Tripp Lite's P134-000-DVI-V2 DisplayPort v1.2 to DVI Adapter Converter allows you to connect a computer with a DisplayPort connection to a DVI monitor. Displayport v1.2 doubles the previous version bandwidth of 8.64 Gbps to 17.28 Gbps in High Bit Rate (HBR2) mode, which allows increased resolutions, higher refresh rates, and greater color depth. Fully molded one piece design ensures longer life. The P134-000-DVI-V2 is a passive adapter and requires that the connected computer has a DP++ (DisplayPort ++) dual-mode port, which allows HDMI and DVI signals to be passed through. Check the documentation for your DisplayPort source for compatibility.
