What about LCD screens?
Hi, I have a Samsung 19" widescreen LCD 2ms response time, and I cant enable anythingother than anaglyph glasses on the drivers, no matter what driver version I used. The screen is more than capable of displaying the page flipping, and my glasses are polarized in the right way so I see the image on screen. Is there a way toedit registry, do some stuff to force the use of DDC VGA glasses?

The only crazy solution was to boot the computer using a borrowed CRT entering in stereo mode with page flip an then, disconncted it and connected the LCD, and the 3d image was perfect, but what the hell? I cant switch monitors this way every time I want some stereo.

It can be REALLY fustrating to know that your monitor CAN display the pageflipped images perfectly and the drvers dont lt you use it

Thanx a lot

Daniel

Hi Daniel,

...interesting !

You have a really good stereo image with shutterglasses on a LCD ?!?
Even if that means you have to switch monitors ... this would be great ...

Can you describe some more of your settings and image quality ?!?


Regards

The image is very good, the only thing I notice is a little ghosting and it´s probably not related to speed, it´s related to lcd delay, because the is some fractions of miliseconds that the display takes to process the image and send it to the pixels, and this delay, believe it or not exists as a value in the stereo3d section of the registry! but I have no idea on how to tweak it!

I´ve read somewhere like anandtech or xbitlabs about this processing delay, wich has nothing to do with the response time of the pixels.

We really need some driver developer to read this and give us some light.

What I am sure is that with little effort and driver tweaking, nvidia developers CAN bring us some at least very acceptable 3d drivers with LCD mode.

The keys are:

GlassesDelayMinus
GlassesDelayPlus
GlassesSwitchDelay

My config is : Pentium 2140@2.80ghz 2gb ram, geforce 7600gt, audigy2zs and a samsung syncmaster 931bw. drivers 162.50/162.50

Just curious but is there any drawbacks to doing this while a pc is on? Shorts or possible problems later with the monitor port on a motherboard? I'd try this right now but I'm slightly hesitant....

Well, the only thing I can think of is to force the .INF file for your CRT monitor as the .INF of your current monitor.

However, I think this is a bad, bad, bad idea. /geek.gif' class='bbc_emoticon' alt=':geek:' />

I don't know the inner workings of LCD panels, and who knows if the reason they are run slower is to prevent premature burn-out or interstellar vortexes.

What refresh rate and resolution is your CRT running at when you switch monitors?

Also curious.. I have practical experience that lcd's don't work with shutterglasses. Also a fact regarding lcd-beamers. Have just about the same phenomena. Flickering with not really an experienced 3d-effect. Really strange though. With 2ms responsetime there should be a theoretical limit of 500 Hz. But you can't use it even when choosing 60 Hz.

cheers

Hi , Daniel ,

would really like to know more about this ....
.... Refresh Rate,Resolution,Image Quality etc....

I dont know much about LCD technology ,but maybe the CRT
is more in danger ... anyone who knows about that ?

... and I remember with my old ELSA glasses you had to clip a pin
of the vga cable so windows doesnt recognize your monitor anymore to
stop flickering,....could be helpful here ...

aqbout this, I dont know because the vga pastrhough of my glasses does not isolate the monitor from the drivers but it could help, but the delay effect would be still there.

and about this:

I dont think there would be a problem of hotswapping monitors, I´ve done it for various reason for more than 10 years without any problems
