1) I can sent my displaylink device to you by airmail.
1b) I possible I would like to buy two UGA-2K-A devices. (for 2048x1152 use)

2) Hard coding will not be an option for me, to much maintenance, and 
since it will not support my wanted resolutions 1440x900 or 2048x1152 
there seems little point in testing it. (still going to try it)

3) I tried using the normal xorg.conf Display subsection to set the 
resolution, see the previous mail and its attachments, but this did not 
seem to do anything.

4) sysfs interface option would be a fix, but only for advanced users, 
understanding what to do with the EDID is probably not user friendly.

5) what can be don to make the device get the EDID information? the 
intel video controller was able to retrieve it..\

Thanks in advance,

With kind regards,
