I recently bought a Wacom Cintiq and installed it as my second monitor. When I start Photoshop CC 64bit, if it opens on my first monitor I am able to use OpenGL features like rotating the canvas or seeing the eye dropper wheel. This continues to work if I drag Photoshop onto my second monitor. However, if PS starts on my second monitor, whenever I try to use the OpenGL features I get error messages saying that OpenGL is disabled for the window.
I would like to be able to open PS on my second monitor and still have all the OpenGL features work.
Nothing to do with PS. That's simply your graphics driver not providing the necessary resources when establishing the OpenGL context. You will have to fiddle with your driver settings.
