Hi jlagana, we strongly advise using a direct connection whenever possible in order to avoid signal problems.
We have a list of tested cables linked below; however, none of them matches the type of cable you are looking for. Still, you can try getting one of those brands or the Agiler AGI-1122 which I saw working with a 27 inch monitor.
Joe_intel, thanks for responding. You didn't answer my primary question re: passive or active, but I think I found the answer in another thread on this forum.
The answer received at the end of that thread in combination with the Wikipedia Displayport documentation has provided an answer to my question.
The NUC D54250WYKH does have a dual-mode displayport according to intel engineers, and the following passage from Wikipedia seems to solidify the idea that a passive adapter should work mini displayport to a single link DVI port:
"The DisplayPort signal is not compatible with DVI or HDMI. However, Dual-Mode DisplayPorts are designed to transmit a single-link DVI or HDMI 1.2/1.4 protocol across the interface through the use of an external passive adapter that selects the desired signal and converts the electrical signaling from LVDS to TMDS. Analog VGA and dual-link DVI require powered active adapters to convert the protocol and signal levels, and do not rely on Dual-Mode. VGA adapters are powered by the DisplayPort connector, while dual-link DVI adapters may rely on an external power source (see compatibility with HDMI, DVI and VGA). "
Anyway, I'm fairly certain that a passive cable or adapter will work. Could you verify that the Mini Displayport is, in fact, dual mode, as stated in the other thread?
It would be great if the Intel engineers would test more of these Mini displayport to DVI adapters and cables for compatibility. There are many perfectly capable DVI monitors in the market place which people aren't ready to replace.
Please be confident the answer provided by Lois H. is the correct one.
If more cables are tested by Intel they will be added to the article linked above.
It may be also possible to update the following document if Intel® NUC owners provide more models to be added to the list. Intel® NUC Boards and Kits — Customer-reported peripherals
