In your dxdiag file, the DDI and DirectX feature levels, among other things, are listed as 'Unknown', and the DisplayAnalysis results don't list any display modes (supported resolutions and refresh rates), except one that is obviously invalid.
Check for updated drivers, for both GPUs, as well as Windows updates (especially anything DirectX related).
Try a clean re-install of the nvidia graphics drivers. See
here or
here, for example.
Check your laptop manufacturer's support site, to see if there are any driver or inf file updates for the display.
Try checking your system files:
- click Start, type cmd into the search box, right click Command Prompt and select run as administrator.
- type the following command and hit Enter
sfc /scannow
When that is done, type exit and hit Enter, then reboot your computer.
