the RF glasses would also be 144Hz? I think i found an Optoma RF emitter manual online, and it seems the 144 Hz is set by the projector. Am I correct in my understanding? Debating between the BenQ W1070 and the Optoma, with the Optoma having the edge because of the supposed benefit of having a VESA port. I like the idea of RF glasses not losing sync if I look away at the screen to grab a snack or something, but I would have a hard time justifying the extra cost if the difference in contrast is somehow hindered by something I'm unaware of with RF glasses.
