      <pre class="moz-quote-pre" wrap="">forcing DP connector doesn't work well and tests are skipping
with unsupported mode, add new test which runs test on connected
outputs only.

v2: added debug print for better clarity of skips on unsupported mode

v3: added new line in info
    moved skip after test_init
    updated test_init logic based on physical flag
