You guys should try running the monitor on the integrated graphics built into the CPU.
Not supported under LINUX any more unless it's an AMD iGPU and AMD cards.
Nvidia disabled the "no-openGL-files" installation option some time back, so their drivers WON'T coexist with AMD drivers or Intel drivers under Linux any more.
Even using AMD iGPU with AMD cards can be an issue, as it sometimes will interfere with clock speed and fan speed control for the discrete cards.
Under Windows, it's trivial - mixing GPUs is one of the very few things Windows handles BETTER than LINUX, and possibly the ONLY thing it handles a LOT better.
