By "adaptors", do you mean logical adapters in motherboard firmware that maybe an update could improve? > Honestly I don't know if there's a way to detect the presence of adapters > like this DP to VGA for instance.

BTW, DP daisy chaining the same motherboard I get the following: Screen 0: minimum 320 x 200, current 4480 x 1200, maximum 8192 x 8192 DP-1 disconnected primary (normal left inverted right x axis y axis) HDMI-1 disconnected (normal left inverted right x axis y axis) HDMI-2 disconnected (normal left inverted right x axis y axis) HDMI-3 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-1-8 connected 2560x1080+0+0 (normal left inverted right x axis y axis) 673mm x 284mm 2560x1080 60.00*+ 1920x1080 60.00 60.00 50.00 59.94 24.00 23.98 1680x1050 59.95 1280x1024 75.02 60.02 1280x800 59.81 1152x864 75.00 1280x720 60.00 50.00 59.94 ...

That logic looks backwards to me. DP-1-8 is the screen in the middle of the cable chain. :-p >> Is there anything with kernel, xrandr, driver, server (or other?) that might be >> changed to better associate the connector names to the actual connector types? >> Is this a motherboard firmware shortcoming?-- "Wisdom is supreme; therefore get wisdom.
