CEA-861 also states that in case the source doesn't transmit the overscan/underscan information, the sink should assume CE formats are overscanned and IT formats underscanned. So it sounds like the display is just following CEA-861 to the letter. Whether that makes any sense for a DP display is another matter. DP spec doesn't mentione anything about overscan. A bit of googling indicated that people are having similar issues with this display on some other operating systems as well. So yeah, sounds like we'd need to add infoframe support for DP so that we could force the sink to use underscan.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
