The resolution is listed - look at Mode 1 and Mode 3. It is also providing a preferred Mode. > I might also add, I > have three monitors connected but only one is seen by that command. Check the line above stating "Will scan through until the first EDID is found." For additional monitor EDID's you'll probably have to specify a different I2C bus number. > I'm wondering if there is something wonky with that program.

Adaptors can cause Modelines to not be detected at all or not detected fully. I should count myself lucky because I have not come across such problems at least since using VGA cables with CRT monitors. ;-)
