Connecting a screen via the HDMI port on the DA200 fails to produce any output with resolutions above 1400x900 (though resolutions less than or equal to this work). The screen is recognized, and low resolutions succeed. This issue is not present when using the same DA200 with Windows, which does display at any resolution. The issue is discussed here as well: <a href="https://bbs.archlinux.org/viewtopic.php?pid=1634085#p1634085">https://bbs.archlinux.org/viewtopic.php?pid=1634085#p1634085</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
