A customer reports that specific points on their LCD monitor's display constantly show black or the same color even when the screen image changes. These points do not affect the adjacent pixels. What is the BEST course of action to resolve this type of display issue?
Contact the manufacturer for a warranty repair or replacement if the number of dead pixels exceeds the manufacturer's acceptable range.
Check the graphics card settings to see if it's causing the display issue.
Attempt to repair each affected pixel by applying pressure to the screen or using pixel correction software.
Perform a software or driver update for the graphics card or monitor.
