Red Hat Bugzilla – Bug 14062
Iiyama monitor incorectly probed
Last modified: 2008-05-01 11:37:56 EDT
My Iiyama vision master 403 is incorrectly DDC probed by the installer:
(instead of 27-96 / 50-160 correct values).
What is the 7 character ID for the monitor (it would say something like "DDC
probed monitor IVM1234")
Where can I found this information ? (is there some file to look into, like an
or a program to launch).
Or do I need to go through the whole install process once again?
This defect is considered MUST-FIX for Winston Beta-5

I don't know if this is enough, but running the
WinstonBeta3CD1:/RedHat/instimage/usr/sbin/ddcprobe binary on a RedHat 6.2
system gives me the following (see the attachment).

Is this enough information for you or not ?
Fixed in CVS.
Well, it doesn't seem so...
This time my monitor is under: DDC Probed Monitor -> Unsupported Monitor (31.5
kHz / 60 Hz).
I'm reopening the bug.
ddcprobe didn't get a reply from the monitor, this may be due to a kvm switch, a
loose cable, or the phase of the moon.
Should I try the installer again ?
I'd just install and run the "ddcprobe" command off the CD in
RedHat/instimage/usr/sbin and see what pops out

I suppose you are meaning the usr/sbin/ddcprobe from the iso image
/mnt/cdrom/RedHat/base/stage2.img ? :)
Done, output seems correct to me :(
Oops, after reading my own attachement it seems that ddcprobe didn't worked so
But I'm sure that this worked 1 second before I send the output to the file to
I tried again but each time I get the 'EDID read failed, returned empty data'.
Maybe this works only one time, when the is booted ?
Anyway, seems that your theory on the moon phase is correct...
