Laptop Screen Flickering — Causes, Fixes & Repair in Singapore
Have you noticed your laptop screen flickering when watching videos, browsing, or even at startup?
This issue is more common than you think and can stem from software settings, display cables, or screen hardware.
If you’re in Singapore and your laptop screen keeps flickering, here’s how to identify the cause, fix it safely, and know when to seek professional repair help from Volta PC Upgrade & Repair.
What Causes Laptop Screen Flickering?
Display Driver or Software Conflict
One of the most common culprits behind screen flickering is a faulty display driver.
Outdated drivers, corrupted system updates, or incompatible refresh rate settings can cause your laptop display to blink or flash irregularly.
Try updating or reinstalling your graphics driver via Device Manager.
Loose or Damaged Display Cable (LVDS / eDP)
Â
If your screen flickers when you adjust the laptop lid angle, you may have a loose display cable connection.
The cable running from the motherboard to the screen can get worn out or oxidized over time, especially in Singapore’s humid climate.
This usually requires a professional inspection, not a software fix.
Faulty Laptop Screen or Backlight
Â
If your screen flickers under certain brightness levels, your LCD panel or backlight may be failing.
A technician can confirm this by testing your laptop with an external display.

Power Supply or GPU Problem
Unstable power voltage or GPU instability can also cause flickering.
Try unplugging the charger and running on battery power, if the flicker stops, your adapter or GPU could be the issue.

How to Fix Laptop Screen Flickering at Home
Step 1: Update or Roll Back Display Driver
Go to Device Manager → Display adapters → Update driver.
If the issue began after a recent update, try rolling back instead.
Step 2: Check Refresh Rate (Hz)
Go to Display Settings → Advanced Display → Display Adapter Properties → Monitor tab and ensure the refresh rate is 60Hz (or your laptop’s default).
Step 3: Test with an External Monitor
Connect your laptop to another monitor or TV.
If the external display looks fine, it’s a hardware issue (screen or cable).
Tip: If your screen flickers only when moving the lid, it’s almost always a hardware issue, not software.
