While wrestling with all these other issues, remember that some
displays can't change mode. Ain't physically capable of it. You're more
likely to find them in embedded applications and mobile devices, but they do
occur on desktops and workstations too. For instance, the display I'm
writing this message on does 1280 x 1028 x 8. Nothing else. The monitor
won't even sync if you try 1024 x 768, and the board doesn't have enough
memory bandwidth to do more than 8-bit color at the required 135 MHz
dotclock rate. And that's how it's gonna be until my wife's Mac gets fixed,
and I get my 21" Trinitron back.
So if an application wants a specific mode, it will sometimes have
to be done virtually, not physically.
