Well it's not even detected (according to dmesg) and you don't tell me what kind of screen it is. Please describe: - output type (hdmi/dp/..) - please grab xrandr --verbose for this screen from a working machine - please describe which step exactly fails (i.e. failure to detect with xrandr or failure to light up) - please grab a new dmesg from boot-up (yours is cut off) - please exlain when/how you've captured your dmesg while testing (i.e. at which timestamp point have you plugged in the screen and stuff like that).

I tried with latest BIOS (V53), connected the second HDMI port (not the default HDMI port) to Acer HS244HQ. HDMI screen shows nothing yet. But testdisplay -i shows : Connectors: id encoder status type size (mm) modes 40 39 connected eDP 280x160 1 modes: name refresh (Hz) hdisp hss hse htot vdisp vss vse vtot flags type clock [0] 1920x1080 60 1920 1966 1996 2080 1080 1082 1086 1112 0xa 0x48 138780 33 32 connected HDMI-A 520x290 35 modes: name refresh (Hz) hdisp hss hse htot vdisp vss vse vtot flags type clock [0] 1920x1080 60 1920 2008 2052 2200 1080 1084 1089 1125 0x5 0x48 148500 [1] 1920x1080 60 1920 2008 2052 2200 1080 1084 1089 1125 0x5 0x40 148352 .......
