Sony SDM-S91 Operating Instructions

To adjust the brightness and contrast, use the monitor's menu button to navigate to the 'Picture' settings. From there, you can adjust the brightness and contrast levels using the directional buttons.
Ensure that the monitor is set to its native resolution of 1280x1024 at 60Hz. Check the video cable for any damage and ensure it is securely connected. Adjust the sharpness settings in the monitor menu if needed.
To reset the monitor to factory defaults, access the monitor's menu and navigate to the 'Setup' or 'Settings' option. From there, select 'Factory Reset' and confirm the action.
Check to ensure the power cable is securely connected to both the monitor and a working power outlet. Verify that the power button is pressed. If the issue persists, try using a different power cable.
Turn off the monitor and unplug it. Use a soft, lint-free cloth slightly dampened with water or a screen cleaner. Gently wipe the screen in circular motions to avoid streaks.
Check the color settings in the monitor menu and ensure they are set to default. Verify that the video cable is properly connected and not damaged. If using an adapter, ensure it is functioning correctly.
Position the monitor away from direct light sources or windows. Adjust the tilt and angle of the monitor to minimize reflections. Consider using an anti-glare screen protector if needed.
Ensure the monitor is set to its optimal refresh rate of 60Hz. Check and secure all cable connections. Try connecting the monitor to a different computer to rule out a graphics card issue.
Verify the monitor is powered on and the correct input source is selected in the monitor menu. Check the video cable connection and test with a different cable if possible. Ensure the computer is powered on and not in sleep mode.
Access the monitor's menu and navigate to the 'Power' settings. From there, enable the energy-saving mode option, which will reduce power consumption when the monitor is not actively in use.
