Rhino 5 running on the external monitors is extremely slow and clunky. The NVIDIA card is not being detected, instead running on GDI Generic.
The Nvidia control panel is set to run Rhino on the GPU, and this works when it is opened from the laptop screen, as long as the laptop is set as main display. Whenever opened from the external monitor as a main display, it reverts to GDI Generic, which is unusable.
I know the Nvidia GPU is functional on the external monitor as the main display, it works no problem with Navisworks and DWG Trueview. It also works for Rhino if the program is opened with the laptop as the main display, and then dragged over to an external screen. This is my current work around which is a pain.
