A useful feature of VIOSO is to apply the calibration to the Windows desktop. This allows any program to be run in Windows and displayed on the calibrated screen.
Popular programs run in this mode are for example: Fullscreen custom apps (games, web apps in browser), Media player, CAD programs, Resolume, Powerpoint etc…
Desktop Hooking requires a professional NVIDIA GPU and all outputs arranged into a Mosaic Group.

Setup EDIDs and Nvidia Mosaic (article)
Create a new project with the preset: Desktop Warp:
Only single client and single surface calibrations are supported to be embedded into the Windows Desktop via project mode.
You can setup the different nodes for the project: projectors, surface type, camera..etc
Make sure that the computer node shows a proper splitted Mosaic group. The split should be detected automatically by VIOSO - if not, this might indicate that something isn't properly set up and therefore will lead to issues.
In this preset, there are extra main options to customize:
Overlap type
Select the server node.
Find the “Desktop Warp Parameters” section.
Unchanged: leaves the windows display resolution as is
Explicit: manually choose your own final resolution for the desktop
Auto: will set the resolution automatically based on the overlap calculated by the calibration.
Activate parameter
Click on the node from the layout to expand its parameters
Apply On Startup; automatically activates the calibration on the GPU when VIOSO starts.
Special API parameters: timeout values for the embedding command
Below is an example of a project configuration consisting of 2x projectors combined horizontally in one Nvidia Mosaic.
After you finish the design step, perform the calibration as usual: Guide on the scanning steps
Finally, when the calibration is finished you will unlock the button “Activate” which applies the warping and blending to the GPU.
