Bob, i suppose i understood why it happening. I have ASUS VC60 with Intel 4000 graphic card with HDMI only. When monitor is disconnected i can use RDP (Windows Remote Desktop) only. Teamviewer and another remote control programs don't work. I see black window only. I found solution in the Internet how solve this issue. Need to use HDMI Dummy Plug (like that). I'm going to purchase and test again. I will keep you touch.

P.S. RDP is Windows Remote Desktop. =)
