Instructions to get the BEST results from your 3dvision here! A guide for noobs or people that d
Hi all,

I posted this in another thread but think it is worthy of its own, so here are some instructions which will hopefully help anyone unsure of things how to get the best from their 200 bucks...

This guide will help resolve separation and convergence issues (which can cause eye fatigue or a poor-quality 3d experience) to give the best possible fatigue-free 3d results:-

Go to the 'Guides' tab at the top of the page, then 's3d settings guide'. It is a GREAT reference point for newbies and will help both of you resolve your issues.
If in any doubt of the facts regarding refresh rates, convergence / separation settings and the advantages / disadvantages of hardware solutions speak to the guys over on MTBS3d - it is the stereoscopic advocacy group and works closely with stereo 3d hardware manufacturers to get the best results - there are people over there that have been posting daily for years, it is by far the best source on the web for this info.

In terms of 'getting the best 3d feeling', the convergence settings are by FAR the most important aspect, you can get amazing depth of field with very low separation yet the correct convergence, you need the right balance between the 'popout' and 'into' screen effects and your brain fills in the rest. This is exactly why when you hit CTRL-F7 to save settings for a particular game, ONLY the convergence settings are saved. You get this right first, with a suitable separation settings for your eyes (based on how far apart they are), and once this is correct ONLY adjust the separation settings for different users (based on distance between eyes and distance from monitor, monitor size etc).

I spent months whacking up the separation thinking thats what I needed to do, and while it improved the experience a fair bit it really isn't what you should be looking at - once you have your convergence settings correct you will be blown away, trust me! :) A lot of the setup is dependant on the particular game itself (and its 3d coordinate system, which varies completely from game to game - this is why precisely drivers like iz3d's have 'auto convergence settings', which sadly nvidias do not have at this time).

A quick guide on displays.. it is highly recommended NOT to use CRT's as there is noticable flicker (even at higher refresh rates) and also ghosting due to the extreme contrast ratios. The 120hz LCD's shipped with 3dvision are a great solution but you are restricted to a small screen size. If you opt for a DLP TV, don't be fooled by the high screen size and refresh rates - you get checkerboard output (half the resolution per eye), the reason for this is the bandwidth of DVI (HDMI) is not enough to carry a true HD 1920*1080 picture at 120hz. The BEST solution in my opinion is consumer DLP projectors - these give FULL resolution in each eye (though typically you will be restricted to XGA unless you use a DH2G or TH2G to span multiple units), with virtually zero noticable ghosting and a full wall 'holodeck' experience. Make sure you go for the highest lumen output you can, which is important as the brightness is halved in each eye, but this is recifyable by projecting a slightly smaller surface and sitting slightly closer. Ideally we'd all have DepthQ's, but they cost thousands of dollars when there are plenty of perfect stereo-capable projectors on ebay flying around for a few hundred. Also, make sure you know the facts about the new Viewsonic 3d projector about to hit the market for the $1500 mark - this too is checkerboard, meaning you lose half the resolution per eye. If anyone opts to give these units a try, you'll need a custom 3d delay dongle (see my other post for info on where to obtain this) to get the best results - I looked EVERYWHERE for a solution like this and was astounded nothing was available on the open market to fix the simple compatibility issues associated with doing this, so in the end a friend and I took it upon ourselves to do so and I've never looked back.

Hope this helps,

I agree with gold! I'd love to see a list of suggested projectors to use with Nvidia 3D if you could come up with one. Preferably some of those "few hundred" ebay models you referred to. I already have a 22" 2233rz but if I could display 3D on a 10 foot screen I think I would stay in my room forever.

As a long time gamer using CRT TV + Shutterglasses and recently migrated to Samsung DLP HDTV + 3DVision. From personal experience, I didn't suffer any if at all this flicker issue with my CRT while gaming when I run it at 120Hz. It only becomes perceivable to me when I go down to 100Hz.

Regarding DLP and 3DVision resolution, according to TI's white paper, its 3D format is described as quoted below. Personally I agree with the author when he says "...maintains both the vertical and horizontal resolution...produces the highest quality and highest resolution displays available for stereoscopic viewing...". In the end, the checkerboard pattern does give me the best stereo images with a feeling that it's FULL resolution which I attributed to TI smoothpicture algorithm. For me, Samsung LED DLP HDTV + 3DVision is the solution that provides the best bang for the buck presently.

Cheers


Excerpt from TI's paper:
"...
One technical hurdle in achieving cost
effective stereoscopic displays is that
stereoscopic displays require two times
the imaging bandwidth of the standard
2-D displays. For a 1080p television set,
this means that two 1080p input streams
are required. Current solutions to this
hurdle are to either cut the horizontal
resolution by ½ or cut the vertical
resolution by ½. Using these solutions
allows for the transmission of two
images using the currently available
bandwidth but sacrifices either the
horizontal or vertical resolution of the
image. The solution created by Texas
Instruments maintains both the vertical
and the horizontal resolution. This
solution thus produces the highest
quality and highest resolution displays
available for stereoscopic viewing..."
