Section 11: Display Testing and Adjustment
This section provides procedures on how to perform some final tests and adjustments on the billboard
and billboard components to verify they are functioning and adjusted properly.
11.1 Diagnostics Checks
After the display is connected to the Internet and running, Daktronics NOC will monitor the
display and perform some checks to determine if there are any:
• Module issues
• Internet or connectivity issues
• Webcam issues
• Display temperature issues
• MDLS issues
11.2 Display Image Quality
After the display is showing content, visually inspect the display for:
• Inaccurate or off color
• Module edges
• The display is too dim or bright
• Modules out
• Abnormal flashing
• Modules stuck on
• Pixels stuck on or bright
Work with Daktronics NOC to address any visual issues.
11.3 Test the Light Sensor
Contact Daktronics NOC and perform these steps to verify the MDLS in functioning properly. To
test the photocell:
1. Carefully cover the MDLS with a heavy piece of cloth.
2. Watch the display for a few minutes to verify the display dims.
3. Have a NOC technician monitor IDM at the same time to verify the display is dimming
properly.
4. Work closely with the NOC technician to correct any issues.
5. Remove the fabric from the MDLS.
