Hi, i hope i post here in the most fitting forum. If not please redirect me.
I have a workstation with two RTXA5000 connected via a NVIDIA Quadro Sync II. With the graphics cards I control 3 Optoma CinemaX D2 projectors (4K 60Hz). I connect each graphics card with a 8k DPI (GPU) to HDMI(Projector) cable. The goal is to view 3D content on the DLP capable projectors with 3D shutter glasses. The glasses are capable with 90Hz/100Hz 120Hz/144Hz. I have the problem that I do not perceive any 3D effect. I suspect that the Hz of the Beamer does not match that of the 3D glasses. I’m having trouble figuring out where (Nvidia Control Panel, Windows11) and what values to set? I am testing with a vtk application from which i know it would yield a 3D effect.
Note: I have tested different resolutions and refresh rates - in this example I use the lowest resolution the projector can manage for 3D to avoid any problems with too low refresh rates.
The 4K projectors are set in Windows (see image) to 1280x720 (3D) and the check mark in W11 for 3D is set. The refresh rate is set to 29.97Hz.
With that alone i do not get a 3D effect (i.e., viewing with the shutter glasses gives no 3D effect). In the vtk application i can see that there is a flickering (left/right image). You can also see that in the second image the Desktop mode hast the desired resolution and refresh rate BUT there is a active signal mode which is 3840x2160, 29,97Hz. The Beamer also displays that its set to 3840x2160, 30Hz.
Thats why i tried setting the parameters through the Nvidia Control Panel. There it gets set to 4kx2k, 1280x720 with 29Hz. If i try to set it here to something different, for example from the tab Ultra HD, HD,SD to 1280x720 on the PC tab with 120Hz it resets itself. Even other refresh rates or resolution just end up in a reset back to 4kx2k, 1280x720 with 29Hz. The projectors state for PC-3D-Timing that they can use 1920x1080 with 120Hz. I also checked the global 3D settings in the Nvidia Control Panel. Here i set stereo to ON and selected generic active stereo but i also tried Displayport In-Band Stereo. Do i need a different/additional setting?
What settings should i set and where should i set them. In Windows or only in Nvidia or somewhere else? And is there a tutorial to connect multiple projectors via one/two graphics cards which could help me here?
