HOWTO: Use old active shutter on regular LCD monitors!
Posted: Tue Feb 19, 2013 1:33 am
Ok I just discovered this hack that I really wish I would have known 4 years ago, and don't know if anybody knew this.
I found out how to use those old Active Shutter glasses from Razor, eD, and/or x3d, on regular none-3d lcd panels (yes the ones that only do 60hz-72hz refresh), it is most definitely not as good as crt, and the parallax settings are not forgiving but it works! YMMV
Ok, so as some of you may have noticed, if you try to use the old style active shutters on an lcd panel, you will likely see a black screen. This is due to the polarization of the panel from what I have read. But did you know that when you add polorizing filters to already blocked light it cancels out the blocked light and it as if nothing is polarized? So how do we cancel the blackout effect on our active glasses?
<TL DR>
Simply wear a pair of real3d glasses (the kind you get free with your movie theater 3d movies) over your active shutters and you can see the monitor perfectly clear! If I remember correctly these are the of the "circle" polarization type. It cancels out the blackout effect of the shutters, and lets them function almost normally. It does not work well with interlieved mode, but it does work reasonably well with alternating (pageflip?) content. I used Bino to watch Avatar 3d with this. You'll have to play with the left/right swap, and the paralax has to be set to 0 in bino, but it does work!
I also found out by accident that an hp dv9700 laptop screen will work with active shutters(the trick of course is to activate them since it's a laptop screen, but this is accomplished by hooking up the dongle to an external monitor).
Please try this out and let us know your experiences, if you have lcd's that are not 3d but do support higher refresh rates I'd really like to know if this works for you.
