This, however, is not the monitor's native resolution and gives me an image quite stretched vertiy, which I find unacceptable. Does anyone know of a way to specify the use of a different EDID (other than lines in - which didn't seem to work) ?

I then read on Samsung's tech support website, and other posts, that single-link DVI cable won't allow me past this resolution because of bandwidth limitations, so I hooked up an analog cable, which got me to a maximum resolution of 1920x1080. It is a shame that Samsung does not make its firmware available as I could just as easily update it myself using the USB port at the back of the monitor and using the software update option in the monitor menu.
