Thanks, I found a thread here
testube_babies suggest //in fact, it maybe come from netllama
1) In Section "Monitor" of xorg.conf, change the Horizsync and Vertrefresh numbers to a wide range, eg 20-100 for both.
I just added these:
Option "HorizSync" "CRT-0: 50-110; DFP-0: 40-70"
Option "VertRefresh" "CRT-0: 60-120; DFP-0: 60"
2) In Section "Device" insert Option "UseEDIDFreqs" "False" to override the faulty monitor detection. //If I do not add this, the resolution is still ok
It's O.K. now!
