would prefer to use a premium cable outfitted as such or a premium after-market cable/connector?
Signal Cable made one for me. Nice.

I run with adaptor from Prtsexpress, no problems

Cobalt Cable
Beware using an adapter on the HDMI end. The DVI is plug is too heavy for the HDMI female to support. You can ruin the connector. This is a very common problem.

Use a cable that is DVI at one end and HDMI at the other.

I use a Verastarr cable for this which was a great improvement over the 'stock' cable I purchased at a so-called 'high-end custom installer'.
