I've found with some monitors, that unplugging everything, power, and all monitor cables, and leaving it for a few minutes, then plugging it all back in, can sometimes restore the EDID. Some EDID chips stop a copy in RAM that gets powered from both mains and the ddc lines, so you really need to disconnect everything. (though I'm not sure how common this configuration is in monitors).
