If your monitor, smartphone, or TV screen has gone black, frozen, or lost its video output, you can recover the display through structured troubleshooting. First, check all physical connections, ensuring power cords and HDMI or DisplayPort cables are securely plugged in and that the monitor is powered on. Second, on a computer, wake the system from sleep mode by moving the mouse or pressing keyboard keys, or use the Windows Key + Ctrl + Shift + B shortcut to restart the graphics driver. Third, restart the device completely if the system crashed. You can verify success by confirming normal video output and system startup screens appear.
