Out of Frequency Error

[linardni]

My LG monitor shows "Out of Frequency Error" on every booting and goes blank after a few seconds. May I get any precise stepwise instruction of resolving the problem?

Your disply refresh rate is set too high which is not supported by your monito.

(i) Press F8 during boot to invoke the startup menu and select safemode to start with.
