Crosstalk and response time
I get that a better response time means less crosstalk, but why can't we calibrate the timings between the glasses and the monitor to be perfect? As in, have a utility like the 'Setup Stereoscopic 3D' one to setup a delay on the glasses or monitor so they match up exactly right.

The timing is not all that contributes to ghosting. The pixels cannot come up to full brightness and then change completely to dark 120 times per second. Also, the glasses cannot go 100% dark when they shutter. You can still partly see through the side that you are not supposed to. I wonder what each thing does to contribute to overall ghosting. There is the pixel refresh speed, the glasses not going totally dark, and the sync. Everything active ghosts. People claim dlp doesnt, it does, I have the asus vg278h and it is probably the least ghosting setup there is right now.

I've notice the glasses don't completely black out, I suppose that alone means theres pretty much always going to be ghosting. Also is there an explanation for why they black out when you tip them sideways? Been curious about that. I also wonder if the ghosting varies set by set, as in, say between 10 of the same monitor some produce more/less than others.

I can confirm the following dlp projectors have 0% xtalk as proven by Bloodys xtalk test, Acer h5360bd and Benq w710st. White test has no ghosting, black test has no ghosting and its the black test things struggle with ;) I've only had 2 dlps and around 14 3dtv's so i can only speak from experience. I've seen many many tv's fail the black test and some have failed worse than others but the 2 dlp projectors i had had 0% xtalk with 3dvision glasses, cheap chinese import glasses had xtalk and zd201 glasses have zero allso. http://3dvision-blog.com/4056-stereo-3d-display-crosstalk-test-photos-with-some-results/

Wow ... tested my ASUS VG278H with this test. And it sucks as !#&"%"¤ !!!! There's like 30% of normal pic is coming right thru those black and white pictures. If i only had seen that test earlier i wouldn't purchase that shitty device on my table :( ....

So what that it doesn't look so good on the test? It's the best 3d vision monitor around and they all ghost to a certain extent. The test is a worst case scenario, you're never going to see that in games so calm down.

I'll have to try that test out, in my case I have a DLP 3D TV and I've tried a ton of cheap glasses off of eBay, some Xpand DLP Link glasses, and finally my current favs, $25 off of eBay. [url]http://www.ebay.com/itm/Brand-Universal-Active-Shutter-3D-Glasses-for-3D-DLP-LINK-Ready-Projector-/121001808309[/url] The Xpands, older ones, the crosstalk was so severe I wouldn't have even played that way and there was this horrible dark blue tint, fortunately I had already purchased some decent glasses before those so I knew how good it was supposed to be. It's been my experience with my setup that all the crosstalk was due to the glasses I was using and the viewing angle/distance from the screen. When you're sitting too close to the screen and looking at the edges it's effectively like looking at the center of the screen and turning your head. I've only had experience with the an old H3D/CRT setup, My current DLP setup, and the Sony PS3 3D monitor/glasses, which the crosstalk was extreme enough for me to return it even though I only paid $100 for it. It makes me wonder in your cases, like mine with DLP, how much of it may be due to the glasses themselves and not the monitor at all.
