Warning to ALL 3D people who want to purchase a VGA Projector..
Hey All,
I am here to Warn anybody and hopefully we can get the word out and whomever is responsible for this oversight can possibly correct this Problem..
I had ordered 3 used Acer X1261P NVidia Certified DLP 3D PRojectors and found out the hard was that it is IMPOSSIBLE to Connect to a 6xx series and newer Video cards by Any Manufacturer..
The Problem is the newer video cards been replacing the DVI-I with a DVI-D connector.. The "I" designation makes it BOTH Analog and digital.. The "D" Designation is Digital and if you know anything about this you can NOT USe a Digital signal into an analog one..
Well you say why not use a adapter Sorry they do NOT work. well you say why not use an Active Converter one small problem with that as well is ALL the Converters I found ONLY Pass 60hz and as we all know 3D needs 120hz..
So there is ONLY 2 Solutions and here they are:
1. With the newer 6xx, 7xx series card is to TRI SLI..
2. Use an older 5xx series or below card ie,, 590GTX or 2 580GTX. they have the required ports still
Now I do NOT know who is responsible for this but I can ONLY think NVidia is Totally responsible for this Oversight.. I know they have to Certify all the 3D Equipment and I am unsre how they expect people to connect these VGA (Analog PRojectors with Digital Outputs??
So this is a warning and the Fix for the Analog Projectors.. IF you need any clarification Please post here and I can give you the Facts which all I can currently think of are here..
The NVidia configuration wizard is WRONG.. IT stated I could use the DVI ports and the Display port which the 1 DVI port is impossible to connect too..
I wish I could have 10 minutes with the Head Guy who certifies all the equipment and show them this oversight..

Hi,
It's worrying (but not a shock) if they are slowly dropping DVI-I connectors.
The GTX690 has 2x DVI-D and 1x DVI-I so I don't think it's an issue for me and there are probably other non-reference models that have different output configurations.
You've made a very good point about DVI-D and DVI-I. I was caught out when buying a long DVI cable as well, as the DVI-I cables are much more expensive as they carry the extra connectors for the analog signal.

I think the more ridiculous aspect is these projector manufacturers are releasing new models that still don't have DVI-D inputs. Latest projectors can do 1080p 3D. And can do 120hz. But can't do 1080p 3D @120hz because they only use analog PC inputs and bandwidth starved HDMI controllers.
I get what you're saying though, OP. It's a good issue to point out. Never even thought about this. And certainly is an issue for people who have older projectors, but need/want to upgrade their GPU.

My monitors (3D Vision 1 monitors) have ONLY a DVI-D connection. I am not even aware of any 3D Vision monitors having a DVI-I connector...
I don't know about projectors but I suspect the Analog component is not required for 3D Vision to work only the digital part.
Hope the guide helps you

What he's saying is that the current cards are dropping analog support and that there are certain projectors that only have analog inputs.
3D vision works perfectly fine over VGA, so it's definitely something to be aware of.
It's a bit tragic that none of the consumer grade projectors have dual link DVI connectors. At some point in the future, HDMI 2.0 will address the 1080p 3d @ 60Hz issue, but until then it sounds like our options are becoming even more limited.

I am not talking about VGA connectors. That I know and have used before (with 3D Vision projectors) What I was talking was about about the DVI connector. I wasn't aware that some connectors require the DVI-I and are not working on DVI-D connectors...
This is sad indeed to drop support like that

i second the fact that it is not true of all 600 series cards. i personally use Gigabyte 660ti oc in sli (x2) and both cards have a DVI-I connection which translates into VGA just fine with the right adapter (my projector is viewsonic PJD 6223).
but true this may be something to be checked carefully when buying a graphic card.

OK not trying to pick an internet fight but I don't think you guys know what a DVI- "I+ Connector looks like.. I think you are confusing it with a DVI- "D" connector..
Just to State my case I looked at a 660GTX Ti and it stated this and I quote:
"
Add to Comparison List
GV-N66TOC-3GD
•Powered by NVIDIA GeForce GTX 660 Ti GPU
•Integrated with the first 3072MB GDDR5 memory and 192-bit memory interface

As you can Clearly see in where it says this "Features Dual Link DVI- "I_ / DVI- "D" / HDMI and Display port...
[url]http://www.playtool.com/pages/dvicompat/dviconnscables.jpg[/url]
They are VERY Similar but if you look at the DVI- I connector on the Top Right, Notice the Plus on the left side and the 4 Holes around it, well that is the ANALOG PArt.. Now look at the DVI- D connector on the left. and the 4 holes on the left Around the Plus are gone..
That is the difference and I guess this confirms just How easy it is to be mistaken about the connectors I know I was.. ;)
Basically I am just trying to educate the masses and I am being shot down .. Please really read this and look at the pics I posted you can clearly see the difference if you look close and not just a quick look..
I assumed they still used the same plugs and I was wrong just trying to let everybody know NVidia is Dropping Analog Support time to move on and go Digital..

