          Priority: medium
            Bug ID: 72648
          Assignee: dri-devel@lists.freedesktop.org
           Summary: All 3 monitor EDIDs show the same
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: jim.cromie@gmail.com
          Hardware: Other
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

I recently bought a 3rd monitor, plugged it to my radeon,
turns out its EDID is bad; it caused 2 of 3 monitors
to go to low-res, which Id reboot to correct (ick)

I fixed that with 
   drm_kms_helper.edid_firmware=VGA-1:edid/1920x1080.bin

.. which is nice, esp as its been available since 2012 :-)


what worries me is the following:
I have 3 different monitors on the 3 video connectors,
and dmesg (pasted below) confirms this.

      <p>
        <div>
        <pre>I recently bought a 3rd monitor, plugged it to my radeon,
turns out its EDID is bad; it caused 2 of 3 monitors
to go to low-res, which Id reboot to correct (ick)

I fixed that with 
   drm_kms_helper.edid_firmware=VGA-1:edid/1920x1080.bin

.. which is nice, esp as its been available since 2012 :-)


what worries me is the following:
I have 3 different monitors on the 3 video connectors,
and dmesg (pasted below) confirms this.
