For the last option:

1. Run the NVIDIA Control Panel
2. Select “Set up multiple displays”
3. Click “My display is not show”
4. Turn off and on again your display
5. Click “Rigorous Display Detection”

 

In many cases, the only option working fine is however to unplug and replug the cable of the missing display :/

I discovered that it was related to nvcuvid.dll by analysing the dump via http://www.osronline.com/page.cfm?name=Analyze

FAULTING_IP:
nvcuvid+dcba9
1062cba9 8b01 mov eax,dword ptr [ecx]

MODULE_NAME: nvcuvid

IMAGE_NAME: nvcuvid.dll

NB.: The dump is available in C:\Users\<Your Account>\AppData\Local\Temp\ while the crash report is displayed (in order to be submitted). It’s deleted once you close the report.

This is a know issue and people post explanations on the web as well as older versions of the dll to be used to fix the problem:

• Nvidia removed the cuda encoding feature from their more recent drivers.
• Open this post (click on the title) to find and download dll’s to be unzipped and copied (with admin rights) in C:\Windows.

NB.: I am running a Windows 10 x64, reason why you can see a SysWOW64 folder in the zip.

NB.: Don’t forget to reboot your PC after copying the dll to be sure those are used (or renamed the old dll before copying the new ones and kill all hidden instances of your converter with the Task Manager).
