Most video cards for the last 10 years have supported at least a
resolution of 1600x1200. 1280x1024 (considered a 4:3 resolution since the
screens are in that form-factor, even though the resolution is 5:4,
resulting in a mild distortion that most people don't notice) has been a
standard entry-level resolution for about that long.
It's true that widescreens (generally 16:10 (ok, 8:5) for monitors, and
16:9 for HDTV) are a more recent occurance, but here the limitation in
supported aspect ratio is usually in the drivers and not the hardware.
Many new video devices in the last year or two will support DVI-D, and if
so, typically can handle up to 2560x1600 widescreen.
Frying a monitor with incorrect video settings is hard to do these days.
That was more a limitation with older CRTs that didn't do any
sanity-checking on the signal. Modern LCDs connected via DVI won't have an
issue at all, as they're limited by the DVI's bandwidth anyway. Even
connected via analog VGA you're unlikely to cause harm as most monitors
these days will detect an improper signal and just show a blank screen.
And if you send a 4:3 signal to a widecsreen LCD, depending on how it's
configured, you'll either get a 4:3 image in the center of the screen, or
it'll stretch to fill the entire view.
