Fixing dead pixels
The small free software utility dead pixel fixer can also be used to fix dead pixels by causing them to become unstuck. The utility works by cycling through each of the RGB colors on the screen or portion of the screen, causing pixels that may be stuck on a single color to become unstuck.

LCD or flat panel with dead pixels
LCDs or flat-panel displays can have internal components fail that, in turn, causes dead pixels. Although most users consider this a defect in the hardware, most manufacturers will not replace the monitor unless it has multiple dead pixels. As a general rule, four or more dead pixels that are at least one-inch away from each other.
If your LCD or flat panel is experiencing dead pixels, refer to your manual or contact the display manufacturer to determine how many dead pixels qualifies for a replacement. If the display meets the requirements for replacement, we suggest you have it replaced.
Dead pixels on CRT monitor
A dead pixel is not a common issue for CRT monitors, but may still occur. When it does, most monitors have an entire row or entire column of pixels to go out. Most monitor manufacturers do not have a policy or warranty for this issue and when this occurs will replace the monitor if in warranty.
Contact the monitor manufacturer for information on their policy and how to get the monitor repaired or serviced.
NoteBecause all manufacturers have different policies regarding dead pixels, Computer Hope cannot tell a user for certain whether or not their display meets the requirements to be replaced.
