Question

Hello,

I am trying to install on a machine which is connected on a 21'' Dell Monitor using the VGA input (on monitor).

during installation and when the X Server is trying to start, the monitor screen goes black with the message "Cannot Display this video Mode - Change PC Display input to 1680x1050"

What am i doing wrong? Can anyone help?

Regards.

Answer 1

X is trying to start at a resolution other than 1680x1050. The error doesn't tell you whether centOS is sending a higher or lower resolution to the monitor.

Do you know what modes the monitor will work in? It may support nothing except that one resolution, in which case X will probably not display correctly until you adjust some config files.
