3D Ready Projection - 120hz sequential - GT700

Thread Starter 
I finally got 3D Bluray working using an HTPC on an Optoma GT700 projector.... I have to say that it is amazing 3D. The sharpest I've seen including the local cinema plex, I am running a 106" 16:9 screen.

The first thing you need to know is, if you have a 720p 3D Ready projector is that you have to have a product called 3D Vision from Nividia. This also means you have to use Nvidia graphics cards / GPU. Make sure you are using the latest drivers from Nvidia. This includes current downloads of the 3D vision software itself.

The second thing you need to know is that if your projector is not detected by the 3D Vision, you will need a spoof .inf file. There are instructions on how to do this, on these fourms and on the Nvidia forums, but I searched over on the Nvidia forums and found a person with the same projector I have that already created the file and had the link to his right on the post. Make sure you shutdown your PC after loading the spoofed .inf display driver file for your projector.

The third thing you need, is either Power DVD 10 Mark II software or Total
Media Theater with the 3D plugin.

Set your windows desktop resolution at 720p and your montior at 120hz.

This setup lets you use both DLP-Link glasses if your 3D Ready display is DLP, and / or 3D Vision glasses from Nvidia no matter what display your using. My pair of 3D Vision glasses we ate by my dog within 10 minutes of pulling them out. UUUHHGGG The last sacrifice needed to get it all working perhaps?

I'll try to upload the spoof .inf file that worked for me here this weekend some time.

As promised. Here is the .inf file for the 3D Vision and an Optoma GT700 3D ready 720p - 120hz projector. You just have to rename it from a .txt to a .inf

Cool.

Now, to be perfectly clear, I'd like to ask a few other questions:

1. This is the nVidia 3D Vision kit you're talking about, right? If so, how long is the emitter cable and what kind of connector does it have?

2. Which nVidia card are you using? Any other "gotchas" about the PC I should know about?

3. I need a longer throw projector, one that can fill a 110" screen from about 15' away. Are there any you're aware of, or have people only had success with the Optoma projectors?

4. Any links for others who have this working?

I shouldn't do this. I have a 63" 3D plasma. But, I might not be able to resist the allure of 3D projection. I'll try to restrain myself, but it might not work.

I hope this link answers more questions than it creates. I'll try not to overhype it, but I really like this product. There is also a tool on this page to determine whether your PC and display meets the requirements.

1. Yep, 3D Vision running on a GTX 470. Now, I had no clue what I was ordering, I wish it were a smaller lower end Nvidia card that would work just as well.

2. The GTX 470 is a monster, heat, size, takes two of my PCIe slots. the specs call for a beefy supply, I am running it on a high quality 450watt supply, the min spec is 550.

3. As long as it takes 720p - 120hz, I don't think there would be gotcha's. You have to either find a posted spoof .inf file, or the directions do not sound to techy to create your own. Keep in mind DLP-Link glasses of course only work with DLP displays.

4. http://forums.nvidia.com/index.php?s...70574&hl=gt700 The second post down is where I got the file. I'd assume he has it working as well.

D

It includes a 10' and 6' USB cable. Both are full size USB on one end and Mini USB on the other. Emitter and glasses (for charging) use Mini USB.

you have to use the nvidia route for now, but ATI also seem to have something up their sleeves http://www.digitalversus.com/3d-film...icle-1086.html

I'm hoping once 3D Blu-rays become more common (and they wont until the stuff needed for 3D becomes cheaper) we wont have to go though so many steps to get 3D working on projectors. I also hope that Optoma release their new hardware to watch 3D Blu-Ray they seem to keep mentioning or at least some news about it because that would make life a lot easier (if its not too expensive!).

Its good to hear the method works though! I certainly wont be investing in it for a good while. It would be so cool watching stuff in 3d on my optoma hd600x!

John,
Great work, your peresrvance finally played off.
Also great that you were able to use the X102 DLP-link glases and did not have to use an emitter or the glases that came with the Nvidia 3D player kit.

