HMD display is black, but gyro input works???

Recently my HMD has stopped going into display mode when running new builds - the screen stays black, and the indicator light on the top of the display stays yellow, rather than going to the normal blue.

Weird thing is, the HMD gyro works just fine despite the display not clicking on.
I should mention, old builds of the game - a month or so old - DO WORK on the troubled machine - the HMD display clicks on as expected.

This HMD works totally fine in all cases on another machine, so it appears to be a problem with my nvidia-gpu machine (970m on 8.1 & 6.0.1 - same issue on 6.0.0)

Anyone seen an issue like this? The machine in question is our demo machine, so it hurts that this is bugged.

    I'm running into this issue as well.

    Black screen in the DK2 but I can see it working on my monitor.
    The Oculus Demo scene works fine.

    I have a GTX 650 Ti so that should be not be the issue?

    @bakanoodle: You say the demo scene works, so what is it that has the problem?

    I believe 650 ti should be supported. Can you provide these logs? viewtopic.php?f=34&t=23521

    When I press play in Unity the display does not appear in the HMD.
