I've already read this link and many others. GA-Q57M-S2H have q57 chipset and vPro label, intel ME in bios and i5-650 cpu have integrated video.
It is written: "you need a mother board with the Q57 Express Chipset that also supports Intel Integrated Graphics", "you need a CPU from the Intel® Core™ vPro™ processor family . Further, your CPU has to support Intel Integrated Graphics".
But it is not written anywhere that an internal graphics should be used and connected to monitor or external video card may be used and connected to monitor.
Intel's KVM is supported only on integrated Gfx (because it requires some support from the Gfx HW )
