Hi,

I have purchased Intel Motherboard 865 and Pentium 4 -
3.0 GHz !!

I installed the softwares and settings on my new PC using my
friend's monitor which is having 17" monitor. The Settings in Display area was set to 1024 * 768 pixels with SUSE Linux OS on his monitor.

But, my monitor is 14", so now it can't run without changing the display settings to 800 * 600. Now, everytime I boot the system using my monitor, the monitor doesn't display anything after the Linux boot process is completed. It just blacks down.

I dont have access to 17" monitor now. Can you please
guide me how to resolve this issue.

Regards,
Steve

The only idea I can contribute is to do a [repair] re-installation of the OS so the changed hardware [14 inch monitor] will be detected and an appropriate driver installed.
I know nothing about Linux.

You should be aware that [during the installation] an Operating System is set up for use with a specific set of hardware. If you change hardware on the OS you need to do it in such a way that the OS will be able to cope with the hardware with which it is presented when it boots.
I think you should have changed to a Standard VGA monitor driver whilst the 17 in was still connected and operating, then shut down and switched.
Then when the system was back up and working [including the display], changed to the OEM driver for the 14 in monitor.

Yep, that's what I had to do when my monitor died, fortunately I still had half a screen, just enough to reset video properties. (Mandrake 9.2) If you can get the 17" monitor that works for a short time, reset the monitor to a generic 800X600 and shut down, then it should work with your 14" monitor. Otherwise a reinstall will probably be necessary.

A lot of other hardware can be swapped, like sound card, modem or NIC, and the hardware wizard (Harddrake in Mandrake) will find and reconfigure during bootup, but the monitor is set in config files for a specific resolution and the monitor used must handle that resolution.

Using something like Knoppix if you have it, it may be possible to either manually edit at least one of the relevant config files, or change it to boot to a console which might at least allow you to run the display setup manually. If either doesn't work you won't have lost a lot of time, and if they do the you don't need to go through a fresh install.

It may even be that it's not the resolution so much as the frequency range that you need to adjust.
