[quote="mike_ar69"]no it doesn't[/quote] Interesting! Thanks. Perhaps the driver treats our projectors differently. I see in your sig you have an HD66, I have an Acer H5360BD. I also run it through a receiver, which might matter. I think the best advice then for anyone new setting up a screen is to use a ruler to actually measure the separation on the screen and match it to your own IPD, and not worry about what % depth you arrive at. Your physical maximum might be less than 100%, or it might be more (use registry hacks).

[quote="Libertine"]100% used to be too little for me, but they appeared to have increased it in one of the more recent driver releases. Now i use about 75% to 85% depth on my 46" to get my IPD matched.[/quote] I noticed this too. 100% was too little with W1070 @120", now it's way too much.

hi, what I want to add here is,that the IPD is not the limiting factor for the maximum depth . theres a post on german stereoforum.org stating you can/should add 1 cm per m viewing-distance to the screen, which fits my own experience. so lets say 6,5cm IPD and 3 m distance to the screen = maximum far point seperation (which is depth) = about 9,5 cm. regards steps

[quote="stepsbarto"]you can/should add 1 cm per m viewing-distance to the screen[/quote] I wouldn't trust the "should" part of that equation. Our eyes never diverge in real life, normal stereoscopic viewing. I would agree that our eyes "can" tolerate a small degree of divergence. Especially when you sit further back, the angle of divergence is reduced. We can tolerate a small amount of vertical disparity even. I don't have them on hand, but there are studies that support that. I've never heard of depth perception being enhanced by divergence, however. If I'm wrong, I want to know so, but I need scientific evidence. I know this topic has come up a few times before on these forums, the idea that the on screen separation should exceed your IPD depending on screen size and viewing distance. It stikes me as unintuitive, but more than that, it's an idea that I haven't seen supported anywhere else, such as scientific studies of stereoscopic vision, or in professional stereography.

This is why I'm thinking higher depth is more comfortable to view on a large screen from further away.

The bottom line is, divergence is [u]never[/u] natural. Thankfully our brains and vision are a bit flexible so we can tolerate a little divergence or misalignment. However, there's nothing to gain by straining our visual systems. The most accurate and comfortable 3D gaming experience requires a screen with maximum depth calibrated to the viewer's IPD. No more than your IPD, and no less.

[quote="stepsbarto"]What makes me wonder is,when I look on my projector with 6,5 cm max depth it looks a bit squashed and when I increase depth a bit over it it looks natural to me.[/quote] I think this is because everything that's [i]not[/i] at maximum depth gets stretched (enhanced). If you spend most of a game looking at the midground, you can stretch that out to fill the limits of your stereoscopic vision if you push the depth setting. It will look impressive (but stretched, not natural) if you don't try to look at areas of the game at maximum depth. The better solution is to increase convergence. In practice that can be difficult because of 2D HUD elements. But ideally, as you move away from the screen, you should compensate by increasing convergence. [quote="stepsbarto"]But what about the fact that telling the difference of two lines for example 6,5cm and 7cm is easy from 50cm away but difficult from lets say 20m away.[/quote] At 20 meters away, 6.5cm makes little difference. Our stereoscopic vision diminishes in usefulness as distance increases, because our IPD (6.5cm average) makes less and less of a difference. Beyond about 200 meters, our left and right eyes see the same image. Basically, as you move away from the screen, the left and right separation between objects as maximum depth [i]should[/i] appear to be less. If we have a giant 3D Vision screen and sit 200 meters away from it, the correct depth setting would be 0%, because the screen is already at maximum depth. We would just need to crank up the convergence!
