However, users sometimes encounter the frustrating “Not Optimum Mode” message, which can disrupt your workflow or gaming experience. This article dives deep into the underlying causes of this issue and provides step-by-step solutions to fix it, ensuring you can effectively use your Samsung monitor without interruption.
Understanding the “Not Optimum Mode” Message
When you see the “Not Optimum Mode” notification, it usually means that the monitor isn’t receiving a signal in a format it can process. This could stem from a variety of issues, including incorrect display settings, incompatible resolutions, or faulty connections. Let’s clarify a few key points regarding this error message:
Why Does This Issue Occur?
The primary reasons behind the “Not Optimum Mode” warning may include:

Understanding these aspects helps in troubleshooting effectively and applying the right fixes.
Step-by-Step Guide to Fixing the “Not Optimum Mode” on Samsung Monitors
If you’re encountering the “Not Optimum Mode” message, follow these step-by-step instructions to resolve the issue.
Step 1: Check the Cable Connections
The first step in resolving the “Not Optimum Mode” warning involves ensuring that all cable connections are secure.
How to Check Your Connections:
- Turn off the Monitor and Computer: Always ensure both devices are powered down before adjusting any cables.
- Inspect the Cables: Check for any visible damage or frays in the HDMI, DisplayPort, or VGA cables.
- Reconnect the Cables: Disconnect and reconnect the cables from both the monitor and the computer to ensure a secure fit.
- Try Different Ports: If available, try a different port on the monitor or a different cable altogether to verify that the port isn’t malfunctioning.
After reconnecting the cables, power on the devices to see if the issue persists.
Step 2: Adjusting Display Resolution
Having the correct resolution set on your computer is crucial for optimal performance. If the resolution exceeds what your Samsung monitor can handle, it will trigger the “Not Optimum Mode” error.
How to Change Display Settings on Windows:
- Right-Click on Desktop: Begin by right-clicking on your desktop screen.
- Select Display Settings: Click on “Display settings” from the context menu.
- Scroll Down: Find the section labeled “Resolution.”

- Apply Changes: Hit “Apply” and check if the monitor responds.
How to Change Display Settings on macOS:
- Open System Preferences: Click on the Apple logo in the top-left corner and select “System Preferences.”
- Select Displays: Click on the “Displays” icon.
- Resolution Settings: Choose “Default for display” or select a resolution that your monitor supports.

Once these changes are applied, restart your computer and check if the “Not Optimum Mode” warning ceases to appear.
Step 3: Update Graphics Drivers

In Safe Mode, the resolution will typically revert to a default setting. If the monitor functions correctly in this mode, consider reverting back to regular mode and then adjusting resolution settings again.
Step 5: Factory Reset the Monitor
If the above steps haven’t resolved the issue, you may want to perform a factory reset on your Samsung monitor. This resets all settings to their original factory defaults.
How to Factory Reset a Samsung Monitor:
- Access the Monitor Menu: Press the Menu button on your monitor.
- Navigate to Settings: Use the arrow keys to scroll to “Settings” or “Setup.”

What does “Not Optimum Mode” mean on my Samsung monitor?
The “Not Optimum Mode” message typically indicates that your monitor is receiving a signal it cannot display. This often occurs when the resolution or refresh rate set on your computer does not match the native settings of the monitor. Each Samsung monitor has specific optimal settings designed to provide the best viewing experience, and deviations from these can trigger the error message.
To resolve this issue, you need to check the resolution and refresh rate settings on your computer. Ensuring that these settings align with the specifications recommended for your monitor can help eliminate the “Not Optimum Mode” message. You can usually find these specifications in the user manual for your monitor or on the manufacturer’s website.
How can I change the resolution on my computer?
Changing the resolution on your computer depends on the operating system you are using. For Windows users, you can right-click on the desktop, select “Display settings,” and then scroll down to find the “Resolution” dropdown menu. From here, you can select your monitor’s recommended resolution, which is often marked as “Recommended.”
For Mac users, go to the Apple menu and select “System Preferences,” then click on “Displays.” You will see the display settings, including resolution options. Select the native resolution that corresponds to your monitor. After making these changes, ensure to restart your computer to see if the error message has been resolved.
What if changing the resolution doesn’t work?
If changing the resolution does not resolve the “Not Optimum Mode” issue, the next step is to check the refresh rate settings. Windows users can adjust this by going back to “Display settings,” clicking on “Advanced display settings,” and then selecting “Display adapter properties.” From there, navigate to the “Monitor” tab where you can change the refresh rate to match the settings of your Samsung monitor.
For Mac users, you can adjust the refresh rate in the same “Displays” menu where you find the resolution options. Make sure the refresh rate is set to what is recommended for your monitor. After making these adjustments, restart your system, and the error should be resolved if it was related to refresh rates.
What cables should I use to connect my Samsung monitor?
Using the correct type of cable is essential to avoid the “Not Optimum Mode” error. Samsung monitors typically have multiple input options such as HDMI, DisplayPort, and VGA. To prevent compatibility issues, it’s recommended to use high-quality cables that match the output ports on your computer and the input ports on your monitor. HDMI and DisplayPort cables are generally preferred for digital connections.
If you are using an old monitor that only has VGA ports, ensure your graphics card can support VGA output. Depending on the cable type, using a converter may be necessary, but it could introduce compatibility issues. Always check to make sure your connections are secure and the cable is undamaged, as a faulty cable can also trigger the error message.
Can a graphics card issue cause the “Not Optimum Mode” error?
Yes, graphics card issues can indeed lead to the “Not Optimum Mode” error on your Samsung monitor. If you recently installed a new graphics card or updated the drivers, there could be a mismatch between the monitor’s needs and the card’s output settings. Outdated or corrupt drivers can also cause display issues. It’s vital to ensure that the graphics card drivers are updated to the latest version compatible with your monitor.
You can check your graphics settings by accessing the graphics control panel specific to your card. Nvidia, AMD, and Intel all have control panels where you can adjust output settings such as resolution and refresh rate. If there are inconsistencies, try rolling back drivers to a more stable version or reinstalling them altogether.
How do I reset my Samsung monitor to factory settings?
Resetting your Samsung monitor to factory settings can help clear any incorrect configurations that might be causing the “Not Optimum Mode” error. To reset the monitor, look for the physical buttons on the monitor, often located on the side or bottom. Navigate to the menu using these buttons and look for “Settings” or “Menu.”
Within the settings menu, search for an option that says “Reset” or “Factory Reset.” Select this option and confirm your choice. After the reset, the monitor will revert to its original settings, and you can reconnect it to your computer to set optimal resolution and refresh rates based on the specifications provided.
Where can I find the native resolution specifications for my Samsung monitor?
The native resolution specifications for your Samsung monitor can be found in multiple places. The easiest method is to consult the user manual that came with your monitor. The manual typically includes detailed specifications, including the recommended resolution and refresh rate. If you have misplaced the manual, it is often available for download on Samsung’s official website by searching for your specific monitor model.
Another option is to visit the product page on the Samsung website. Here, you can find the technical specifications under the “Specifications” section. This information will guide you in adjusting your computer’s display settings correctly to eliminate the “Not Optimum Mode” error.
