Unity not redirecting rendering into HMD

Hello all

I am using Unity 2017.4.10f1 and I have an Acer VR headset.

I am trying to just launch my app into the headset from unity
but unity doesn't redirect rendering into the VR headset when I press play.

Any ideas of what could be going wrong?

 

Did you try turning it off and on again?

I'm not joking, I had that exact issue until today when I finally tried rebooting my computer and that fixed it...

This seems to be a pretty common issue though so it might be nice to assemble a list of things to try and double check when this happens.

Another thing that's been mentioned in other threads is that this can happen when you run Unity as administrator.

 

Thank you for your reply.

Yeah I restarted unity and my laptop several times, didn't seem to have any effect.
Also, I don't run Unity as administrator so that shouldn't be a problem

It used to work, and Unity was redirecting rendering automatically into the VR headset, but recently something changed and doesn't work any more.
Not sure, if its related to windows updates.
Nothing I tried seemed to work.

Thank you anyway