Often the connector listings on sites like Newegg are wrong.
GPUs very from manufacturer to manufacturer, from revision to revision. So the only way to be sure is to check the manufacturer product page.
You can blame "Analog Sunset"/HDCP for VGA getting the Stepchild treatment.
No-one's trying to shoot you down at all!
It's a very good post and I understand exactly what you're talking about, having been there before myself.
For example:
http://www.hardwareheaven.com/reviewimages/nvidia-geforce-gtx-690/nvidia-geforce-gtx-690_outputs.jpg
Just saying there are exceptions with certain (mainly non-reference) boards.
Had me worried, so I went to look at the card I'm considering, a GTX 780 from EVGA.
I'm not disputing that analog is on it's way out. But at least for current gen, it's still possible.
Using your terrific pictures, I went to look at connector specs here:
[url]http://www.evga.com/Products/Product.aspx?pn=03G-P4-2782-KR[/url]
Here is the backplate for that new GTX 780:
[img]http://www.evga.com/products/images/gallery/03G-P4-2782-KR_XL_5.jpg[/img]
So, please correct me if wrong, but this card is supporting DVI-I, and clearly has the + sign connector for analog.
Good luck whatever you decide. You need to really look at the economics though, it might be better to buy newer projectors in the long term.
I don't know the specifics of your configuration, but with longer cable runs I found that analog does degrade significantly and I never achieved the pin sharp image I really wanted.
I've got a feeling that you can't achieve what you want with a single 690 either, as there are all sorts of limitations about what ports you can use in conjunction with others.

Yes From what I can tell Depending on if I can use the 2 Bottom ports as I thought you at least had to use the top main one first??
I am not going with a new Setup just getting very expensive the wall plates I need and cables are going to be near 250 bucks. the Projectors are 500 each and I will probally need a 680GTX or a 770GTX at the lease to run 3840x720..
I am just going to try and locate a 590 and get two more of the Acer 1261P's for now.. THNX for the help..
I will look into this another time as I have another Project already lined up to get 3D in my Home Theater starting this January..

Thanks for pointing out some pitfalls to keep an eye on. Hadn't even occurred to me before.
If you only need 3 analog connectors, maybe it's worth looking into some cheaper video cards to just provide the analog connection. You could run your primary gaming card, and another video card that was not for gaming, just to provide analog desk space. Not certain that would work for gaming, but you'd be able to stretch across all three projectors at the desktop.
That approach might be easier/better than trying to get 3 analog connectors on a single card.
Same sort of idea might hold for any card you can find with 2 analog connections. If you SLI those two, you'd have the three analog connections you need.
Sounds like a great setup. Good luck.

That is the difference and I guess this confirms just How easy it is to be mistaken about the connectors I know I was.. ;)
Basically I am just trying to educate the masses and I am being shot down .. Please really read this and look at the pics I posted you can clearly see the difference if you look close and not just a quick look..
I assumed they still used the same plugs and I was wrong just trying to let everybody know NVidia is Dropping Analog Support time to move on and go Digital..

GPUs very from manufacturer to manufacturer, from revision to revision. So the only way to be sure is to check the manufacturer product page.
You can blame "Analog Sunset"/HDCP for VGA getting the Stepchild treatment.
It's a very good post and I understand exactly what you're talking about, having been there before myself.
For example:

Just saying there are exceptions with certain (mainly non-reference) boards.

I'm not disputing that analog is on it's way out. But at least for current gen, it's still possible.
Using your terrific pictures, I went to look at connector specs here:

Here is the backplate for that new GTX 780:
So, please correct me if wrong, but this card is supporting DVI-I, and clearly has the + sign connector for analog.

I will look into the 690..

I don't know the specifics of your configuration, but with longer cable runs I found that analog does degrade significantly and I never achieved the pin sharp image I really wanted.
I've got a feeling that you can't achieve what you want with a single 690 either, as there are all sorts of limitations about what ports you can use in conjunction with others.

I am not going with a new Setup just getting very expensive the wall plates I need and cables are going to be near 250 bucks. the Projectors are 500 each and I will probally need a 680GTX or a 770GTX at the lease to run 3840x720..
I am just going to try and locate a 590 and get two more of the Acer 1261P's for now.. THNX for the help..
I will look into this another time as I have another Project already lined up to get 3D in my Home Theater starting this January..

If you only need 3 analog connectors, maybe it's worth looking into some cheaper video cards to just provide the analog connection. You could run your primary gaming card, and another video card that was not for gaming, just to provide analog desk space. Not certain that would work for gaming, but you'd be able to stretch across all three projectors at the desktop.
That approach might be easier/better than trying to get 3 analog connectors on a single card.
Same sort of idea might hold for any card you can find with 2 analog connections. If you SLI those two, you'd have the three analog connections you need.
Sounds like a great setup. Good luck.
