AMD HD 5xxx/6xxx/7xxx GPU behaves differently. Usually you will see an HDMI connector and a DVI connector and/or a DisplayPort connector in the GPU and any of:
- HDMI connector
- DP connector with a passive DP-HDMI adapter
- DVI connector with AMD's proprietary DVI-HDMI adapter
works as a HDMI 1.4a connector that supports Frame Packing 3D video, HD audio and YCbCr color space as well as RGB. However if two displays are connected to the GPU at the same time, then only one connector works as HDMI and the other connector always works as DVI (no Frame Packing 3D video, no audio, only RGB color space). Precisely speaking, if you use HDMI and DP/DVI, then HDMI always works as HDMI and DP/DVI works as DVI; If you use DP and DVI, then DP always works as HDMI and DVI as DVI. In other words, HDMI-likeness decreases in this order:
HDMI > DP > DVI
That means, unlike NVIDIA and Intel, you can't send Frame Pakcing 3D video over one of the connector and HD audio over another (you can still send other 3D formats such as checkerboard, SBS, TAB, interleaved, however). Apparently this is because of a limitation of the HD audio controller of AMD GPU, i.e. non-support for dual audio stream.
