    ## Set up the DisplayPort

    The display subsystem provides the Weston and Wayland compositors, along with `libdrm`, which interact with the DPU driver to render the Wayland client applications. Use the sample test applications to evaluate the basic rendering of the Wayland applications and to connect to the DisplayPort.

    ### Verify the DisplayPort setup

    1. Connect the DisplayPort cable to the eDP0 connector as shown in the following figure:

           <div className="flex flex-col items-center gap-2">
             <img src="https://mintcdn.com/qualcomm-staging/blZpKs_b9On5nj-y/archives/2.1/Technologies/Display/media/qli-display/Lemans_dip_switch_and_rb8.png?fit=max&auto=format&n=blZpKs_b9On5nj-y&q=85&s=97eb5e9b3185286c2e36e5f99bdf605e" alt="Figure: DisplayPort setup" width="550" height="619" data-path="archives/2.1/Technologies/Display/media/qli-display/Lemans_dip_switch_and_rb8.png" />

             <p className="text-sm text-gray-700">**Figure: DisplayPort setup**</p>
           </div>

    2. Power on the device. Weston launches automatically during boot.

    3. Verify the display.

       The following Weston flower pattern displays on both DisplayPort screens, indicating successful setup.

           </div>

    #### Set up multiple DisplayPort displays

    To connect and configure more than one DisplayPort display on the IQ-9075 EVK, use the multiple DisplayPort setup guide.

    <Note>
      For step-by-step instructions, see [Set up multiple DisplayPort displays](https://docs.qualcomm.com/doc/80-80025-18A/topic/setup_multiple_displayports.html).
    </Note>

  <Tab title="DSI setup">
    ## Set up the DSI display

    The display subsystem provides the Weston and Wayland compositors, along with `libdrm`, which interact with the DPU driver to render the Wayland client applications. Use the sample test applications to evaluate the basic rendering of the Wayland applications and to connect to the DSI display.
