Hi, Jan, You lightened my way. That's the answer I think. I will try to work it out though you guessed correctly the display device I am unluckily using.
Thanks. - - - TianZJ 在 2016-11-15 18:14:59，"Jan Ciger" <[email protected]> 写道： On Tue, Nov 15, 2016 at 10:40 AM, ZJ Tian <[email protected]> wrote: > Hi, guys, > > I encountered a trouble with passive stereo using quadbuffer. > ^^^^^^^^^^^^^^^^ Duh, I am an idiot, should have read more carefully. If your system uses passive glasses (the non shuttering type) then the problem is most likely in the setup of your display. If the display is using sequential ("active") stereo from the Quadro (that's what I assume since you are using quadbuffer) and converting that to passive, do check for the presence of the synchronization signal. If you aren't using HDMI 1.4 (or newer) connection, you may have to connect an extra mini-DIN or a USB cable somewhere. Some Quadro cards require buying of an extra bracket with a connector for this (like this one: https://www.bhphotovideo.com/c/product/838382-REG/PNY_Technologies_930_50764_0000_000_Full_Height_Bracket_Stereo.html ) If it is this display: http://h20195.www2.hp.com/v2/GetDocument.aspx?docname=c04784690&doctype=quickspecs&doclang=EN_US&searchquery=&cc=us&lc=en Then you may be actually out of luck. The DVI-D and DP 1.2 ports don't support the synchronization signals required, AFAIK. You may want to contact HP support about it and verify with them. J.
