Have you ever noticed a black dot on your laptop screen or smartphone?
At times, it is really hard to remove those stubborn tiny marks from your screen, and it feels frustrating when the spots appear on your gaming monitor, as it reduces your viewing experience.
To know what kind of spots are Dead Pixel (not fixable) or Stuck Pixel (fixable), we need to test with the Whitescreen.Vip, an advanced white screen tool known for its top-notch features trusted by millions of tech users across the world for its flexibility.
In this article, we are going to share important information on how to use the white screen to check the dead pixels on your screen.
What is Dead Pixels?
A dead pixel refers to a pixel on a liquid crystal display (LCD) that does not light up and appears as a constant black spot. This issue can occur due to the pixel failing to receive power from the transistor, which is responsible for activating it. Dead pixels can be so annoying as they cause a distraction from work.
If, in case you have detected any dead pixels, then you will need a white screen tool to rectify them. Try the Whitescreen.Vip exclusively tests the dead pixel on your screen or device.
Before testing, let’s know the difference between a dead pixel and a stuck pixel
- Dead Pixel: A Dead pixel usually appears as a black spot on your screen, making it a permanent mark. It is mainly caused by a transistor failure.
- Stuck Pixel: A pixel that stays stuck on one color (red, green, blue, or a mix). Unlike dead pixels, stuck pixels may sometimes be fixed with software or light pressure techniques.
Using Bright White Screen the both issues are easier to detect, so that it is effective for the users to stay focused while using gaming monitors.
How To Check Dead / Stuck Pixels
Using White Screen, checking Dead Pixels or Stuck Pixels is quite simple without any complications. We share a simple process you can use on any device—desktop monitor, laptop, phone, or TV.
Step 1: Prepare Your Device
- Clean the screen with a microfiber cloth to ensure it is free from dust particles.
- Set display brightness to 70–80% for consistent results.
- Always recommended that you stay in a dim room to see the accurate results.
Step 2: Use a White Screen Test
- Open a whitescreen at https://whitescreen.vip/
- Scan the screen closely by clicking the zoom button below the white screen image.
- Once dead pixels are spotted, they will appear as tiny black spots that don’t match the white background.
- If you detect stuck pixels, they will display as colored dots.
Step 3: Cycle Through Solid Colors (Stuck Pixels)
Once you have identified stuck pixels, you may replace them with solid backgrounds one by one:
- Black Screen: It highlights stuck bright pixels.
- Red Screen: It reveals green or blue stuck pixels.
- Green Screen: It identifies red or blue issues.
- Blue Screen: Blue Screen detects red or green issues.
Step 4: Zoom In and Inspect
- Use the Zoom option by clicking (Ctrl +) camera if needed.
- Check for the stuck pixels that often glow brightly against one background but disappear on others.
- Whereas the dead pixels will never light up, no matter the background.
Step 5: Note the Location
- Make a note of where the dead/stuck pixel is situated (top-right, center, lower-left, etc.)
- This can help you plan whether the issue is fixed or not
Dead Pixels Best Practices
Test in Fullscreen Mode
Make sure to test the screen only in full-screen mode so you can view tiny spots clearly.
Check Multiple Brightness Levels
Some pixels appear only at higher or lower brightness. Test at 100%, 50%, and 25%.
View from Different Angles
Especially important for IPS or TN panels, where viewing angles change the color consistency.
Test More Than Once
Sometimes pixels appear temporarily and then recover. Run tests a few times over a week.
Don’t Confuse Dust with Pixels
Always wipe the screen before testing.
