Since the EDIDs are not read out in your configuration, Xorg doesn't know
the exact timing for the U3011 and just creates an ModeLine from the
hsync/vsync values you provided. So I guess you would need to add a
ModeLine for the U3011. Second, Xorg doesn't know which device is connected
where, so it might be worth a try to swap cables or swap the order in
However, since you are using the default 3840x1024 resolution for the
TH2G, it may not be necessary to supply a modeline and to disable
the use of the EDID: let Xorg probe the connected devices and it
should just work.
For future postings on this topic, I suggest to add the nvidia-bug-report.log
in order to get more insights from the Xorg.0.log.
