Hi.
For static 360 images we use Google VR View for the Web:
https://developers.google.com/vr/ --> (https://developers.google.com/vr/concepts/vrview)
Easy implementation into html, although has no options to customize the view.
But its free!
Hi.
There's a quicker solution:
WindowsKey+Shift+LeftKey (or WindowsKey+Shift+RightKey) moves the active window (has focus) to the other monitor. Works also with child windows, like the render setup.
For me is the most used keyboard combination with my dual monitor Setup
Hi !
You don't mention the output resolution, render settings nor the renderer (vRay, Mental Ray, Corona, etc).
In any case, the image has a lot of objects with reflections/refractions, so i think that 30 mins it's not too long...
