Hardware IPD
The manual IPD dial/wheel on the headset itself and that sets the distance of the lenses so it’s optimal for your IPD.
Software IPD
These settings are found & set in Pimax Play (in Device Settings, under Advanced tab). This sets the image of the left and right eyeballs to be the correct distance. Horizontally & Vertically.
Software Ipd offsets can be customized individually for each eye. The only problem there is no guidance or tutorial on how to set the IPD offsets. In either Pimax Play or SteamVR.
will do this too soon. I’ve got a feeling that it is my right eye which is defective on hardware side but maybe this helps a bit to get rid of the vertical “nebula sections” and blurred barrels I have. I hope it’s not the lense itself…
