Is the monitor plugged into the onboard video or a PDS card? What monitor is it? The LCII onboard video requires one that supports sync-on-green, with specific pins connected (sense pins) that tell the Mac which single resolution the monitor supports. In the early years of Macintosh, all Mac monitors displayed at exactly 72 dots per inch. To do that, each size of monitor was fixed to a single resolution so to get more pixels, you had to get a bigger monitor. When NEC introduced MultiSynch monitors to the PC world, Mac videocard makers soon supported them. Apple went "meh" and stuck with fixed resolution monitors for a while longer. There is a cure for the older Macs. Several companies made various DB15 to HD15 adaptors with either a row of DIP switches or a rotary knob to "trick" the Mac into thinking a fix resolution with sense pins monitor was connected. Only the more expensive ones would make a monitor with seperate synch work with the Macs that require synch-on-green. I think Griffin still makes the best of the monitor adaptors. It can connect almost any multisync monitor to any Mac that doesn't directly support them. Unfortunately Griffin is very proud of their gizmo and wants around $50 for one.
