I purchased a UD-3900H and hooked it up this morning. At first, it worked fine. Then the monitor (a single monitor with HDMI cable) starting intermittently going black. Finally, it went black and stayed black. The light on the monitor stayed blue, indicating that it was detecting signal (it goes orange if disconnected from the cpu). I unhooked the HDMI from the port and hooked it directly to the cpu and the monitor started working again. Please help.
