What does 'Not Optimum Mode' mean?

Last Update Date : Mar 22. 2018



When you see Not Optimum Mode or Video Mode Not Supported on your monitor, it means that you have set your monitor to a screen resolution and refresh rate that it does not support.


What to do?

◾ You should reset the monitor to its optimum resolution and refresh rate.

◾ The optimum refresh rate for all Samsung LCD monitors is 60 Hz, regardless of resolution.

◾ The optimum resolutions for LCD monitors vary by size. The chart below lists the monitors by size and shows their optimum resolutions.
