There is a whole thread about the problems of the Intel Apollo Lake platform and others with quite a similar board (J4205-ITX) report they also updated their hdmi firmware. <a href="https://forum.kodi.tv/showthread.php?tid=270298&pid=2553256#pid2553256">https://forum.kodi.tv/showthread.php?tid=270298&pid=2553256#pid2553256</a> The Apollo Lake boards use a "HDMI-2.0-LSPCon MegaChips MCDP2800", there is a similar chip on my board so I'm pretty sure it is an internal DP port mapped to the HDMI port. <a href="http://www.megachips.com/products/displayport/MCDP28x0">http://www.megachips.com/products/displayport/MCDP28x0</a> <a href="https://www.heise.de/imgs/18/2/2/5/8/6/6/2/MegaChips-MCDP2800-903a5c8eddf6bffc-b4c059ea0025935c.jpeg">https://www.heise.de/imgs/18/2/2/5/8/6/6/2/MegaChips-MCDP2800-903a5c8eddf6bffc-b4c059ea0025935c.jpeg</a> <a href="https://www.heise.de/newsticker/meldung/Intel-Celeron-Gemini-Lake-mit-HDMI-2-0-und-SGX-3801532.html">https://www.heise.de/newsticker/meldung/Intel-Celeron-Gemini-Lake-mit-HDMI-2-0-und-SGX-3801532.html</a> I have a second TV of the same model and it's connected to my main HTPC with an i3-6100 & GA-B150N Phoenix-WIFI board. This combination works quite fine, also the logging of those messages started with kernel 4.15 so I guess it's related to recent patches. So all in all I'm pretty sure it's using the same lspcon & I didn't use the wrong system to gather information.</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>
