Try uninstalling MSI Afterburner, Display Fusion or Riva Tuner as they are known to cause conflict. Turning off the Windows Night light feature might be required on laptops. Also check to see if firewall rules are preventing the app from starting.

If you have a Rift, make sure you have Oculus Home[www.oculus.com] installed. It is not compatible with previous Oculus runtimes (0.8 or lower)
If you have a WMR headset, make sure to install the Windows Mixed Reality for SteamVR App on Steam.
Check that your headset's USB and HDMI cables are properly connected.

Try turning off the Windows Night light feature, HDR or uninstalling applications that change the color of your screen such as F.Lux. A monitor also has to be detected in Windows so make sure it's turned On.

If you have an Optimus laptop, right-click the desktop and click Nvidia Control Panel, then Manage 3D settings. Set the preferred graphics processor to "High-performance Nvidia processor" globally or specifically for Virtual Desktop (see here[i.imgur.com]).

Microsoft Edge, Internet Explorer and Google Chrome have DRM that prevent those services from being captured. Using Firefox solves this problem.

When using Google Chrome, go to chrome://flags and then search for "touch" without quotes and make sure Enable touch events is set to enabled rather than auto.

Just start your games as you normally would and they should appear in Virtual Desktop. Make sure to disable Desktop Game Theater mode by going in Steam to Settings, In-game and uncheck the "Use Desktop Game theater..." option. If a game crashes or refuses to start while in Virtual Desktop, playing the game in Windowed, Windowed Fullscreen or Borderless mode should solve the issue.

Make sure to turn off Nvidia Shadow Play. It will be enabled by default if you have GeForce experience installed.

Windows requires screens to be associated to a display output on a video card. There's unfortunately no software-only solution to fake a monitor but you can use something like a Headless Ghost[www.headlessghost.com] to emulate one or more.

Virtual Desktop has very low overhead when using DirectX 11.1 features only available on Windows 8 and 10. There are no good low latency APIs on Windows 7 to capture the desktop at a decent framerate so the performance will suffer.

No, Virtual Desktop requires a PC running Windows with an Oculus Rift, HTC Vive or Windows Mixed Reality headset.

Not at this time.
