Thanks for your reply.

I found the solution - https://forums.lenovo.com/t5/ThinkPad-11e-Windows-E-and-Edge/Thinkpad-E550-External-monitor-flickers-constantly-while/td-p/2046119/page/6 , new VGA firmware is there https://support.lenovo.com/cz/en/documents/HT104459?utm_source=Email&utm_medium=Email&utm_campaign=email%20trace

It's not xorg problem, it's Thinkpad E550 VGA firmware related bug.

Thank you for your time.
