If you do that often and don't swap monitor too often, you can specify 
the monitor's frequencies in your config file.

Also since you're using some xdm variant, you can just kill the X server 
displaying the login widget at a low resolution with Ctrl+Alt+Backspace, 
once you see it (and thus have your monitor powered on :-) and it will 
restart with correct DDC data.
