I've never heard of DLP projectors utilizing wobulation or checkerboard like DLP TVs. 3D is much more straightforward in a DLP projector: a full resolution right image is displayed, followed by a left one, then right, etc, with DLP link flashes in between. You definitely get full 720p per eye with this projector. Is it better than 1080p checkerboard? I don't know, but the pixel count is roughly the same. 720p is 1 million pixels, 1080p is 2 million, so 1080p checkerboard is 1 million, but there's probably some advantages and disadvantages to the checkerboard layout.

Even worse if your source is not 1080p, it's being scaled twice - first by your computer to 1080p and then back down to 720p by the projector.

I was initially concerned about the scaling/rescaling issue, too, but I've run at 1080/60, 720/60, and 720/120 and can't tell a difference when watching HD or SD material. For me, the advantage is being able to use much more desktop real estate at 1080, as I wind up doing a lot of futzing around on the PC. If there's a PQ impact from feeding the PJ 1080 versus native rez, I can't see it -- but maybe that's just me.

Also, I, too saw a fair amount of rainbow during the first hours of using the PJ (first DLP). However, like you, either I became accustomed to it or the PJ calmed down quickly because now it's pretty rare that I notice anything.

I don't think you're seeing 1080p. The projector is digital and can only display at one resolution. If it receives anything else, it will scale up or down.

That's not to say that Windows might be doing a better job at screen management at 1080, and then the scaled down to 720 looks better than setting Windows at 720. I'll try this later.

Can also confirm "white spots" on my H5360 projector. These are stuck mirrors not dust blobs, as I can focus the lens to make them appear as pixel sized squares on the screen.

Am suspecting there was a bad batch of H5360's built prior to December 2010 (my manufacture date).

Like others, I purchased around March 2011 and am now 1 month out of the 1 year warranty.

Oh, I know. I realize no matter what, the image is only going to be 1280x720. But with the desktop set to 1920x1080, I have a lot more area to work with. Text is still readable, so it works for me. YMMV

I dont have the options : Saturation / Tint / Sharpness in the option MENU ?

Im using DVI to HDMI converter from my graphics card to the PJ !

Is this the reason ?

What if i use the MINI hdmi port on the graphics card to the PJ will that solve the problem ?
post #1537 of 1760
^^ I think those options are only available for analog inputs.

Been going through this thread, but don't recall coming across what I'm curious about.

Can the Acer be run at 120hz in 2D mode (via HTPC, of course) with no frame drops whatsoever?

I hinted at it in my last post. You can run in 2D@120Hz such that 24p content can be shown without 3:2 pulldown judder.

I have the same problem and i think its because i have been smoking too close to the projector. If i follow your instructions will i be able to get rid of the dust blobs because they are replicating pretty quick taking over my screen. Please advise.
PS: Im pretty good at DIY!

You will not have saturation and hue while feeding the H5360 RGB video which is what most pc graphics cards default too. Try setting the graphics card to xvYCC color video and you should get the saturation and hue to return in the projector menu. Sharpness is in a different menu and should be there even in RGB mode. At least I think it is...will have to check to make sure. I never noticed it missing.

Just looked at the manual...computer mode and dvi mode: no sharpness, saturation or tint/hue. The DVI connection itself may stop you from using anything but RGB. I have a DVDO Duo so I can select what the output is plus its an HDMI connection between the projector and my Duo. My PC is connected to my Duo and Duo the projector via HDMI. Although if I select RGB color out from my Duo I lose saturation and tint.

Hi Ron ... :0)

I want to thank you for this !

I changed it to 'YCbCr' and now i have all options.

Suddenly games and movies looks sharp and im very happy :0)

Games and movies where blurred when using RGB from the PC, and i couldnt get the picture right. Now its all sharp and crisp :0)

This PJ is a great deal for the money :0)

Thanks ... !

Great news! Yeah I am pretty happy with this little projector for 3D playback too. It really is a good deal.

Last week I tried calibrating grey scale through the Monster 3D RF glasses and boy what a difference that made. I was able to get very low DE's. Most under a DE of 1. Degamma set to 1 yields a nice smooth gamma of about 2.3. Gamut wasn't the greatest but not as bad as the older JVC's that had horrible greens and yellows. Lowering saturation to 43 worked well for my setup. With grey scale and gamma set near perfect through the glasses the 3D image quality went way up. I can live with this projector for 3D for a long while. I even calibrated 2D grey scale and it looks a lot better but the amazing light output of this little projector makes blacks too grey for me. I use my JVC for 2D so no issue. Brightness is plenty in 3D and blacks don't look bad in 3D. Also want to note that the bulb has over 100 hours on it but still plenty bright in 3D in eco lamp mode.

You also need a 3D converter to convert all the 3D formats to frame sequential 120fps. Optima and VIP make them.

So could this be done with the Optoma GT750 if used with the Monster/Optoma RF glasses ? Is it a piece of software writen specifically for the Monster/Optoma RF glasses that allows you to do this ? Or is there no special software needed, and you just need to wear the glasses while calibrating the grey scale using the projectors own onboard calibration tools ? If the latter, could you then also do this with other projectors that use DLP link glasses and not RF ?

