Is there anyone to help me out from this problem. I exchanged the monitors of the system which had Linux OS in my office. Previous one was TFT monitor and I changed it with LCD. But now Linux is not loading and a message like "out of range" message pops up. I know that it could be the reason with the graphics that had configured while installing the OS before for that monitor. I was using "Red Hat Enterprise linux 5" Server edition 32-bit X86. So to solve this issue is there any need for re installation of Linux. Please help me from this.
