Recommended mainboard for ghosting free 3D Vision
  1 / 3    
Till now I have tried two 3D Vision kits on a couple of systems and all of them had severe ghosting on top of the screen . Today I've built a system from some old components laying around and decided to test the 3D vision on it , and to my surprise it has no ghosting whatsoever , the image is perfect . I started a process of elimination and it seems that the only thing that made the difference is the mainboard ( ASUS M3N78 VM) . This has a Nvidia chipset and hybrid-SLI . All the other mainboards that are ghosting are ATI or have Crossfire . I guess there is probably some kind of delay between the signal sent to the monitor through DVI and the USB port on some boards causing the glasses to get out of sync .

I'm looking to buy a DDR3 motherboard , doesn't matter INTEL or AMD , that doesn't cause the ir transmitter to get out of sync and cause top of the screen ghosting . If you have a system that doesn't produce ghosting like the fallowing picture please do tell what type of system you have .

Could you post a pic of the same game or something similar with white vs black all the way up and down the screen on your non-ghosty motherboard? I'm betting if the timing isn't off at the top, it's off at the bottom.

Surely the issue is the display. I get zero ghosting on my DLP projector.

Yes its a display issue. It's to do with the way LCD monitors scan; from bottom to top. Search the forums/you tube for video evidence. This causes the top to become out of sync with the glasses so you get the ghosting. Reminds me of the tracking function with old VCRs.

Lord, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.

I never wondered that this is the ghosting issues cause.

I know how it works , I even posted a slow-mo video on how the image is loaded on a LCD . It doesn't load the whole picture at once , it takes around 50% of the cycle to load the full picture from top to bottom . But still for about 45% of the cycle you will have a full , clear image and the glasses work at 38% so if it's synced you should see just one image . If it's a limitation of the technology then how comes the Samsung and Panasonic 3D theater LCDs don't have top screen ghosting ? It's more like a limitation of Nvidia their lack of tools for syncing . I'm going to experiment with more boards , and if I don't find a DDR3 board that's working , I'll build my own hardware , either a delay for the USB signal or an IR signal emitter with the possibility to adjust the duty cycle .
Here are some pictures taken with the same pair of glasses , same monitor , same processor , same video card the only difference is the mainboard and memory . I think this are enough to prove that there is a out of sync issue probably because some delay on the USB port .

Very interesting!! How are those photos actually taken? Just take the snapshot through one lense of the glasses?

So I guess that, with the right timings, ghosting can vanish. If the timings are off just slightly, you begin to get ghosting starting with the high contrast portions near the top of the monitor.

This is exactly why we should be able to tweak sync timings from 3d Vision control panel. There can always be unexpected latency caused by component x, and it's just matter of some tweaking settings to fix that...
