Cannot get left and right lens in sync- P3Dv4

[OldFlyboy 30]

The calibration of the vertical and horizontal bars is good, lens spacing is good, but in flight (P3D v4) the cockpit Left lens view is higher than the Right lens. As a result everything is slightly askew, two throttles almost touching, ditto  the control yoke, etc.

I adjusted the left and right head straps  so that the upper strap is vertically aligned with the headset but still the same.
Will someone help me get this fixed? Flying is almost perfect but everything is a bit blurred.
Thanks for any help

Check to make sure your video drivers are up to date and also check to make sure p3d is up to date.

I installed the latest NVidia drivers Monday of this week(Nvidia 1060). I'm not sure if P3D v4 is up to date, I installed it last Friday.  Probably a stu..d question but How do I check for updates?

On a side note: Will Flyinside improve things in P3D?

Thanks for your reply HiFlyer.
