Yes, as mentioned below, I edited /etc/inittab from rescue mode, and changed it to run level 3. And the screen still went black upon reboot.

I have a CentOS 4.3 workstation I use for experimentation on my desk at work.

It was plugged into an old LG 14" monitor, and I switched the video cable to a Samsung 17" LCD without rebooting.

...

The screen resolution was set to 800x600 on the 14" monitor, and the display

worked fine at 800x600 after switching to the Samsung 17". When I changed the resolution to 1024x764, the screen went black and I haven't been able to get it back again.

...

I hoped rebooting and having the system search for new hardware would adjust

the display driver to the correct monitor but it didn't. I booted with CD1 in rescue mode and changed /etc/inittab to start in command line mode (3), but the screen still goes black after going through some initial boot processes.

...

I suspect the issue is driver related, rather than screen resolution related.

When I initially went to change the resolution, it recognized the monitor as a generic VGA, and I changed the monitor type to Samsung Syncmaster 711T at the same time as changing the resolution.

...

How can I get the system to recognize the new monitor?

Did you try booting in runlevel <= 3 and then system-config-display --reconfig? If that works, you could set display as vanilla as you can and then start your customisation over. Also you can peek at several options with system-config-display --help
