Let this be a warning than a review More. Anticipation only briefly: The cable itself makes a good impression and is doing what it should to its specifications.
Now to the problem:
The problem is HDMI 1.4. By Ethernet capacity of the cable is, in my opinion, serious errors in the tablet software to the fore: The tablet automatically and irrevocably elects the Ethernet connection of the HDMI cable as an Internet connection and connects via Wi-Fi, a quasi. Consequently, Internet use is not possible with simultaneous HDMI connection. Unless the monitor or projector is connected to the Internet, which should be the case rarely.
Acer has not yet resolved this issue, I do not know what it is like in other devices. Anyone who wants to keep the same time its Internet connection, can I recommend just one HDMI cable without Ethernet function. Who can do without it / wants or on a projector (are there any at all?) / Television presented with Internet, is in this cable but well cared for.
Edit 19/12/2012:
With the latest Android update Acer has resolved the issue and the cable is functioning properly. After some time of use, I will write more about the cable, until now, it continues to make a good impression and is used almost daily.
