[19:52] <honepo5385[m]> hello.  Guys, i guess i need some technical help with ubuntu studio 21.10.  Can I ask here about it ?
[19:52] <honepo5385[m]>  all things are nice when i am usng only laptop. but i need to connect external 27' Acer Display. 
[19:52] <honepo5385[m]> When its done, the picture seems blur and just "squeeze" horizontal. Itied to change resolution, update kernel, configure grub and more.  Read about it, but still nothing. 
[19:52] <honepo5385[m]> Im really dont know what i can do next. its soft problem i guess. in kubuntu 20.04 lts and other linux distributions all works fine. Even in Windows 7 too. Well, cmon its only a monitor, i have no ideas about it..
[20:40] <oerheks> honepo5385[m], try reset the monitor itself to factory standards
