Graphics Card Issue

Rhino says it’s using my Nvidia GTX1050 card (as do other programs) but the Nvidia Control Panel says my monitor is not connected to an Nvidia device. Has anyone else experienced this?


This is possible these days. Often you can designated a specific GPU to be used as the OpenGL rendering engine, while that GPU isn’t even hooked up to any monitor.

If you don’t want that to happen you’ll have to change the settings for your GPUs.

I do show what Nathan describes, here - the monitors are hooked up to one card but apparently the openGL is pointed at the other - I did not do anything that I know of to make this so, it just is…

Hybrid graphics system.
Primary display: NVIDIA Quadro P4000 (NVidia) Memory: 8GB, Driver date: 7-5-2020 (M-D-Y).

Primary OpenGL: NVIDIA GeForce RTX 2080 SUPER (NVidia) Memory: 8GB, Driver date: 7-5-2020 (M-D-Y). OpenGL Ver: 4.6.0 NVIDIA 451.67


Thanks guys. My driver needed updating in spite of Windows 10 Updates best efforts. It’s always something!
