HTPC computer with AMD kaveri. Cannot get the HDMI working from the motherboard. DVI-D to HDMI is working great, including the sound. Tried WIN 10 -64 with all latest drivers from Asrock (15.20.1060). Also tried WIN 8.1 with latest drivers from Asrock (14.502.1013). BIOS version latest 3.00. Connection is from HTPC/HDMI to Yamaha RX-A1040/HDMI to Konka I-Sport TV/HDMI.
Then with my daughters Lenovo WIN 10 -64 there is no issue at all with HDMI, immediately picture and sound from TV thru amp.
Have also tried several different HDMI cables and different input on TV( 2 HDMI inputs). Can it be EDID/memory or native resolution problem?? Board sent for repair two times and they say it is OK, off course using a different CPU.
