DVI resolution not recognized at boot time (but recognized later)

Asked by Pierre-Alain BOURDIL

With a dell precision 6400M, radeon HD 600 serie, a Eport-plus dock.

I can't boot when i plug my dock with the video 1 dvi output to my DELL ""24 external monitor. The external monitor warns me that the input timing is not correct and ask to set it at 1900*1200@60 (which is the optimal timing). If i boot using the vga port, and then switch to the dvi port , the screen is detected, and i can use it normally (eg: DVI, 1900*1200@60).

For my own it's a bug.
