Product: OMEN by HP 17-cb0900nz
Operating System: Microsoft Windows 10 (64-bit)

I purchased an OMEN 17-cb0900nz from the HP Online Store in December 2019. It worked fine until February 2020.

Now I am unable to select a screen resolution. The selection in the drop-down is greyed out, showing 1920 x 1080, whereby I have a 4K screen and previously I was able to select among many resolutions.

When I try to start the NVIDIA Control Panel, I get pop-up dialog with the message that "NVIDIA display settings are not available. An NVIDIA graphics card was not detected in your system."

I was first alerted to the issue when I was unable to get an external display to work anymore. That is first symptom which caused me to investigate. For completeness The display is a 4K TV connected via HDMI cable to a G2 docking station, connected to the laptop via Thunderbolt. But again, that is just one of the symptoms, the problem is not seeing the NVIDIA graphics chip.

I already tried all of the following:
- Windows update.
- Going back to a restore point.
- Installing video driver for Windows 10 from https://support.hp.com/us-en/drivers/selfservice/omen-by-hp-17-cb0000-laptop-pc/26122176/model/29377...
- Checking the device drivers to see if there are any yellow flags.
- Unplugging cables, powering down, restarting.
