Im trying to connect to my second monitor to my PC using a hdmi to Cat6 extender. The solution consists of a transmitter and receiver unit, which are connected together with a Cat6 cable. Each end is then connected to the PC and TV with a hdmi cable. The plan is to have this screen in a different room than my PC.
When connecting everything, my OS picks up the screen as a 3D monitor. However, the screen remains in standby mode even tho it is visible in the display manager. It is almost like the OS sees the device, are unable to communicate with it.
Both hdmi cables have been tested and found to work. The cat6 cable has been swapped out with a known working cable. Changing the resolution / refresh rate resulted in no improvement.
I am on ArchLinux with Gnome display manager but have tried it also on a Windows 7 laptop with the same unsuccessful result. Here are some info from xrandr:
