DISPLAYPORT to DVI converter with male DP (20-pin) connector on one end and female DVI (single link) on the other.
It allows the user to connect a DVI display to a device equipped with a DisplayPort output, avoiding the expense of having to upgrade the monitor for compatibility issues.
This passive converter requires a DP ++ (DisplayPort ++) port, which is what allows the transfer of DVI and HDMI signals in it.
No software or drivers required, a totally plug and play solution
