Monitors have a limit of maximum supported frequency (Refresh rate) for each resolution setting at which display is refreshed. When you set a high resolution with a high frequency that is not supported by the monitor, it displays a message Frequency out of range. Within a few seconds of setting the frequency if you press Esc key it will revert back to the previous resolution.
But what if when you are stuck with the same Frequency out of range and your monitor does not display anything.
Don’t worry, we have the solution if your monitor doesn’t display anything
1. Boot in VGA mode by keep pressing F8 key during boot-up.
2. Un-install the display driver
3. Set the display settings to some supported value
4. Restart, install display (video) driver and set the appropriate settings which your monitor supports.
5. Restart again and it is Fixed.
Tip: Most of old monitors don’t support 1024×768 at a refresh rate greater than 60Hz, so avoid setting this resolution at a frequency higher than 60 Hz if your monitor is an old CRT monitor.
