Asus VG278H Issue Displayport to Dual-Link DVI Adaptor
Hi,

I have just purchased an Asus VG278H. Due to the lack of Dual-Link DVI port on my laptop I am using a Displayport to Dual-Link DVI adaptor.

I cannot get 3D to work. The LED at the monitor IR emitter does not light up. I have read that some copies of monitor have a hardware issue with a disconnected emitter. This is not the case here as this error is not reported at the monitor information menu.

All the drivers are installed. However I have noticed in Device Manager the monitor is listed as generic PnP Monitor. Is this normal? As I am suspecting the use of the Dual-Link DVI adaptor may be the cause of the issue here.

Any ideas? :(

Many thanks!

The monitor MUST be recognized or 3D will not enable, generic pnp will not work.

Do you have a second monitor connected, if yes, disconnect it.

Also if you do use 2 monitors, the 3D monitor must be connected to the Primary Output of your GPU.

You can go to device manager and unistall the monitor driver. Then at "Your Own Risk" hotplug the monitor. Your computer should detect it as a new device and register the correct EDID.

Or download Monitor Asset Manager, extract the real time EDID info, save it as an .inf file, then perform an EDID overrride.

These are DESKTOP instructions, I'm unsure how to proceed with a laptop. So you may not want to try any of this.

On a laptop, I think you must disable the integrated display, then.......?

Thank you for your swift reply sir. This is my set up:

Dell M4600 (Quadro 1000M) -> Advanced E-Port Replicator
Advanced E-Port Replicator Video 1 Displayport -> Startech Displayport to Dual-Link DVI Active Converter -> Asus VG278H
Advanced E-Port Replicator Video 2 Single-Link DVI -> Dell E248WFP
Laptop integrated display shut (lid down)

I look into the methods you've suggested when I get home from work.

Many thinks.

Looking at the pic on Newegg of the packaging contents, it shows 2 Discs. Is one of these Discs the Driver installer, if so you need to use it, it will install the EDID of the Display. Once again, the integrated Display needs to be disabled and the Asus set as your Primary monitor. <----as far as I know, I have no 3D laptop experience.

One other thing, make sure you enable the full power/full performance in the power saving settings menu.

I have tried the EDID override method. The monitor is now recognised correctly as VG278H.

No avail so I attempted to reinstall an older driver from the CD as other's have reported 3D not working after updating driver.

From the original CD (275.97) it tells me 'NVIDIA Installer cannot continue' 'This graphics driver could not find compatible graphics hardware.'

Confused. :-(

Thanks for reply.

There's a sticky for laptops, several users posted that they needed to update their bios for the newer drivers. Read thru it and see if it helps.

At least your display is recognized, that's a step in the right direction.

Do you mean this thread?

http://forums.nvidia.com/index.php?showtopic=203162

The Stereoscopic 3D options are enabled. The monitor is running at 120Hz. The emitter LED is not showing and thus not syncing with the glasses.

One step at a time! I will get there!

Yes, that was the thread.

BTW anyone reading the original post and wondering what is meant by not having the red warning refer to this article
http://3dvision-blog.com/problems-with-asus-vg278h-3d-monitor-and-the-integrated-ir-emitter/

Are you getting 120Hz and a double image in the game? Can you cycle control+t, turning 3D off and on?
If so, the GPU is seeing the Display. I'm uncertain that this implies that it sees the internal emitter. On an external emitter, 3D Vision will not enable unless the GPU sees it as well as the display.
It may be possible that the GPU only looks for the EDID on that display and assumes the emitter as a given.
Also, if you are getting 120Hz to the monitor, we can assume the adapter is OK, I think.
You,ve confirmed 120Hz at the monitor, right? Not just that the GPU wants to send 120Hz.

I can confirm the monitor is at 120Hz when in 3D mode. I looked on the information tab on the OSD of the monitor. When not in 3D mode it's 60Hz. When I enable Stereoscopic 3D it's 120Hz.

I can see the double vision in the game. It is just the emitter (no LED indication) not syncing with the glasses. I can confirm the glasses are charged and on (no school boy error there). Even when the monitor was detected as PnP the double vision was working.

Thank you for your help. Much appreciated.

Can the emitter be enabled/disabled in the menu? Is it set to off? The only thing I saw in the user manual was about adjusting signal strength.
3D IR Mode: Select output power for the built-in IR emitter.
Select “LAN Party” for an environment with multiple IR emitters
to prevent mutual interference. Select “Consumer compatible”
for a longer distance positioning.

Maybe it has something to do with the Quadro card. I'm unsure, but I thought they had a drop down menu for selecting Display type as well as the type of 3D glasses and emitter being used.
Never had one, only seen pics sometime ago.

When installing drivers are you installing Quadro drivers and not GTX drivers? http://www.nvidia.com/Download/index.aspx?lang=en-us

You might want to try the Option 2: Automatically find drivers for my NVIDIA products

Found the pics I was thinking of, not sure if these pics are representative of notebook GPUs as well.

The 3D IR Mode and NVIDIA Lightboost options are both greyed out. I have tried using different Splendid Modes.

I am using the latest driver for my GPU; 285.62 for Quadro 1000M.

You may need to open a support ticket with Asus and/or Nvidia.

Wish I could be of more help, I'm lost on Quadros and laptops.

While the emitter will not show up in device manager, because it is integrated in the display. I do believe that the emitter driver should show up in the list of processes in the windows task manager.

I did come across a page that says "NVIDIA 3D VISION USB DRIVER FOR QUADRO"
Version: 258.49 3D Vision USB Driver
Release Date: 2010.07.05
http://www.nvidia.com/object/quadro-3d-vision-usbdriver-258.49-driver.html

But I know older USB/emitter drivers will not work with a newer graphics driver version on "GTX" cards, they must be the same version.
Starting with version 275.xx or there abouts, the USB driver started being bundled in the GTX driver package.
I'm unsure if it's the same on Quadro cards, if the USB drivers are included or a seperate download. Or if an older USB driver will work with a newer graphic driver.

Whenever you do get it working, be sure to tell me the solution. Hopefully it's something that can be resolved without a RMA.

Disregard the bit about the USB driver from Nvidia, it would have to be contained within the monitor, or it would not function with the PS3 via 1.4 HDMI compliance.

Another thing I have noticed, is that when I turn the computer on, the monitor is not connected by default. I have to unplug and plug it in again for it to switch on. :-/
