I have tilted my neck...

Here's thought for rotating the PRV:
If you have a second monitor, drag the PRV into it and then set the rotation to portrait. You'd get the rotated PRV but couldn't really use the monitor for much else.
 
Just at thought.

+1, I have an older monitor which has a handy swivel in the mount, and tried the portrait display for kicks using Word, but that did not last very long. The reason is that I am an alt-tab fiend, and also like windows to be poking out from under each other (the main SONAR program is one of the few programs I run maximized, and on the main monitor). For speed of navigation, windows I will shift/resize I float and refocus as needed. As many programs/plugs are scripted to be landscape, a portrait display makes them more difficult to do this with (plus I am too lazy to rotate the monitor back and forth).

I have when walking with my hp-envy x360 laptop tablet...pretty cool...
