Hey fellas,
I just got my Displayport -> HDMI cable today and unfortunately I am having connection problems of some sort.
As of now I have 3 displays (DELL U2412M) and my LG TV connected to the card (the TV is connected to my AV Receiver via HDMI, and the aforementioned DP->HDMI cable, goes from the GCard into my AV Receiver). The DELL Displays are connected vial DVI/DVI/DP. The idea was to clone my center Display (primary) to the TV in 1920x1080 as long as I'm running my desktop (non Eyefinity) preset.
First and foremost.... the signal transmission is working, I am getting a picture on the TV but the odd things are:
- Apparently I cannot integrate the TV into my Desktop preset, as soon as I rearranged my DELL Displays after the initial "new display connected - everything is messed up" restart, the TV is only shown as deactivated in the CCC. If I want to turn it back on, he asks me to deactivate another display device for it.
- So far... I haven't seen a new option in Sound Output devices. I installed the AMD driver (from the Fire Pro package) for HDMI playback (reckoning that this was for DP as well) and hoped a new audio device would appear as soon as the system recognizes an adequate counterpart on the far side of the connection (here: my AV Receiver). However, no such device presented itself.
I could use some hints guys, has someone done something like this already perhaps?
Regards
Doc 🙂
UPDATE: Ok since I totally forgot about the differing display resolutions between TV and Displays (1920x1080 vs. 1920x1200) I simply made a hotkeyed profile to turn off all Displays and make the TV primary under the aforementioned resolution. The problem now is, that I am somehow unable to force the TV as only display. I can clone the desktop Display (middle one) to the TV in the appropriate resolution, but as soon as I start a game it deactivates the signal to the TV and runs it on the center screen.
Is there no way to deactivate ALL displays leaving the TV as only possibility for the driver to use?
The sound issue still eludes me. Although the device manager shows the "AMD High Definition Audio Device" it still doesn't show up in the Sound Output devices list. Will try to deinstall the AMD HD Audio devices and reinstall drivers -> worked.... I deinstalled the AMD drivers and simply let the automatic Windows driver thinggie do its thing, now it's just a "High Definition Audio Device", but works as intended as long as the display is active, meaning it shows up in the Audio devices as soon as the Display is being adressed to by the Graphics Card.
