I recently bought a replacement screen for my laptop, after it's been cracked for over 6 months. When I go to NVIDIA control panel the "stereoscopic" option does not show. Yes it's being read as 120hz, and I verified the part # and it is HD-3D. Here comes the kicker, when I plug in a external monitor such as my TV threw HDMI or CRT monitor threw VGA (both devices only being 60hz refresh rate) and set them as primary, the option of stereoscopic shows up!
My guess it's something internally, perhaps its something loose or damaged, but what can effect the computer for not detecting the screen as 3D ready. So I'm looking for ideas or similar problems so we can track this and help us all out together for the past, present, and future people who run into this situation.
Things I've tried:
1) I installed the old cracked screen that I played 3D on numerous of times and it did the same thing with it as well
2) reinstalled different versions of NVIDIA drivers in safe mode, didn't work
3) Run stereoscopic setup menu while 60hz was set as primary, disconnect it and setup automatically shut down
4) Run stereoscopic setup menu while 60hz was set as primary, connect ir emitter, then upon choosing glasses, only discovery (red,blue) showed and 3D display not found.
5) Reinstalled windows 7, 2 times, and did a fresh install of all drivers.
One thing I've learned, whenever I did the fresh install of windows and installed the original Physx and graphics from ASUS website, the 3D button worked on the laptop shortcut key, but after updating to the newer NVIDIA driver, it stopped working. Obviously that may have nothing to do with the screen but I see some people ask about that problem, so threw my efforts I hope that may help you other individuals out.
