Set EyeSeparation and MonitorSize

Hello everyone,

I’m trying to manipulate the stereoscopic 3D settings using the NVAPI.

Is it somehow possible to SET the Eye Separation and the Monitor Size?

For some reason you can only GET the Eye Separation. And Monitor Size can only be changed via a hack in the registry.

Thanks in advance,

Hi Jarod -

There are three public APIs that control separation.


Are these not working or were you not aware of these APIs?

What exactly do you means by monitor size in the context of stereo?
