Is this the same monitor you posted here? http://marc.theaimsgroup.com/?l=linux-kernel&m=112807065616218&w=2 If yes, we already have the manufacturer and model code. The main problem is that the EDID of this display has no sync range (H: 75-75kHz and V: 60-60Hz). Extending Hsync from 30-75kHz as a fix to the EDID block shouldn't be too hard. I already have a patch for this which I forgot to send to you before :-). If you can confirm that this is still the same hardware, I'll send you a test patch Tony From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Antonino A.
