So, this produces again the same 2048x1536 (120.3Khz/75Hz) !?

Kill me if I understand this, would somebody write decent program for
handling resolutions and refresh rates. I am expert in many things, but
please don't ask me to become expert in this. Linux has to grow up !

Pleaaaaseeeee HEEELLLPPPPP.....
