No HDMI connection, but I have a screen

Hi all,

I got my Oculus rift cv1 and I struggle to get it running.
Everything seems to be okay, except for the HDMI connection.
The Oculus software says that it is not connected, but I have a screen in the headset.
I watched already a VR video and it worked just fine, but neither Steam VR nor the Oculus software works.
It tells me that my Oculus is not ready to to display any VR experiences.
I updated the video drivers to Nvidias 391.35.
Windows detects the Oculus as PnP monitor and I can choose where I want to display the monitor.
I have no other video output, only HDMI. I don't know what else I can do. I have audio and screen.
By the way, the software also reports: "Encountered an error. Please restart your computer or contact.... " I did restart of course several times.
My Graphic card is a GTX950m, which is below the requirements, but I have the screen. Unfortunately I can't lunch any VR stuff except for videos.
It would be great to get some support to make it work.

Looking forward for any idea.

Edit: I run the Diagnostic program and got:
[Service_2018-04-16_21.01.13.txt] 16/04 21:01:13.201 {!ERROR!} [Kernel:Default] Windows 10 system doesn't appear to have RiftDisplay.inf installed. Cannot use DXGI 2 path successfully.

I attached the full log to this post.

I finally managed to install the RiftDisplay.inf
Now my screen is gone and it is black + orange light...

New error log is:

    Laptop mobile graphics can be problematic, especially if you have Optimus. In general, you should prefer using a desktop machine for VR. Not saying for sure that's your issue, but it's likely.

    Hi cybereality,

    I was suspecting something like this. Thinking about to buy a new computer now, however it has to be a notebook.
    A VR ready notebook should be fine I guess?
    What is strange is, that I had screen in the beginning. Now the screen is simply black.
    Anyway, I will check for a new VR ready notebook.

    Ordered the ROG GR8 II from Asus. It is a Oculus Ready PC and should have no trouble to run my Oculus!
    I hope that at least, don't wanna spend 2000$ on something which isn't working after all.
