If you have a spare cable, swapping it out can help determine if the original cable is the source of the issue.

Step 3: Test The Monitor

To evaluate whether your monitor is at fault, connect it to another computer. If the monitor still displays only half of the screen, the issue likely lies within the monitor itself. You may need to consult a professional for repairs or consider purchasing a new monitor.

Step 4: Update Graphics Drivers

Outdated or corrupted graphics drivers can lead to display problems. Follow these steps to update your drivers:

  1. Press the Windows key + X and select “Device Manager.”
  2. Locate “Display adapters” and expand the menu.
  3. Right-click your graphics card and select “Update driver.”

Choose the option to search automatically for updated driver software. Restart your computer after the installation.

Step 5: Check For Software Conflicts

If the issue appears only when running specific programs or applications, the software may be conflicting with your hardware. Uninstall any recent applications one by one to determine if any are causing the problem.

Step 6: System Restart And OS Recovery

Sometimes, a simple system restart can resolve minor glitches. If problems persist, consider performing a system restore to a point before the issue started.
