 display flipping continuously how to fix it

Hi Rahazul

That double image / vertical jumping effect on your HP EliteBook G6 is usually caused by either a faulty/corrupted graphics driver or a hardware issue (such as a loose display ribbon cable or failing LCD panel).

Here is a step-by-step troubleshooting guide to isolate and fix the issue.

 

Step 1: The BIOS Test (Isolate Hardware vs. Software)

Before changing settings, determine whether the problem is caused by Windows/drivers or physical hardware:

1. Turn off your laptop completely.

2. Press the Power button, and immediately press the F10 key repeatedly until the HP BIOS Setup screen appears.

3. Observe the screen carefully:

   • If the screen STOPS flipping in BIOS: The issue is software/driver-related.

   • If the screen STOPS NOT flipping (still glitches/flips in BIOS): The issue is hardware-related.

 

Step 2: If It's a Software Issue (Fine in BIOS)

1. Reinstall / Update the Display Driver

1. Right-click the Start Button and select Device Manager.

2. Expand Display adapters.

3. Right-click your graphics card (e.g., Intel UHD Graphics or AMD Radeon) and choose Uninstall device.

4. Check the option to Delete the driver software for this device (if prompted) and click Uninstall.

5. Restart your laptop. Windows will automatically re-install a standard driver.

6. Visit HP's Official Driver Support and download the latest display driver specific to your EliteBook model.

2. Change the Screen Refresh Rate

1. Go to Settings > System > Display.

2. Scroll down and click Advanced display settings.

3. Under Refresh Rate, try changing the value (e.g., switch between 60Hz and 48Hz or 50Hz if available) to see if the flipping stops.

Step 3: If It's a Hardware Issue (Flickering in BIOS)

1. External Monitor Test

Connect your laptop to a TV or external monitor using an HDMI cable.

• If the external monitor displays clearly without flipping, your GPU is healthy, confirming the fault lies in your laptop's built-in panel or cable.

2. Hinge / Flex Test

Gently tilt the screen backward and forward while looking at the display.

• If moving the lid causes the flipping to temporarily stop, get worse, or change pattern, the eDP display cable running through the hinge is loose, pinched, or worn out.

3. Hardware Repair Options

• Reseat the eDP Cable: If you are comfortable opening the laptop back panel, unplugging and firmly reseating the LCD display ribbon cable on the motherboard often fixes this.

• Replace the Screen Panel / Cable: If reseating doesn't work, either the display ribbon cable or the LCD matrix board itself needs replacement.

I hope the above is helpful
