Description of problem:
The max. resolution one can select for an Iiyama A702HT VisionMaster
Pro 410 in system-config-display is 1152x864. This is too low. The
monitor can easily handle higher resolutions.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. try to set a resolution higher than 1152x864 for an Iiyama A702HT
Are you sure? When I select the Iiyama A702HT from the monitor list,
I can select resolutions all the way up to 1920x1440. How much video
ram does your video card have?
Graphics card is a GeForce 1 DDR with 32 MB ram.
As root, run /usr/sbin/ddcprobe and attach the results. If ddcprobe
is correctly probing both the card and the monitor, I cannot explain
why you are not seeing the full list of resolutions.
The problem seems to be that ddcprobe only detects 4 MB of ram on the
Created attachment 98186 [details]
output of ddcprobe
Ah, so the configuration tool is trying to limit the resolution list
to something sane for a 4MB card.
I'm changing the component of this bug to kudzu (which does the
hardware probing). However, I'm afraid that the bug may be in the
firmware of the card itself since it is reporting much less memory
than it actually has. If this is the case, then there's not a whole
lot we can do.
Yes, if the card reports a particular memory value, there's not much
we can do other than agree with it. :/
Isn't there some kind of blacklist in kudzu for such devices that have
a broken BIOS?
