-When passing through a GPU (be it a full device, or a vGPU), if you want to use
-it for displaying, you have to either physically connect a monitor to the
-card (if possible), or configure a remote desktop software (e.g., VNC, RDP)
-inside the guest and use that.
+It is not possible to display the frame buffer of the GPU via NoVNC or SPICE on
+the {pve} web interface.
