LCD monitors are usually less picky about displaying analog signals (using VGA video card output) than they are displaying digitial signals (using the digital part of a DVI card output). VGA (analog) almost always displays whereas DVI (digital) sometimes doesn't. That doesn't prove it's the monitor. The video card's digital output could be putting out a digital signal that the monitor won't display.

Did you try booting in VGA mode using the digital input on the monitor? VGA mode is another entry in the same list with safe mode. Seeing which resolutions work might help figure out whether it's the monitor or video card. (Borrowing someone else's monitor would come in handy here, of course).
