Troubleshooting Msi Monitor: Random Input Switches

There are several reasons why your MSI monitor might be randomly switching inputs. Firstly, check that your monitor is turned on and that the power cable is securely connected to both the monitor and the wall socket. Next, ensure that the display cables are securely connected and that the input settings of the display match the input of your display cable. If you are using an HDMI cable, try switching it to the HDMI OUT port. If you are using a graphics card, ensure that the gold pins are fully inserted into the PCI-E slot and that the video cable is connected to the discrete graphics card. You can also try updating your drivers or BIOS, or lowering your display resolution if it is set higher than what your monitor can handle.

Monitor settings

If your MSI monitor is randomly switching inputs, there are several troubleshooting steps you can take to address the issue.

First, check that your monitor is turned on and that the power cable is securely connected to both the monitor and the wall power socket. Also, ensure that the display cable (HDMI, DisplayPort, VGA, or DVI) is securely connected to the correct input port on your monitor and computer.

If your monitor is connected to multiple devices, such as a PC and a gaming console, the issue may be caused by conflicting input signals. Try turning off or disconnecting one device to see if that resolves the problem.

You can also try adjusting the input settings on your monitor. Press the Input button on your monitor until you find the input that matches your display cable. On some MSI monitors, you may need to access the on-screen display (OSD) menu to change the input. Additionally, make sure that the signal source setting on your monitor is correct. For example, if you manually select a specific signal source, your monitor may not scan other interfaces for input signals after being turned on.

If you're using an NVIDIA graphics card, you can try adjusting the settings in the NVIDIA Control Panel. Check the option that the display port is under and uncheck the other ports.

In some cases, the issue may be caused by outdated or incorrect display drivers or BIOS on your computer. Try updating your graphics drivers or BIOS to the latest version to see if that resolves the problem.

If none of these steps work, you may need to reset your monitor to its factory settings or consult MSI customer support for further assistance.

PC settings

If your MSI monitor is randomly switching inputs, there are several PC settings you can check to try and fix the issue.

Firstly, ensure that the input settings of your display match the input of your display cable. Different display cables require different input signals, so you should check that your monitor is set to the correct input signal. You can do this by pressing the Input button on your monitor until you find the input that matches your display cable.

If your monitor is a secondary screen, you can manage the display settings on your main display to fix the issue. Go to System > Display, then expand the Multiple Monitors and click Detect on the page. If the MSI monitor hasn't been detected, reset and reinstall your graphics drivers and try again.

You should also check that your computer's graphics card is set to a display resolution that your monitor can handle. Find your MSI monitor's model number on the back of your monitor, then look up the maximum resolution in the monitor's user manual. If your PC's resolution is set higher than this, you will need to lower it.

If you are using an Nvidia graphics card, you can try fixing the issue through the Nvidia Control Panel. Check the option that the display port is under and uncheck the others.

If none of these solutions work, you could try updating your drivers or BIOS, or reinstalling your graphics card.

Connection issues

If your MSI monitor randomly switches inputs, it could be due to a connection issue.

Firstly, check that all your cables are plugged in correctly. Check that the power cord is securely inserted into the back of your monitor and the wall power socket. Also, check that your display cable (HDMI, DisplayPort, VGA, or DVI) is securely connected. Examine your power cord and display cable for any obvious damage. If any cables are loose, simply disconnect and reconnect them. If you find any damage on these cables, you should replace them.

If your monitor is connected to a PC, make sure the gold pins of the graphics card are fully inserted into the PCI-E slot. When fully inserted, you should hear a “click” from the PCI-E buckle. If there is dust or foreign matter around the PCI-E slot, clean it before testing the graphics card. Also, ensure that the screws on the baffle are fastened to avoid poor contact with the graphics card.

If you are using multiple devices with your monitor, make sure that the HDMI cable is plugged into the "HDMI OUT" port on your device, not the "IN" slot.

If you are still experiencing issues, try updating your drivers or BIOS.

Resolution issues

If your MSI monitor is randomly switching inputs, it could be due to resolution issues. Here are some troubleshooting steps to address this problem:

• Check the input settings: Ensure that the input settings of your display match the input of your display cable. Different display cables require different input signals. For example, if you're using an HDMI cable, make sure the monitor is set to accept an HDMI input.
• Update your graphics driver: Outdated or corrupt graphics drivers can cause display issues. Visit your graphics card manufacturer's website and download the latest driver for your specific graphics card model.
• Adjust display resolution: If your computer's display resolution is set higher than what your monitor can support, it may cause input switching. Lower the resolution to match the maximum resolution supported by your monitor. You can usually find this information in the monitor's user manual or on the manufacturer's website.
• Check cable connections: Loose or faulty cables can also cause input switching issues. Ensure that all cables, including power cables and display cables (HDMI, DisplayPort, etc.), are securely connected and not damaged.
• Disable "Auto Scan": If your monitor has an "Auto Scan" feature, it may automatically switch inputs when it detects a new signal. Try disabling this feature in your monitor's settings to maintain the selected input.
• Update your BIOS: In some cases, outdated BIOS settings can cause display issues. Check with your computer manufacturer for instructions on updating your BIOS, but back up your data first as there is a risk of data loss.
• Reset your monitor: If none of the above solutions work, try resetting your monitor to its factory default settings. This can usually be done through the monitor's on-screen menu.

If none of these solutions resolve the issue, you may need to contact MSI support or a technical professional for further assistance.
