First of all I would like to thank you to enable us to take profit from our HD graphic units!
I am however facing a very anoying problem. As far as I know, the way to enable the quicksync hardware on a z68 motherboard together with a discrete graphic card is either to connect the hdmi output of the motherboard to a display or to use the "detect" button on the resolution control panel (cableless setup). Unfortunately, I my only hdmi display input is in use by the discrete graphic card, so I cannot use the cable method (my display does not have any other digital inputs).
The "detect" method is not working for me. When I click on detect, the control panel only shows an unconnected display of my discrete card (GTX560), but the hd graphics output is missing. I have the newest HD graphic drivers installed (2559) together with the newest nvidia drivers. The HD graphics is enabled both in the motherboard bios and in Windows (I tested it by directly connecting it to my display instead of the graphic cards: in this case, the quicksync acceleration is available, but my discrete card is not used).
Do you have any idea of what am I doing wrong?
