Hello fellow Stereo3D persons,

My name is Ross Baker, I am just starting off getting into Stereo3D. I had purchased a pair of EDimensional wired shutterglasses a while back, for use with my Radeon 9800. Rather disappointed, I put stereo on the back burner. Now, having recently upgraded to an Nvidia 7800GS video card, I've loaded the newest Beta NVidia stereo drivers, and am in awe with the quality of the stereo.

However, the big thing bugging me is the ghosting... I know it's been gone over a million times already, but it is annoying as heck, especially in dark games like CoD, Doom2, etc. I've tried playing with different refresh rates, resolutions, contrast/brightness settings, etc. The only things which really worked for me is increasing the stereo seperation (thus the ghosts are far away from eachother, becoming less noticable) and washing the screen out with high brightness/low contrast (because a white ghost is less visible on a gray background than on a black background.) (However, now the whole thing looks like poo as Its all gray and bland.)

I am using an NEC FP2141 CRT monitor... which was very expensive (and as I heard in many a review) very good. Specs: 22" (20" viewable) 390mhz pixel clock, refresh rate @ 1024x768 = 50-160hz. Plenty of beef there. However, ghosting is still VERY apparant during gaming. I would like to know if for some reason my monitor has more ghosting than others. Is there a ghosting test I can run? Anybody else using a similar monitor? Is it too big maybe? (I don't see many reviews with anything over 19") I just want to be sure a cheap little monitor wouldnt be able to outperform my huge, expensive monitor.

I've heard also that the shutterglasses themselves cause ghosting, as they do not completely block the light coming from the monitor, thus no matter how good the monitor is, eye A can still see a little bit of whatever eye B is only supposed to see.

Is there a way to turn on the shutter glasses so both eyes are blocked, as a test to see how much blockage they have? I remember when using E-D's drivers with my ATI, every once in a while they'd lock up with one side blocked... but I cant remember how dark they truly were. It'd be an interesting find! (Though on Stereo3D's review of the DepthQ projector: "LCD-panels manufactured by i/O-Display/Ilixco which are distributed under such brands as eDimensional, X3D, ELSA, H3D, i-glasses seem to give the best results." - meaning mine are really good)

I also ran into something interesting while playing around... Using the Ctrl-F11 "Cycle Fustrum" command, there is a mode which clears the left or right edges of each eye view... leaving a band of "black" on one side for one eye, and the same band on the other side for the other eye. By closing one eye, I can still slightly see what is meant for the other eye... which should be completely black. Does this point to any answers?

Or, should I suck it up, keep playing, and the ghosts will vanish as I get used to them?

Hey, thanks a million for all of your help!
