Is this the same monitor you posted here?

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.

Yes, that's it! Jeepers, I can't believe that even re-reading the past
LKML posts (even those!) I couldn't find the EDID info and how we had
gotten them. I guess I need stronger glasses.

Wonder why Luca's proposed patch makes the EDID undetectable, now, and
why can't it be retrieved at a later time via i2c. Timeouts too small?

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

Yes, it's the same hardware. I can try the patch, with or without Luca's.
