Yes you can. Virtual desktop puts your desktop on a giant virtual screen. Anything shown on your desktop will be shown on your Oculus. Its the most polished vr desktop imo. Lots of screen options and the ability to play most 3d formats also. you can try Bigscreen vr for free witch is almost as good but i find i can get a better picture on virtual desktop.
Virtual Desktop is fantastic, one of my most used apps. Great for watching the football streams on and great for watching films (both porn and non-porn lol) too.
Basically a virtual desktop duplicates the content of your Windows desktop in a VR headset : Anything you can display on your monitor, can be displayed in VR, and in some cases even with 3D effect to boost (even if your monitor is 2D).
