Can you explain the technical difference betwen CAC-2330 and CAC-1330 HDMI->DP adapters? I am looking at my local dustin dealer, but they don’t seem to carry either of them, so I would like to know the difference before I place any mail order.
I’ve got some extended question to these adapters.
First, I’d wish you used the power from supplied from the displayport side (3.3v 500mA) instead of the awkward extra USB wire. Also I wish they were designed to plug near the DP end, not the HDMI end. Are there any technical reasons for the way it is done?
2nd, will this work between non HDCP compliant devices? I find other brands are not able to do that, because it appeas as if the adapter presents itself as HDCP compatible without even asking the monitor, ending up with no image, even if the source allows non HDCP output. AppleTV is a great source for testing this, as it will send image and allow some apps on non HDCP compliant sinks, and put an error message up on the screen if it needs to. A bad adapter will prevent this.
3rd and last, can the firmware be upgraded from either end? Finding a repeatable device seems to be hard, and it would be nice if they can be upgraded to behave the same way.
