I have a problem with t480 machine.
I got two identical screens B2289HS from IIYAMA, the issue is when I plug in the usb C one it works, when I plug in the HDMI one the usb c goes off and only works on HDMI
Things I have tried:
New cables, Running usb C to HDMI + hdmi
Different ports for the usb C the one for charging and the one for dock
Lenovo system update, + new bios
switch display priority in bios config to HDMI
Tried changind the lid power options and clocing the lig with 2 screens plugged
Always only one display works at any given time, display setting in windows show only 2 displays at any given time.
Is this some sort of limitation of the intel GPU ?
Any ideas would be much appriciated.
