Yesterday my old monitor, a Samsung SyncMaster 152v, suddenly died. So I bought a new one, the LG W2243S-PF. Once I took it out of the box and connected all the cables, I ran sax2 to have my new monitor detected (I didn’t log out from KDE/openSUSE or shutdown my computer). Everything was correctly detected except for the vertical sync frequency (it was set to 50-75 instead of 56-75 Hz). The correct values, as shown in the manual, are the following ones:
Horizontal: 30-83 KHz
Vertical 56-75 Hz
Now I have a much bigger screen resolution. I went from 1024×768 to1920x1080 (21.6″)
