Samsung Monitor Not Optimum Mode [Causes & Proven Fixes] 

Samsung Monitor Not Optimum Mode

Last night, I was working on my Samsung monitor, and then suddenly, it showed the not optimum mode message on the display.

As I saw the error, I was scared and tried some basic troubleshooting, but nothing worked.

Then I started researching about it and finally found possible solutions to it.

In this article, we will dive into the possible solutions for why your Samsung monitor does not show the optimum mode.

Let’s get started!

Why Does My Samsung Monitor Not Optimum Mode

The “Not Optimum Mode” message on a Samsung monitor typically signifies that the display resolution settings are not configured to the optimal resolution the monitor supports. 

This could be due to several reasons, such as incorrect display settings, outdated graphics drivers, or irregularities in the graphics card. 

It’s essential to adjust your computer’s display settings or update the necessary drivers to rectify this issue and ensure the best visual performance from your Samsung monitor.

1. Disable AV Mode 

If you’re experiencing issues with your monitor displaying a “Not Optimum Mode” message, it could be because the AV mode is enabled. 

To disable AV mode, navigate to the settings menu on your monitor. Look for an option labelled ‘AV Mode’ or similar. 

Select it and then choose the ‘Off’ or ‘Disable’ option. Finding this option may vary depending on the model of your monitor, so please refer to your user manual for specific locations. 

By disabling the AV mode, you will allow your monitor to operate in its default mode, which could resolve the “Not Optimum Mode” issue.

2. Incorrect Display Settings

Incorrect display settings can often lead to issues like sub-optimal mode errors or not optimum mode messages.

This typically happens when the resolution or refresh rate set on your computer is incompatible with your monitor. 

For instance, if your monitor is designed for a maximum resolution of 1920×1080 and a refresh rate of 60Hz, but your computer’s settings exceed these parameters, it could trigger the “Not Optimum Mode” error message. 

Adjusting these settings to match your monitor’s capabilities can usually rectify the problem, ensuring clear and stable display performance.

To adjust the resolution, navigate to Display Settings in your computer’s control panel, select the Samsung monitor, and choose the recommended resolution. 

For the refresh rate, this can be adjusted in the monitor’s menu settings on the monitor itself. 

3. Factory Reset Monitor 

A factory resetting a monitor can be a potential solution when you encounter issues such as the “Not Optimum Mode” error on your monitor.

This process restores the monitor’s settings to their original factory state, potentially resolving any configuration problems. 

To perform a factory reset, navigate to the monitor’s settings menu using the physical buttons on the monitor itself.

Locate the “Reset” option and confirm your choice. Be aware that this will erase any custom settings you have implemented, so be sure to make note of any specific adjustments you wish to reapply after the reset. 

4. Remove & Reattach Display Cable 

A loose display cable connection can also cause the monitor to display an unoptimum mode.

To resolve this, you must remove and reattach the cable. First, power off your computer and monitor. 

Unplug the display cable from the back of your monitor and the graphics port of your computer. 

Inspect the cable for any visible damage. If there’s no damage, plug the cable back into the monitor and computer firmly, ensuring a secure connection. 

Remember to screw the plugs in if your cable has screws. Once done, power on your monitor and computer.