We screened Cloudy with a Chance of Meatballs Blu-ray 3D and the first two Pirates of the Carribean movies on DVD 2D to 3D converted last night for 9 people. I had to use 3 pair of Nvidia glasses. The emitter and Nvidia glasses do not work near as well as the DLP link glasses.

They (Nvidia glasses) lose sync every so often, especially if you look away briefly. They even shut off a couple a times. You only have to hit the button again, but still mildly distracting.

The DLP-Links glasses are solid, you can walk out of the room and walk back in without any note-able interruption. The X102's are really confortable, the Optoma DLP-link not so much, and the Nvidia were the least comfortable. You can lay down and watch too, very nice.

I think I'd have to work on placement of that Nvidia emitter to help with it some.

Some mild issues with the player softwares though.

Power DVD, only supports a handful of audio cards. I was lucky to get quality 2 channel out of it. If I use the transport controls even once, they won't auto go away again with a complete reboot.

Total Media Theater - Gives me full surround well enough, but at random it gives me the wrong aspect ratio or something where I have a small image in the middle of the screen.

If I use Power DVD, I have to reboot to get sound again in any other program or even windows.

Johnndenver:

Congratulations on your BR success with the NVIDIA/OPTOMA combination.

Does this seem to be a stable system? i.e. does it require any tweaking in between BR disks or from one day power off to the next day power on?

What else would be required to implement the 3D channels (ESPN 3d, etc.)? I have Directv with a soon to be ordered HR24 DVR.

To support Direct TV, you will need an Avermedia HDDVR Card, and an HDMI detective to go between your Direct TV and the Avermedia card to fool the Direct TV box into thinking it is one of the new 3D TV's. Comcast has no such display check, so it shoudl just run with out the HDMI detective / pirate box.

Hello John,

I hope you can answer my questions since i've been looking everywhere but I don't seem to find any explanation. Can you use the Optoma 3d glasses without the nvidia 3d vision kit/emitter? I have a 3d vision ready nvidia card but when I try to configure the 3d setting it asks to connect the emitter. I just order the optoma glasses but I'm afraid I wont be able to play games or watch movies without the nvidia 3d vision system?

Thanks in advance for your help,

Optoma pro 350

That is how Nvidia makes sure you purchased. 3D Vision will not run without the emitter.....

I have a couple. Make me an offer in PM.

I had a lot of fun over the weekend.

My theater is going into it's 5th year and we rarely have a lot of people over.

Including my wife and I we had 9 for Friday night and we had 7 for Saturday night.

I have read on here of those that give decent marks to the 2D to 3D conversion and I was as big of a skeptic as anybody. But I'll be darned, it is actually pretty darn good.

Screened Mega Shark -vs- Giant Octopuss Saturday night with the conversion and Avatar.... Avatar was really impressive with it, I can't wait fo rthe real 3D version to come out.

It sucks but yeah, only nvidia glasses work with the nvidia emmiter. this issue might be solved with nvidias 3dtv play though! http://www.engadget.com/2010/03/15/n...for-3d-vision/

I'm using the optical off my built into the motherboard sound card, so I am not sure.

I was getting two channel through to my projector when I was first testing only the HDMI hooked directly to the projector though. I don't think it's possble unless there is a cable that can split audio from video with one HDMI in and two HDMI outs.

If you can't get the HD codecs to work, is it really so terrible to use legacy digital audio? It's such a non big deal for me, I didn't even try it. I'm fine with the DD and DTS.

So JOHNnDENVER, which are you glasses of choice? and will they work with any DLP 3D ready projector (Optoma, Epson, etc)?

I'm only asking because I was only aware of the nvision 3d glasses that came with the "software". So now I believe that I would have to buy the nvidia card (GTX 460 personally), the Xonar card, the Nvision package and a 3D PJ along with these other glasses? Is this correct? Sorry if I sound like I didn't read the thread but I need reassurance.

I got 3D Bluray working this weekend with an ATI HD5770 and a set of DLP-Link Xpand x102 glasses on my H5360.

Not that happy with the glasses as the image is still somewhat washed out.

