HDMI 1.4a 搞不清楚.

我知道 sandy bridge i3 i5 i7 配 H67 主机板 具備藍光3D的支援能力.
不明白的是 asus,msi,gigabyte 都没有注重 HDMI 1.4a 这个名词.只写HDMI.只有 asrock 表明 HDMI 1.4a.
今天看了 msi h61主机板更加迷惑了,,,只支持 HDMI 1.3.
到底是所有 H67 主机板都是 HDMI 1.4a 还是某些特定的H67主机板罢了.
我在某个网站看到 intel 主机板 DH67BL 是这么写的.
On the back I/O panel we find six USB 2.0, E-SATA, Ethernet, DVI, HDMI 1.4, S/PDIF, five stereo audio and two USB 3.0 connectors. It is worth noting is that with an appropriate DVI-to-HDMI adapter the DVI port can also function as an HDMI 1.4 port, so the DH67BL is capable of utilizing two HDMI cables to provide HDMI 1.4 to a display and HDMI 1.3 to an audio video receiver (AVR) simultaneously for those who wish to enjoy a 3D BD and lossless audio but do not have an HDMI 1.4 compatible AVR.
