@Jessica_hk: Thank for your reply. The ESXi have 2 video cards, 1 for dislay ESXi console (always on and always display the ESXi for configuration), 1 passthrough to a VM (This is on after the VM restart, If VM power off this monitor black out with no signal); in this case, the VM has BIOS, CPU and other resources from ESXi host. I use Vsphere Client (on another PC) to install and control VMs (on ESXi host). When I close Vsphere Client and turn off the PC, everything still run on ESXi and all monitors still display.
But now I do not want to run on ESXi host, but I still need ESXi host runs and "somehow-passthrough" the second video card to my another PC (this PC connect to ESXi host over TCP/IP). In this case, BIOS , CPU and all resources from the PC except the video card from the ESXi host.
I know it sound abnormal, and not avaiable now, but is this possible?
I also think it is possible, because the PC can get the permission to control the PCIe bus (video card) from ESXi, in turn the ESXi pass the PCIe to the PC instead of the VM. But I have no clue how to make it come true.
