How can I convert my desktop viewer to a virtual reality side-by-side display?

have a custom VR headset whose display just takes HDMI. So I'd like to provide the output of my Windows laptop. However I need the proper screen settings to make 'VR mode' work.

Below I have the code for a see-through desktop that is fully clickable, exactly what I want to send to the device - which is essentially just a 6" HDMI screen. However, I need to get the rectilinear buldge transform thing to really make it look proper on the headset (plus adjust the offset of the sides/'eyes'), e.g.:

How can I go about converting the below code to let me have a proper display for VR goggles like so?

Thanks in advance for any help!
