I have a Lenovo Yoga ultrabook which only has a HDMI port. I bought an HDMI to DVI cable, and it works as expected with a LG monitor in my office. As soon as I plug it in the screen is cloned. At home I have an older Dell UltraSharp 2005fp, and for that one it does not work. When I plug the cable in "something" happens, the monitor goes from the "no signal" screen to black. On the laptop however nothing happens. In the Windows 8 display setup I don't have another monitor, clicking "detect" does not find one either. I can manually set a second display for cloning or extending, but never get a picture on the Dell. Connecting my media player thing with the cable to the Dell monitor works for when the player displays it's logo at a low resolution, but when it goes into 750p mode after booting the picture also goes away. Mabye that's due to HDCP though. Any ideas? Something to do with Windows 8, or DVI versions?
