Finding sudden black spots, shadows, or circles on your laptop screen can be really annoying and frustrating for users. These annoying marks seem to appear randomly, getting in the way of your work and distracting your eyes during the use of your device.
Although tempting, avoid punching or cracking your screen in anger over these pesky Graphics artifacts and display issues!
What is a Black Shadow on Laptop Screen?
A black shadow on a laptop screen refers to dark spots, marks, or areas that appear on the display. These black patches often show up randomly and can grow bigger over time. The shadows can take various shapes like spots, circles, lines, or large blotchy areas.
They are opaque black marks that block light from passing through that part of the screen, obscuring text/images behind the shadow.
What are the Causes of Black Shadows on Laptop Screen:
There are several possible causes of black shadows on a laptop display:
- Physical damage to the LCD panel – Cracks, dents, or pressure points on the screen can cause black spots or lines. This kind of damage usually occurs from dropping the laptop or impact damage.
- Liquid seepage – If water or other liquids get inside the display assembly, it can cause corrosion or short circuits that show up as dark patches.
- Dust buildup – Dirt and debris trapped between the glass and LCD matrix can also block light transmission.
- Backlight failure – When LED or CCFL backlight components start to fail, they produce uneven lighting which results in black shadows, especially around the edges.
- Ribbon cable damage – Video cables that get pinched, torn or become unseated can cause weird lines/distortion onscreen.
- Graphics card defects – A faulty dedicated GPU can start glitching and producing visual artifacts including black rectangles or shadows.
- Incorrect video settings – Wrong resolution, bit-depth, refresh rate etc. may manifest as shadow-like symptoms.
In this guide, we’ll go over the 11 best DIY fixes for black spots and shadows on a laptop display.
11 Best Ways to Fix Black Shadows on Laptop Screen
1. Update or Reinstall Display Drivers
Outdated, corrupt, or faulty graphics drivers are a common cause of artifacts and display issues. Updating to the latest video drivers can often resolve black spot problems.
- Open Device Manager and check your Display Adapter for any warning signs.
- Go to the laptop company’s support site and download the newest driver.
- Uninstall the old driver, restart your laptop, then install the new driver.
If updating doesn’t work, remove the current driver using DDU and install the newest version for a fresh start.
2. Adjust Screen Resolution and Refresh Rate
Incorrect display settings can sometimes contribute to shadow issues.
- Go to Start > Settings > System > Display.
- Under Resolution, move the slider to Recommended.
- For Refresh Rate, choose the highest rate available (often 60Hz).
- Click Apply and check if the spots disappear.
3. Modify Screen Brightness and Contrast
Overblown brightness and contrast can make shadows more visible.
- Lower the screen Brightness under Display settings.
- Also, reduce the Contrast ratio to 70-80% and enable Adaptive Brightness.
- Check if adjusting these dims the black spots.
4. Run Hardware Diagnostics
Faulty hardware like RAM, hard drives or dedicated GPUs can manifest as weird screen artifacts.
- Boot into the laptop’s built-in diagnostics suite from BIOS (HP, Dell, and Lenovo all have one).
- Run extended tests on the display, memory, drives, and GPU.
- Replace any hardware flagged as faulty.
5. Examine for Physical Damage
Carefully inspect the LCD panel and hinges for any cracks, dents, or malformations that may be causing black marks.
- Check under bright lighting for panel damage or backlight bleed.
- Look for cracks around the bezel edges and hinges.
- Press gently on spots and bezel to check for any movement.
6. Check and Reseat Display Cables
Loose display cables are a common source of screen artifact issues.
- If comfortable, open the laptop to access the ribbon cables.
- Unplug and reseat cable connections to the motherboard and screen.
- Check cables for damage – replace if required.
7. Clean the Screen
Dirt, debris, and stains on the screen surface can create dark shadow-like symptoms.
- Turn off and unplug the laptop.
- Gently wipe the screen with a microfiber cloth.
- Use distilled water or a 50/50 vinegar and water solution for tough stains.
- Avoid applying pressure and don’t use harsh cleaners.
8. Apply Pressure to Spots
For some types of LCD damage, applying light tactile pressure can temporarily improve the appearance.
- With the laptop powered off, gently massage the dark spots, exercising care.
- Try pressing from side angles around the spot rather than directly poking at it.
- This is only a temporary fix but may reduce the mark.
9. Use a Screen Protector
Placing a screen protector over the panel can help conceal shadows in some situations.
- Purchase a screen protector specifically sized for your laptop model.
- Carefully apply the protector centered on the display.
- Air bubbles can worsen the marks so apply slowly.
This will only mask, not fix the problem so consider replacing the LCD eventually.
10. Replace Display Panel
If the LCD panel itself sustains damage, you may need to replace the screen.
- Purchase a replacement LCD screen for your specific laptop make and model.
- Find a disassembly guide for your laptop and carefully remove the old display.
- Transfer over any undamaged components like the webcam.
- Install the new panel and reassemble the laptop.
Getting the correct replacement part is crucial for ideal fit and performance.
11. Use an External Monitor
If replacing the laptop screen isn’t feasible, consider using a secondary external monitor instead.
- Connect your laptop to a monitor or TV via HDMI, DisplayPort, or VGA.
- Set the external display as your primary screen under Display settings.
- Close the laptop and work solely on the external display.
While inconvenient, this may be a feasible temporary solution in some cases.
Trying these troubleshooting steps can often resolve black spot and shadow issues without requiring expensive professional repair. If you’ve tried everything and it didn’t work, you might need to get professional help for a hardware problem.
