Of course. If your monitor is unable to produce the proper
vertical/horizontal retrace frequencies necessary to produce high
resolutions, you won't be able to take advantage of the higher
resolutions your card can produce. If you try to push it so that your
card uses the high resolutions, you may need to have a fire
extinguisher handy as it's not unheard of for monitors to be destroyed
this way (the old install guide for Slackware 3.0 actually documents
such an incident)! But as for color depth, if you happen to have
enough video RAM to produce a specific color depth for some
resolution and your card supports it, then there should be no reason why
the higher color depth can't be used. All monitors that have analog
color inputs (i.e. any VGA monitor you can buy off the shelf...the last
monitor with digital color inputs was EGA, and they stopped making
those about nine years ago or so) should be capable of display in true
color if the video hardware that generates the signals is able to.
The maximum resolution you can achieve with 30-50/50-100 (standard
SVGA) should be 1152x900 @ 56 Hz. This is definitely not what you
would call a flicker-free display, so most people would be using
1024x768 @ 60 Hz.
