Display Mode Not Supported Error After Plug In New Monitor

Greetings to all,

So this morning I recieved my new LCD monitor...

Plugged in my new LCD monitor to my Red Hat Linux box..

Turn on the machine..

Greeted by the regular OS loader and the interactive startup mode..

Finally it's up and I should see the desktop(KDE) login screen..

..but the screen went black with a "Diplay Mode Not Supported" box floating around..

My guess is because the old monitor's refresh rate/resolution/monitor info... is still being loaded therefore those do not work with my LCD monitor..

Is there a way which I can remedy this little problem I have?

You can press CTRL+ALT+F2 to get to another vt. Then log in as root and edit your /etc/X11/XF86Config. Change the monitor section to have the correct hsync and vsync. Then save and press ALT+F7 to get back to X. Now CTRL+ALT+Backspace to restart X. 8)
