When the computer screen shrinks and you want to restore full screen, you can try the following methods: 1. Adjust the screen resolution
Screen resolution is a key factor affecting screen display size. If the screen appears to have shrunk, it is likely due to improper resolution settings.
Windows system: 1. Right click on a blank space on the desktop and select "Display Settings" or "Screen Resolution". 2. In the pop-up window, find the "Resolution" option. 3. Choosing a higher resolution usually results in a finer display of screen content and takes up more space. Suggest choosing a resolution with the word 'recommended'. 4. After applying the changes, observe the screen changes until a satisfactory display effect is found.
Mac system: 1. Click on the Apple menu and select "System Preferences". 2. Click on 'Monitor'. 3. In the "Monitor" tab, find the "Resolution" option and select a suitable resolution. 2. Change zoom and layout settings
The Windows system also provides options for zooming and layout, allowing users to adjust the display size of screen content according to their personal needs.
In the "Display Settings" section, find the "Zoom and Layout" section.
Choose a suitable zoom ratio, such as 100%, 125%, or 150%, to change the overall size of the screen content.
After selection, the system will prompt you to log out and log in again for the changes to take effect. 3. Use shortcut keys to adjust screen zoom
Some computers support quick adjustment of screen zoom ratio through shortcut keys, which is particularly useful when browsing web pages or documents.
In the Windows system, you can try using Ctrl++(plus sign) to enlarge the screen and Ctrl+- (minus sign) to shrink the screen.
Note that this adjustment is temporary and only affects the display of the current application or window. It will be restored to its original state after the program is closed. 4. Update graphics card driver program
The graphics card driver is an important factor that affects the screen display effect. If none of the above methods work, you can try updating or rolling back the graphics card driver.
Windows system: 1. Right click on "This Computer" or "Computer" and select "Manage". 2. Find "Display Adapter" in "Device Manager", right-click and select "Update Driver" or "Roll Back Driver". 3. Follow the prompts to complete the update or rollback of the driver program.
Mac system: 1. Click on the Apple menu and select "System Preferences". 2. Click on 'Software Update' to check and update the system and its drivers. 5. Restart the computer
Sometimes, a simple restart of the computer can solve some temporary problems, including abnormal screen display. 6. Check and adjust monitor settings
If the computer is connected to an external monitor and the screen shrinks, you can try adjusting the monitor settings.
Find the adjustment button on the monitor, usually a button labeled with the word "Auto". Press and hold the button for a few seconds, and the monitor will automatically adjust to the best display state. 7. Check the connecting wires
Ensure that the connection cable between the computer and the monitor is securely plugged in and undamaged. If the connecting wire is loose or damaged, it may also cause abnormal screen display.
By using the above methods, most problems with shrinking computer screens can be solved. If the problem persists, it is recommended to contact the computer manufacturer or professional technical support personnel for assistance.
