output to Zalman or 3d-ready DLP's
Posted: Wed Mar 03, 2010 5:55 pm
Hi all,
EDIT: apparently this only works when using a VGA cable and not a DVI cable although this still needs testing for "3d-ready" checkerboard devices. This is for nvidia stereo driver version 162.50 but may or may not work with others.
I wonder if anyone would be interested in this info about how to play in s3d on a Zalman or a "3d-ready" DLP TV or Projector by using nvidia's old-school stereo driver version 162.50? You do not need an E-Dimensional or other dongle for either of these outputs but you do need an IR transmitter and wireless shutterglasses for the checkerboard DLP outputs. Just plug in your transmitter to your display device and switch your display into 3d mode. The Zalman uses polarized glasses.
Set up old-school s3d like you would normally do for DDC shutterglasses and do an nvidia 3d logo test at the 3d display settings you'll be using, then...
for a Zalman:
Native resolution 1280 x 1024 or 1680 x 1050 or other depending on what your hardware accepts. Please post details that work for you if so inclined.
Make a file called h-interlaced-3d.reg with this text in it:
-----
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\Stereo3D]
"StereoViewerType"=dword:00000008
"InterleavePattern0"=dword:00ff00ff
"InterleavePattern1"=dword:00ff00ff
-----
and double-click it to set those settings so that horizontal interlaced mode will work and try your game at the right res. These settings may reset themselves to DDC mode when you open the nvidia display properties window so keep this file handy on your desktop so you can reset the 3d output easily in case that happens. If the 3d mode sends the wrong image to each eye, then change 00ff00ff to ff00ff00 for both InterleavePatterns and that should fix it.
N-joy.

for a 3D-ready DLP TV or Projector:
EDIT: Checkerboard output only!!! I have recently learned that some "3D-ready" DLP projectors take other inputs like frame-sequential or other. This is just for checkerboard output.
Use 60Hz, 1280x720 or 1920x1080 or other depending on what your hardware accepts. Please post details that work for you if so inclined.

"StereoViewerType"=dword:00000008
"InterleavePattern0"=dword:aa55aa55
"InterleavePattern1"=dword:aa55aa55

and double-click it to set those settings so that checkerboard output mode will work and try your game at the right res and freq (60Hz). These settings may reset themselves to DDC mode when you open the nvidia display properties window so keep this file handy on your desktop so you can reset the 3d output easily in case that happens. If the 3d mode sends the wrong image to each eye, then change aa55aa55 to 55aa55aa for both InterleavePatterns and that should fix it.
N-joy.

If you want to understand this and you know hex/binary. Just imagine an 8x8 bitmap formed with each byte of the InterleavePatterns as one row stacked above the next and you will see that the patterns form a mask that is either striped or checkerboard.
I don't need to tell you that this is old driver tech so don't expect it to work with newer games or video cards but if it works fine in normal shutterglass mode, it should work with these outputs too.
That's it.
bye now,

PS: Neil, if you think this info crosses some kind of "hacking" line, just go ahead and delete it. There's no need to even contact me about it. However, I don't see how any company could seriously be threatened by this.
