DEAD PIXEL TEST

Stuck Pixel Fix Tool

Free online tool to repair stuck pixels. Rapid color flashing may revive stuck sub-pixels. No download required.

Important

  • Only works for stuck pixels (colored dots) — not dead pixels (black dots)
  • Run for 10-30 minutes per session
  • Success rate: 30-60% — not guaranteed
  • OLED screens: Limit to 10 min max to avoid burn-in

Flashing repair box will appear on your screen

How It Works

Step 1: Confirm Stuck Pixel

Use our Stuck Pixel Test to verify the pixel is stuck (shows a fixed color like red, green, or blue) rather than dead (black).

Step 2: Position Repair Box

Click "Start Repair" to enter fullscreen. Move the flashing box over the stuck pixel location on your screen.

Step 3: Run Repair Session

Let the rapid color flashing run for 10-30 minutes. The fast RGB cycling sends electrical signals that may unstick the pixel.

Step 4: Test Results

Exit and test the pixel again. If still stuck, try another session or consider pressure method.

Stuck Pixel Fix Success Rate Analysis

Based on aggregated user reports and manufacturer data, here's what you can realistically expect when attempting to fix stuck pixels.

Success Rate by Pixel Color

Red Stuck Pixel45-60%
Green Stuck Pixel40-55%
Blue Stuck Pixel35-50%
White Stuck Pixel30-45%

Success Rate by Fix Duration

10-20 minutes45% success
20-40 minutes55% success
40-60 minutes60% success
60+ minutes65% success

Diminishing returns after 60 minutes

Factors That Affect Success Rate

Higher Success If:

  • • Pixel recently stuck (less than 1 week)
  • • Single-color stuck (not white)
  • • New monitor (under 1 year old)
  • • Caused by static charge
  • • Combined software + pressure method

Lower Success If:

  • • Pixel stuck for months
  • • White stuck pixel (all sub-pixels)
  • • Older monitor (3+ years)
  • • Physical damage caused the stuck pixel
  • • Manufacturing transistor defect

Recurrence Warning

Even if the fix works, approximately 20-30% of repaired pixels will re-stick within 1-3 months. If this happens, you can try the fix again, but success rates drop to 30-40% for recurring stuck pixels.

"Had a green stuck pixel on my Dell S2721DGF. Ran the flashing tool for 20 minutes and it's completely gone. One month later, still perfect. Saved myself a return."

"Tried software for an hour with no luck. Then tried pressure method with microfiber cloth and stylus — 10 seconds and the red pixel was gone. Be very careful with pressure!"

Partial SuccessTom's Hardware forum

"3 blue stuck pixels on my ASUS TUF. Ran the tool for an hour, fixed one. The other two are still there but near the edge. Can live with it."

Fix FailedUser review

"White stuck pixel (all sub-pixels). Tried software for hours, pressure, tapping — nothing. Manufacturer said white pixels are hardest to fix. Returned the monitor."

Recurred After FixForum post

"Fixed a green stuck pixel with 30 minutes of flashing. Two weeks later it came back. Ran it again and it worked for a month, then stuck again. Gave up and returned."

Frequently Asked Questions

What is a stuck pixel?

A stuck pixel is a pixel that displays a fixed color (red, green, or blue) instead of changing colors. Unlike dead pixels (black), stuck pixels may be fixable because the sub-pixel is just "stuck" rather than completely failed.

Does this tool fix dead pixels?

No. Dead pixels appear permanently black and cannot be fixed with software. They require screen replacement. This tool only works for stuck pixels (colored dots).

How long should I run the fix?

Run for 10-30 minutes per session. If the pixel remains stuck, try additional sessions. Some users report success after multiple 10-minute sessions over several days.

What is the success rate?

Success rate is approximately 30-60% for stuck pixels. Results vary depending on the cause and how long the pixel has been stuck. Recently stuck pixels have higher success rates.

Is it safe for OLED screens?

Do NOT run this tool for extended periods on OLED screens. Rapid flashing can cause burn-in. Limit sessions to 10 minutes maximum on OLED displays.

Why does flashing fix stuck pixels?

The rapid color cycling sends electrical signals that may "unstick" the liquid crystal in LCD panels or reset the transistor in the pixel. It works similar to massaging the pixel electronically.
