Well we're talking about cables I got a quick question to throw in. Does DP output both analog and digital? In another thread someone stated that they were using just a mini DP to VGA convertor without a signal converter.
DisplayPort is a digital display interface based on packetized data transmission.
To get VGA signals requires an active adapter to convert the protocol and signals to the desired analog output. VGA adapters are powered by the DisplayPort connector.
Can you provide a link to that thread about not having to use a signal converter?
