Next shot in the dark: Some monitors can be asked to offer their physical data like resolution and such. It is called EDID or something like that. May be the BIOS (or the graka) tries to ask the monitor about its EDID data and the return is "The sound of Silence" ... or something more weird and misunderstandable... And the graka hangs and therefore the BIOS waits forever for the graka and Dale waits forever for monitor... ;) When booted with a "talking and correctly speaking EDID" monitor the garak is setup correctly and everything is fine. If you are using a nvidia-card use the nvidia-settings tool when haveing switched the monitors the "bad way" ;) and in the nvidia settings tool you will find the possibility to "Acquire EDID" (a button). Do this with the new monitor to check whether it talks EDID correctly. Two things I would try to fix the problem: Boot into the BIOS and check, whether "First VGA" (this is how it is called in my BIOS) is set to the correct bus type/card. In my case it has to be set to PCIe. Any may be you will also find a setting to instruct the card to acquire EDID data from the monitor. Toggle this. HTH! Best regards, mcc
