> In this case, the resolution is wrong and the resolution desired 1920x1080@60 is missing. If you know for a fact the display does have 1920x1080 resolution I suggest you try providing a full video timing mode for that particular resolution. For instace you could try adding to the mode: 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync to the mode entry in for that particular output section. Alternatively, assuming that the EDID supplied by the display is missing that mode, you could also specify one that contains it [1] (note that link is not direct, you'll need to search in the page for edid_firmware). For that, you'll need to generate an EDID yourself. There are tools for doing it, but I don't know any to recommend. Lastly, you could also supply the mode directly in the kernel command line, for the frame buffer configuration [2], and then supply 'mode=current' to pick that one. It might work. Obviously ^ will *only* work if indeed the display actually supports it. Hope this helps, [1] https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html?highlight=edid_firmware [2] https://www.kernel.org/doc/Documentation/fb/modedb.rst > > > > > -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
