I bought a HDMI to DP cable to connect my Raspberry Pi 2 to a screen with Display Port.

HDMI to DP cable

Unfortunately I get no output on the screen.

Is it possible to connect the Raspberry Pi 2 to a screen with display port using this cable? What would I need to configure to achieve this?

Note: I get video output on my TV while using a plain HDMI cable.

    I am pretty sure that this cable actually is a DP-to-HDMI cable not HDMI-to-DP, mind the direction. While there are DP ports able to support HMDI signals (DisplayPort Dual-mode) HDMI does not support DP, so a simple (passive) cable cannout simply reroute some signal lines on different connectors.

That cable is most likely a DisplayPort-to-HDMI cable not a HDMI-to-DisplayPort cable (mind the direction). While there are DP ports able to support HMDI signals (DisplayPort Dual-mode) HDMI does not support DP directly. Since HDMI data transmission is very different from DP there will be no simple (passive) cable that just re-routes some signal lines on the different connectors.


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.

and HDMI@Wikipedia:

DisplayPort ports can be made so that they are compatible with single-link DVI and HDMI 1.4.[200] Compatibility is achieved with DisplayPort Dual-mode ports, which are marked with the ++DP logo, using attached passive adapters.

So while these cables can connect a DP appliance to a HDMI display it's not possible to connect a HDMI appliance (such as the RPi) to a DP display.

You may try to force HDMI output by editing /boot/config.txt
