These are essential parameters to keep signal quality as high level as possible between the sink and the source. Failing to due so, will lead corrupted image in form of frame losses or in worst case scenario no image at all. #assessment</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
