Wondering if anyone else has/had this problem? I have a Lenovo Twist Ultrabook. I believe it is also listed as a Thinkpad S230. It has both a displayport and an HDMI port. I have the displayport connected to a monitor using a DP-HDMI cable, and the HDMI port connected to an older monitor using an HDMI-DVI cable. Either one will work on its own, but when both are connected both screens immediately go black.
I also tried using an HDMI splitter cable on the HDMI port. It works, but the display will only show mirror mode - not extended mode.
When I look in the BIOS for display settings, it gives me 3 options: the local screen, and then to select either of the ports (but not both!) when docked.
Anyone have any ideas?
any feedback or suggestions greatly appreciated!
