DLP: Glasses only "sync" at 1920x1080
I am using a 60" Mitsubishi TV with 3D Vision. In the tips & tricks guide it states that resolutions of 1920x1080, 1768x992, or 1280x1024 can be used for a DLP HDTV. Since I only have a GTS-250, I want to cut back the resolution to improve performance. However, if I use any setting other than 1920x1080 I see a double ghosted image through the glasses. It's like the convergence isn't happening. Tried it on a couple games plus the Medusa demo. Same result. I am running x64 Windows 7 with the 1.09 driver.

Thanks for any suggestions you can provide.

There is a hot fix for Mits DLP but also applicable to Sammy DLP. Look in the knowledge base for 3D Vision, it will allow "resize desktop" feature to work in other resolutions.

Hmm I don't think its a resize desktop issue. . .

Hi Duke

Can you explain your problem? What resolution is causing you to see double images?

If I go into any game or the Medusa demo and set the resolution to 1768x992, or 1280x1024 I get the double images. Sort of what the normal 3D vision screen would look like without the glasses - there's no convergence.

Thanks for any suggestion.

Few more questions:

1. Are you using the HDTV resize function in the NVIDIA drivers?
2. Do you have any resize function set on the TV?
3. Does this problem occur at 1920x1080?

1. Yes - otherwise the edges to the desktop are cut off. I have the same issue with resize desktop off too.
2. No.
3. No.

Hi

It sounds like you are experiencing a problem with the HDTV resize desktop. In summary

When information is cut off on the DLP its called overscan mode and is a common mode for DLP televisions set by the HDTV manufacturer. Some televisions have a built in mode called "Reduce" which allows you to view the entire Windows desktop, but this mode is not compatible with stereoscopic 3D gaming.

Essentially you need to use a underscan hot fix we have, found in the KB Article below.
