You've spotted a bright red, green, or white dot on your screen that won't go away no matter what you open. Before you contact tech support or assume it's a dead pixel, there's a good chance you're looking at a stuck pixel — and a flashing color video might fix it in an hour or two.
This guide explains exactly how stuck pixel fix videos work, how long to run them, and what realistic success looks like. The first step is confirming you actually have a stuck pixel rather than a dead one — because the fix only works on one of those.

Stuck Pixel vs Dead Pixel: Why It Matters Before You Try Anything
These two terms get used interchangeably, but they're fundamentally different problems with different causes and completely different fix options.
A stuck pixel happens when the liquid crystal molecules in one pixel subunit freeze in a single orientation. The transistor still works — it just can't switch the crystal anymore. Because the transistor is active, the pixel stays locked on: you see a persistent red, green, blue, or white dot.
A dead pixel happens when the transistor physically fails and stops receiving power. The pixel goes dark permanently. You see a black dot that stays black on every background color.
| Feature | Stuck Pixel | Dead Pixel |
|---|---|---|
| Appearance | Bright color (red, green, blue, white) | Black dot |
| Visible on all backgrounds? | No — may vanish on same-colored screens | Yes — always black |
| Transistor state | Working but frozen | Failed |
| Fixable with flashing video? | Sometimes (20–40%) | No |
| Fixable with pressure method? | Sometimes | No |
If your dot is bright and colorful, continue to the fix methods below. If it's black on every solid-color background, stop here — check your warranty options instead.
How Stuck Pixel Fix Videos Work
The idea is straightforward: rapidly cycle through primary colors (red → green → blue → white → black) faster than the liquid crystal can naturally follow. The constant high-speed switching agitates the frozen molecules, potentially shaking them loose from their stuck orientation.
Think of it like a stuck drawer. You don't pull hard in one direction — you work it back and forth quickly until it loosens up. The flashing video does the same thing electrically to the liquid crystal layer.
Dedicated tools like JScreenFix run these color cycles at roughly 60 cycles per second directly in your browser, targeting a small area around the stuck pixel. Longer YouTube "stuck pixel fix" videos do essentially the same thing — rapid RGB cycling — but at video frame rate (24–60 fps), which is slower than a purpose-built tool but still effective for many cases.
Which tool to use
JScreenFix (free, browser-based) runs the fastest color cycling and lets you drag the repair zone over the specific pixel. It's the best starting point. YouTube fix videos work too but are less targeted — use them as a fallback or when JScreenFix doesn't help after 2 hours.
How Long to Run the Fix Video
This is where most people give up too early. A 5-minute run rarely works. Here's what the evidence from user reports suggests:
| Run Duration | What to Expect |
|---|---|
| 0–30 minutes | Low success. May see pixel flicker — that's a good sign. |
| 1–2 hours | Most reported successes fall in this window. |
| 4–8 hours | Worth trying for stubborn stuck pixels. Run overnight. |
| 12+ hours | Diminishing returns. If not fixed by now, it likely won't be. |
If you see the stuck pixel flicker or change color mid-session, that's a positive sign — the liquid crystal is responding. Keep running the fix for another hour even if it looks like it unstuck, to reduce the chance of it locking back up.
OLED screens: limit to 2-hour sessions
On OLED monitors or OLED phones, running a stuck pixel fix video for extended periods (especially if it's bright white) adds stress to the panel. Cap sessions at 2 hours on OLED, take a break, then run another session if needed. LCD/IPS/TN monitors can safely run overnight.
Step-by-Step: Run a Stuck Pixel Fix
On a monitor:
- Open JScreenFix in your browser (search for it — it's free and runs without a download).
- Click "Launch JScreenFix" and let the flashing square appear.
- Drag the repair zone directly over the stuck pixel using your mouse.
- Let it run for at least 1 hour without interruption.
- Check the pixel afterward by running our full-screen color test.
- If still stuck, repeat for a 4-hour session before giving up.
On a phone or tablet:
- Search for "stuck pixel fix" in your app store — several free apps cycle colors in a small movable window.
- Position the cycling window over the stuck pixel.
- Run for 1–2 hours. Keep the screen plugged in so it doesn't dim or lock.
- Check by opening a solid white image, then a solid black image.
The Pressure Method: A Complement to Video Therapy
If the video approach alone isn't working after a couple of sessions, some people report success combining it with gentle pressure. The pressure physically nudges the liquid crystal molecules while the flashing video keeps them electrically agitated.
Do this carefully — excess pressure can damage the panel
This method risks creating more stuck or dead pixels if done with too much force. Use it as a last resort on a monitor that's already out of warranty, and never apply pressure directly with your fingertip — always use a soft cloth as a buffer.
- Turn off the monitor completely.
- Fold a microfiber cloth into a small pad.
- Apply very gentle, circular pressure over the stuck pixel for 10–15 seconds. Think "barely touching" — not rubbing.
- Turn the monitor back on while still applying light pressure.
- Release and check if the pixel has changed.
- Follow immediately with a JScreenFix session.
For a great microfiber cloth that won't scratch your screen:
Ultra-soft 6-pack that's safe for LCD, OLED, and phone screens. Ideal for the pressure method and general screen cleaning.

What Realistic Success Looks Like
Anecdotal community reports (Reddit, Tom's Hardware forums, display manufacturer threads) suggest somewhere in the 20–40% success rate for genuine stuck pixels. That's not a guarantee — but it's meaningful enough to spend an hour before assuming the worst.
The pixels most likely to respond are those that are newly stuck (within the past few days) and appear on LCD/IPS/TN panels. Old stuck pixels that have been locked for months are harder to fix. OLED pixels that appear "stuck" are actually more likely to be early burn-in — which won't respond to this method.
If the video method doesn't work after a 12-hour total run across multiple sessions, it's time to move on. Check your monitor's dead pixel warranty policy — many brands will replace even a single stuck pixel within the first 30 days of purchase.
- Stuck pixels (bright dot) respond to flashing video; dead pixels (black dot) don't.
- Run JScreenFix for at least 1 hour — most successes happen in the 1–2 hour window.
- OLED panels: cap at 2-hour sessions to avoid burn-in risk.
- 20–40% success rate on genuine stuck pixels — worth trying before warranty claims.
- If it fails after 12 total hours, check your warranty — most brands cover stuck pixels within 30 days.
