Will they ever fix the ghosting on the top screen? It ruins the 3D entirely and causes some minor he
I searched through the forums and I found a post where the majority of the vote said that they have ghosting on the top screen. I also read that the issue isnt related to the monitor hardware because it is the shutter timing on the glasses. A driver would fix this issue but it doesnt seem like its being addressed at all which aggravates me a lot. It ruins 3D movie viewing experience too.. I see a double image on the top 15% of the screen and it gives me a sense of distortion. Moreover it makes it somewhat a nuisance when playing certain games like mass effect.
Can we all rally together and make a voice to be heard to nvidia 3d vision team to come up with a solution for us? I beg you guys, I love 3D so much but the problem makes it a headache playing certain games. /confused.gif' class='bbc_emoticon' alt=':confused:' />

I'm so confused when it comes to the 'ghosting' problem. Some tell me it is a monitor limitation, some say it is the timing on the glasses.. others say buy a DLP TV and enjoy it all ghost free etc.
I do wish for a 3d experience that is perfect, so hard to play a game in 2d after viewing it in 3d :)
If a simple timing tweak on my end is all that is required? hell, sign me up. Give us the option of changing a few advanced settings!

Actually, it's not timing issue from Nvidia, but it *is* monitor issue.

But I am not talking about ordinary ghosting on the screen. That I can live with because its not blatant. I am talking about the fact that the top 15% of the screen has no 3D effect at all. You simply see two images at the top. My mistake for using the term ghosting, I should not have used that word because its not really ghosting now is it. :o

LCD monitor refreshes image from top to bottom and starts doing next eye right after one is finished. So as long as shutter glasses need to be open like 40% of the time per eye you get ghosting. No matter how glasses are synchronized. All you could do by timing is to shift that ghosting area vertically.

This is a driver problem - at least for the Quadro cards doing OpenGL quadbuffered stereo on XP. Using driver version 197.03 and running 100Hz instead of 120Hz, I was able to get perfect stereo on the Acer LCD. Other drivers produced the same effect you are having or even worse.

Well, after little thinking, top-end ghosting could be fixed with future 120Hz monitors easily (however it does increase monitor cost a bit).
Problem is screen is drawn from top to bottom, row at a time.
For 60Hz / 120Hz 2D display, this is fine.
However, for S3D this becomes an issue because there is extremely short time picture is actually 'static' - time between redraws (again, refer to YouTube link: [url="http://www.youtube.com/watch?v=FAQh6bREFqM"]http://www.youtube.com/watch?v=FAQh6bREFqM[/url] ).
What should be changed is add additional memory buffer (if already doesn't exist) and buffer top half of picture as is sent via cable to monitor.
Once half of picture is received, start redrawing picture.
However, instead top to bottom redraw, it should be 2 simultaneous redraws -> top to middle of screen and simultaneously middle to bottom.
This does also require changing LCD panel in a way there needs to be additional electronics on bottom of screen to control bottom half of LCD screen, while upper half controls upper half of screen, thus allowing simultaneous redraw.
What would end result be?
2x faster frame change, which would eliminate currently known 'top' or 'bottom' screen ghosting.
This would *not* reduce other possible ghosting due to LCD technology, but would make it much more better, as the top/bottom ghosting seems to be one which is currently most annoying.
I hope new LCD's to come will introduce something like this.

yip, LCD draws lines like a CRT , whereas with DLP we get still frames , AND , 90% fill factor ^_^ ....such a superior technology....
