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: 31.5KHz/60Hz (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 /etc/sysconfig/something, 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). The ___ffff ID seems to be the same thing I saw when installing the beta (quite sure)... 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. Stelian.
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 :( Stelian.
Oops, after reading my own attachement it seems that ddcprobe didn't worked so well :) But I'm sure that this worked 1 second before I send the output to the file to attach. 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... Stelian.
