Default Re: Unable to set correct resolution for GEFORCE 9400GT in Ubuntu 9.04

1) read out the EDID in Windows (if available)
2) look for matching EDIDs on the web
3) Use tools like the phoenix EDID editor (or similar) to create an EDID

The only option you would need then is

Option "CustomEDID" "string"

where "string" should be replaced with a full path to the file (e.g. "/home/myuser/myedid.bin"

The other way round you want to take a look at the options to disable the EDID or parts of it, and then either modelines or options like the HorizSync and VertRefresh etc.

I am in touch with the manufacturer (Edge10) of the screen, so I have asked if they can send me the correct EDID file. I'll let you know how it works, if and when I get it.
