Symptoms
When running a virtual machine on a high refresh rate screen (120/144 Hz), the virtual machine still shows refresh rate to be 60 Hz.
Cause
In reality, the screen refresh rate in the virtual machine is always exactly that of macOS.
But due to certain software limitations, the number shown in the display adapter properties is always 60 Hz and is not an accurate representation of the real refresh rate.
Resolution
Do not refer to the screen refresh rate shown in the virtual machine's display adapter, as this number always shows 60 Hz.
