When the display shows' signal out of range ', it usually means that the resolution or refresh rate of the signal input to the display exceeds the range that the display can handle. Here are some steps to solve this problem:
1. Adjust screen resolution: Right click on a blank space on the desktop and select "Display Settings" or "Screen Resolution" (which may vary depending on the operating system). Here, you can see a slider or drop-down menu that allows you to choose different resolution options. Choose a resolution that is compatible with your monitor and suitable for reading. It is usually recommended to choose the "recommended" resolution.
2. Updating or reinstalling graphics card drivers: If adjusting the resolution does not work, it may be due to outdated or damaged graphics card drivers. Visit the official website of the graphics card manufacturer, download and install the latest drivers. Before installation, it is recommended to uninstall the old version driver to avoid conflicts. If you are unsure how to operate, you can use professional driver management software to automatically complete this process.
3. Check monitor settings: Check the menu settings of the monitor to see if there are "auto adjust" or "reset" options. These features can help the monitor re recognize and adapt to the current input signal.
4. Check the connection cables: Ensure that the cables (such as HDMI, VGA, or DP cables) connecting the computer and monitor are secure and undamaged. Loose cables or damaged interfaces can cause abnormal signal transmission, thereby affecting screen display. Try replacing the cable to eliminate this possibility.
5. Change display mode: If your computer is connected to multiple monitors, check the display mode in the display settings, such as expansion mode or copy mode, to see if there are any abnormalities. Try changing the display mode to see if it can solve the problem.
6. Safe mode adjustment: If none of the above steps work, you can try restarting the computer and pressing the F8 key to enter safe mode during the boot process. In safe mode, adjust the screen resolution and refresh rate to lower values, and then restart the computer to see if it can restore normal display.
7. Contact technical support: If the problem persists, it is recommended to contact professional technical support personnel or the customer service department of the monitor manufacturer for assistance.
Be patient and careful during the operation process to avoid more serious problems caused by misoperation. At the same time, if you are not familiar with the operation of computer hardware and software, it is recommended to seek the help of professionals.
