It looks like the TMDS mode checks for available modelines. For 1600x1200 it
cannot find any, so it starts using the modelines you provided. In the 2nd
try it _does_ find a working mode in its BIOS, so it doesn't look any further
at your configuration. From what I gathered about TMDS, it's an automatic
setup for XFree86:
You might want to give the 1680x1050 setup another try after turning TMDSCoherentMode to off. I'm interested to hear what your results will be.
I must say. I to thought it might be that some time ago. But because It worked at the other mode I never gave it another thought. Sadly I tried what you said and still got no result :-(
Here is the log with it turned off

Any other ideas would be wonderful. I'm willing to try just about anything.
