Re: Connecting a DVI monitor to the displayport on a mintbox
Many thanks, gabrielh.
I visited the link and was interested to see in the item description:
'DP2DVIMM6 is a passive adapter cable that requires a DP++ port (DisplayPort++), meaning that DVI and HDMI signals can also be passed through the port.'
So my original question is answered, the MIntBox Pro port IS a DisplayPort ++. Which means that signals for DVI and HDMI are also available on the port's pins. You should mention this in your literature. And call the port a DisplayPort ++ rather than just a DisplayPort.
The wikipedia entry on DisplayPort (
http://en.wikipedia.org/wiki/DisplayPort ) includes this description:
(A) Dual-mode DisplayPort can directly emit single-link HDMI and DVI signals using a simple passive adapter that adjusts for the lower voltages required by DisplayPort. When a dual-mode chipset detects that a DVI or HDMI passive adapter is attached, it switches to DVI/HDMI mode which uses the 4-lane main DisplayPort link and the AUX channel link to transmit 3 TMDS signals, a clock signal and Display Data Channel data/clock. Dual-mode ports are marked with the DP++ logo; most current DisplayPort graphics cards and monitors offer this mode.
A notable limitation is that dual-mode can only transmit single-link DVI/HDMI, as the number of pins in the DisplayPort connector is insufficient for dual-link connections; an active converter is needed for Dual-Link DVI (and analog component video such as VGA, since it employs digital to analog conversion). Active conversion can be powered by +3.3 V wire in the DisplayPort connector, but some active adapters require external power.[24]
VESA foresees that all HDMI and DVI conversion will eventually be handled by active adapters which act as DisplayPort Sink devices, in order to facilitate easier updates to latest HDMI and DisplayPort specs, and work with dual-link HDMI, DisplayPort connections with either fewer than 4 lanes or different data rates, and multiple DisplayPort streams. '
I'll order the adaptor and see how it works with my monitors.
