Virtual Desktop for the Quest lets you:
 - Remote desktop into your computer without even launching VR on the PC. You can only view one monitor at the time. 
 - Play videos that are stored on the PC, including 360 and 3D content.
 - Emulate a local HMD and Stream VR games and apps from the PC, be it SteamVR or Oculus, including 

Virtual Desktop for the PC lets you:
 - View and interact ( Remote desktop but... local ) with your desktop in VR, including multiple monitors at the same time. 
 - Play videos that are stored on the PC, including 360 and 3D content.

The PC version existed long before Quest was a thing, but it's literally just a view-your-desktop-and-play-videos program. Emulating a locally-connected VR headsets and streaming that to a remote device, which is what the Quest version does, is a different beast entirely.
You could use Oculus Link to run the PC version of Virtual Desktop, but if you just want to view your desktop and play video files, I would highly recommend just using the Quest version of Virtual Desktop directly. 
With some adb shenanigans it is possible to run VD over usb instead, but it's a bit of a pain and requires some technical know-how