I have a DVDO Duo video processor with test screens and Chromapure software with an i1 Display 3 pro colormeter. I measured through the glasses. I did not have the shutter glasses active but I fail to see why that should make a difference. The RF glasses are set to to 105% duty cycle when active because DLP refreshes so quickly. Plus looking at a black and white image before the glasses are active and after I don't see a grey scale color shift.

I watched some of my IMAX films tonight in 3D. All I can say is wow! Color balance looks wonderful in 3D now.

You should be able to do the same with the Optoma if you have the tools to calibrate color.
post #1551 of 1760
Also want to point out I used the color offsets in the projector. My Duo can not process 3D video. It just bypasses it. So the test patterns were 2D but measured through the glasses.
post #1552 of 1760
Thanks Ronomy, thats great.
It's nice to know 3d color can be calibrated to look as natural as 2D.

Hey Ronomy, let me ask one more thing.
3D being "darker" is not so much what bothers me. What bothers me, is that the glasses make the color look wrong not that the image gets darker with the glasses on.
So after you do your calibration to 3D is the color then correct looking even though it may be darker ?
What I mean is, a 2D picture can be dark but have correct looking color. Is that what you now get with 3D ? It may be darker than the 2D image but the color still look as correct as the 2D image only darker ?

Yes! Color fidelity will look the same as 2D after you calibrate the image coming off the screen but measurement taken through the glasses. The glasses are not neutral in color and each manufacturer will be different so be sure to buy all the same model glasses. That way after you calibrate all people will see the coreected image.

I watched the IMAX film 3D Hubble and 3D international space station last night and its the best my Acer H5360 ever looked. Before doing this calibration I was always playing with the controls because color never looked right.

You will need to calibrate the projector for both 2D and 3D then save separate configs because the image will not look right with 2D after you calibrate through the glasses. So you can't use one config for both.

Ron

Thanks again Ronomy,
I have read about people wanting to do it or going to do it, but I think your's is the first post I have come accross with someone that really did do a full-on 3d color correction.

The new Display 3 color meter is very good at taking low lumen measurements so before getting this new meter I don't think I would have had very good results through the glasses with light coming from the screen. So yeah I am very happy with the results.
post #1556 of 1760
I have looked over budget 720p projectors and i think Im ready to pull the trigger on the h5360. Although I can't seem to find a website that looks reputable to buy bulbs. Can you guys refer me to any that you have used?
post #1557 of 1760
i see that sears.com has them but people keep saying there not the right ones. but its there. and i am sure they would get in trouble if they were selling botched items. other than that there appears to several lamp sites. like pureglare and apexlamps and more but i don't know the credibility of this sites. also amazon has it on a account called electrified. and sold directly from amazon, there's this(i think this is the model) http://www.amazon.com/Acer-EC-K0700-.../dp/B00392CI2Y

My projector has recently started showing stuck mirrors. A month or so ago I had one stuck black pixel that showed up then went away for a while. It came back last week, along with a white pixel. Now I have 5 white pixels and a black pixel. I bought this thing back in November of 2010, so I'm quite past the Acer warranty period. Currently at hour #2562, almost entirely Eco mode. Also I occasionally get a bit of a flicker that goes away if I run with Eco mode turned off for a bit.

Anyway, I remember a while back some people talked about dealing directly with Texas Instruments about the DMD chip, as they warranty it for 5 years. Any news on that effort?

Acer H5360 NOT WORKING WITH POWERDVD 12

I'm new to this forum because I just bought the Acer H5360 projector and can't seem to get it set up to play 3D videos (SBS) off my harddrive (mkv format), using PowerDVD 12. I've written to PowerDVD support and haven't heard back as yet. Here's what I wrote:

My system has an Intel i7 processor, EVGA Geforce GTX560 Ti video card with the updated Nvidia 301.42 driver, Windows 7 Professional, Nvidia 3D Vision 2 IR and glasses and the Acer h5360 projector connected with an HDMI cable.

In both the Nvidia Control Panel and the Windows Screen Resolution, I've tried to set the projector to 120 Hz and 1280 x 720. As well, the projector itself has been set to Nvidia 3d display.

When I attempt to watch a SBS video in PowerDVD, it seems I have to force the Nvidia IR to 3D "on" and then it shows me a 2D picture through the right lens of the Nvidia 3D glasses while the left lens has an extremely dark picture in 2d (actually, the left lens is almost blacked out). In effect, there is no 3D. The same thing happens when I try to view a 3D photo. While Windows Screen Resolution shows 120 Hz on "Advanced settings -- Monitor -- Generic PnP Monitor", the PowerDVD result is as if the Acer is really projecting at 60 Hz, instead of 120 Hz.

While playing a video in PowerDVD I believe I've attempted to try each of the various 3D options using the down arrow tab next to 3D when 3D is enabled. It doesn't appear there are many options to change in that menu and within PowerDVD itself.

The Acer projector and rest of my hardware does work fine in the Nvidia control panel (displaying their test videos in 3D), in the Nvidia 3d Vision Photo Viewer (again, seeing 3D photos) and playing an arcade style flight game called "Skydrift".

Any ideas of something/anything I could try would be really welcomed !!!!!
