DVI-D video cable to connect to your DVI digital display. You can even add a adapter to make this a HDMI or DP to DVI cable if needed. If you're still using an older monitor with DVI port, and need to replace the cable, this is for you. The cable is about 6-ft long. These were used in my personal lab for a few years, but I've gotten rid of my old DVI monitors and no longer need these.
