Hi all, I
would really appreciate your advise, specially from Ilya and esdwa.
I currently own a LCOS LG AF115 Full HD projector and I am satisfied with it in 2D. I am Rainbow Effect sensitive and love the way LCOS show pictures.
For 3D I have an Optoma HD67N 1280x720 which I use for 3D gaming (nVidia 3D vision, VGA connector) and 3D movies (HDMI together with Optoma 3D-XL adaptor). While using VGA connector HD67 shows no lag at all for gaming in 3D and there´s no crosstalk at all (none AT ALL, nothing, zero!, I don´t know if all HD67N are perfect like mine, but mine is perfect with crosstalk, I am also extremely sensitive to this) But picture quality has nothing to do with my other projector, not only for resolution, but for color quality and... blacks are not black :-)
My HD67N lamp life has come to an end, so I was thinking of upgrading to HD33 or HD83. Unfortunately, none of them are nVidia 3D Vision supported, but both are nVidia 3D TV Play supported. I fear this means some lag.
I am a bit lost, I need an advice to decide between HD33 and HD83 considering the big difference in price, for my special case.
It is important to understand that I don´t care about 2D improvement as I will keep my LCOS LG (unless you tell me HD83 is much better, but I think it is not the case). So I am just interested in 3D upgrading. FYI, to consider brightness, my viewing distance is only 2 metres (about 6.6 feet).
I have read, esdwa says about HD33:
"I watch in factory resets with cinema mode and dynamic black and results are stunning comparing to my HD33 (...) I went through around 20 movies last night both in 2D and 3D mode and both looks stunning on hd8300 comparing to hd33, especially in 2D mode. 3D results are similar".
If this is so, there´s no sense for me in investing the difference in money for HD83. HD33 should be enough. ¿Will I really see real dark blacks in 3D? ¿"Black space"? There´s a realy big difference between them in contrast in specifications (at least, on paper) ¿Is your advice to save the difference and get HD33?
But I also read Ilya saying:
"It looks like Top-And-Bottom mode gives shorter lag than SBS for some reason. Not sure though. Just have tried Battlefield2 in 3D Top-And-Bottom (using TriDef driver). Definitelly can't play multiplayer online with that lag." 
Do you, or any other one, know how does HD83 lag compare to HD33 lag? May we expect to be the same? Have you tried PS3 or nVidia 3D TV Play versions or only Tridef? are you using HDMI or VGA connector? Maybe I´ll just forget about upgrading if time lag is so big. I´m used to 3D Vision on VGA and that´s perfect :-(
Thanks for your advice.
Regards!!!
