Use the sample test applications to evaluate the basic rendering of Wayland applications and to connect to the HDMI display.

If you are experiencing a no-display screen issue on HDMI, see [Debug the HDMI display](troubleshoot-debug-hdmi-qcs6490). After you have set up the HDMI display, run the following test applications to verify the display functionality: Verify composition and rendering of frames on your display. Verify the display driver topology and DPU paths. ## 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.