I am glad it worked for you, after a bit of puzzle it worked for me as well.

Few months ago I got optoma gt700, optoma DLP glasses and the first mac mini with HDMI. Only lately I was able to watch 3D. Problems along the way:

Mac OS do not support 120Hz output nor 3D, so u need windows. I installed windows 7, ult 64bit. After that I had installed stereoscopic player and managed to watch my first 3d at home, however software page-flipping buffer as implemented in stereoscopic player do not synchronize well, and depending on the movie resolution, switches eye synchronization from each few seconds to few minutes.

In spite of very convincing posts of Mathew Orman all around net there is a solution for this problem that doesn't involve buying nvidia 3d vision emitter, and that is emulating it. Here is the solution:

1. First you need 3D vision enabled drivers and 3d vision software. Apple provides nvidia drivers that do not have 3d vision support, so make sure you install custom 3d vision enable drivers. If you have mac mini, ask here and I give u a link.

2. You need to make sure that you monitor stays on 120Hz during 3D vision setup, therefor you need a custom monitor driver. The one provided in the second post did not work for me. You have to have edid overwrite option, so to make sure not to switch to native projector mode during 3D vision setup. I used Acer_H5360modded.inf. If you cannot find it, tell me and I will try to post it somewhere.

After that, grab the inf and replace the monitor driver, through updating the monitor drivers from device manager.

3. Emulate the usb emitter! This is done by some smart Russians, and solves a lot of problems. Here is a link to a blog: 3dvision-blog.com/forum/viewtopic.php?f=9&t=997

After that use any player, nvidia player that comes with 3D vision software or stereoscopic player with nvidia output, mount a blueray image with daemon tools and enjoy

Please replay wither this post helped you or I just waisted my time.

Without the emitter I only assume you would be using DLP Link glasses. On my GT720, DLP Link looks like ass. The image is too washed out and those glasses did not correct it. The DLP Link works fine on other PJ's I guess but not on mine. I'm happy with the 3D vision and Nvidia glasses. However, the price of knock off compatible Nvidia glasses are now $49.95 and honestly the quality looks better, IMHO.

Dang on the GT700? You would be hard pressed to detect any difference between X102's and 3D Vision glasses.

Can't imagine why they would be washed out at all on the 720.


But... I can now dump my HTPC all together as I just recieved my 3D-XL converter!!!! Yeah....


PS:
Gosh a quick search here and it seems like the GT720 and the X102 DLP-Link glasses is a popular configuration, so now I am really confused as to why your's would of produced a washed out image.

Not sure since I seem to be one of the only people that comment on the GT720 and mine came with the updated firmware (as it was a factory refurb ). But when I put the GT720 in DLP Link mode the image is washed out and I used those "ultra clear" style glasses. But like I said mine has the updated firmware and I didn't need to use the spoof file.

I got a stuck/dead pixel now. It's only 1 and it's slightly annoying. I put in an email request for repair at a store I found online and I have already tried that java app to fix dead pixels but it didn't work. If the repair cost is too much I'm just going to get a different projector.

I got my eye on this PJ: InFocus IN146 DLP Projector

Sorry to hear this. Isn't the 720 still under warranty? That unit seems to be pricey for what it is and the max res is well....not sure. Where is your bad pixel located? What does Optoma say?

I don't think it's under warranty. It was a refurb unit off of ebay. I'm sure it only had (30,60 or 90) day warranty. It's already been 5 months.

Optoma has an option for owners to provide proof of purchase and serial number + give them a credit card number (just in case ) and they'll send another refurb unit while you send yours in. You have 15 days to do so otherwise they charge your CC for the full price. I'm willing wager that this is similar to Microsoft and their Xbox 360 RROD policy. If your Xbox is still under warranty and you get a RROD they will send you a replacement (refurb) unit - instead of repairing yours. I don't like this deal. I'd rather have my unit - and have it fixed.

Anyhow, since I posted this, I found 1 more dead pixel. I think I may just retire this 3D thing. I invested too much money on this project and I've had nothing but troubles from the get go.
