No, I know what crosstalk is, I was saying that bright colors on a dark backdrop are what can cause crosstalk. And the convergence settings are for 3DTV Play, not the projector. DLP does have much less crosstalk than other technologies that use 3D glasses, but in all glasses I've seen there's always at least a little crosstalk (even if only at the edges) when you run them through the stress test of playing games with really deep 3D settings and heavy contrast, but that's what I bought a projector to do.
You're correct about the 3Active glasses though, I did accidentally order the non-144hz version now that I see Amazon has 2 different versions.
Sadly most 3D Bluerays (I own over 30) have such low 3D effect cooked into them that they are very a very poor choice to use to judge the quality of 3D eye wear. Additionally scenes with very high contrast and large differences between the L/R pair may be brief and easily ignored.
I just got a pair of 'TrueDepth 3D' glasses which were marked 'v3.5' on their website and specifically tested/listed to be compatible with the Benq 1070, I compared them to my 3DTV pair's that I had gotten earlier and was disappointed with.
Using my 100" screen driven @ 720P by my Benq 1080ST and Nvidia 3DPlay software I booted up the opening screen of "Skyrim" and then played a bit of "TombRaider2013" and switched my seating and the three pairs of glasses I have looking for ghosting and unblocked red sync on the black and white portions of the displayed images.
- "Skyrim" opening screen: a brightly lit high contrast object floating in 3D space is on the screen with a deep grey background. The 3DTV glasses can't handle this content unless I'm standing directly in front of the screen parallel to it. The left eye has some ghosting which turns much worse as I turn my head (~45D) to look at the edges of the screen. As I turn my head up/down or +/- 45D the red sync signal is easily visible. (then again we already knew that) Both pairs work equally poorly.
Switching to the "True Depth v3.5"s the image is improved and quite a bit better however still not quite perfect. Doing the same 45D view of the L/R edges of the screen will show very slight ghosting and a noticeable reddening of the screen but very minor. The "True Depth v3.5"s win this round.
- "TombRaider2013", I have the depth and convergence set so that the game menu floats 3-5' in front of the screen. The menu is BLACK and WHITE on a grayish background scene of a ocean beach during a storm. Again the 3DTV glasses were pathetic here. With the "True Depth v3.5" glasses on there was slight ghosting and reddish tint at 45D (L-R) head turns (and beyond) but again they performed much better.
To conclude, unlike the "3DTV DLP2 Pro" glasses I'm happy with my purchase of the "True Depth v3.5"s so far. The single envelope sized flyer that came with them was not without some unneeded alarm. The flyer states that the glasses are designed for a "WHITE" sync signal and only list 120hz (not 144hz that the Benq's require). At first I thought they had sent me the wrong model however after testing with both games (TR2013 has some > 4" separation of high contrast elements) these seem to work.
I've yet to decide if I'll pick up another pair of "True Depth v3.5"s for guests or when the ones I use are charging or simply use the 3DTV ones for that or try yet another brand+model out.
