Problem entering Extended Mode on Vive?

[Stanto]

My understanding is that if I go to steam vr -> developer -> disable direct mode, steam VR should restart (which it does) and then the Vive should act as effectively an additional monitor (it doesn't).

What's happening is that Steam VR restarts, and Home still loads. On the vive I am then in a plain white environment and my computer doesn't see it as an extra monitor, so older VR method of games won't work with it (or anything purely side by side).

Is this a bug I should raise or is this expected behaviour?

No. It is the opposite. "Direct mode" secures that your VR headset is NOT an external monitor. It will only play VR content if you activate it.

Yes, you're right, I had the terms mixed up.

I'm actually having trouble entering 'Extended Mode' and disabling 'Direct Mode' doesn't work.
