Hi @Mahii21 

Welcome to the HP Support Community!

Thanks for posting your query! We're here to help you get back up and running.

Thanks for sharing the images! Based on what I see, your HP Pavilion 15-ec2004AX is experiencing significant flickering at 144Hz, while at 60Hz, the flickering is reduced but still shows some lining. 

Let's explore possible causes and solutions.

 

Possible Causes

1. Driver Issues – Outdated or incompatible graphics drivers can cause flickering.
2. Refresh Rate Mismatch – Some displays struggle to maintain stability at higher refresh rates.
3. Power Settings – High refresh rates require more power, and incorrect settings may cause instability.
4. Hardware Fault – If flickering persists across refresh rates, the display panel itself may be faulty.

 

Troubleshooting Steps

Step 1: Update Graphics Drivers

1. Open Device Manager (Press Windows + X, then select Device Manager).
2. Expand Display Adapters and right-click your GPU (NVIDIA or AMD).
3. Select Update Driver > Search automatically for updated driver software.
4. Restart your laptop and check if the flickering improves.

Step 2: Adjust Refresh Rate Settings

1. Right-click on the desktop and select Display settings.
2. Scroll down and click Advanced display settings.
3. Under Refresh Rate, select 144Hz and apply changes.
4. If flickering persists, try 120Hz (if available) as a middle ground.

Step 3: Change Power Settings

1. Open Control Panel > Power Options.
2. Select High Performance instead of Balanced or Power Saver.
3. Restart your laptop and test the display.

Step 4: Run HP Diagnostics

1. Visit the HP Support page and download the HP PC Hardware Diagnostics tool.
2. Run a Display Test to check for hardware issues.

Step 5: Check External Display (If Available)

1. Connect your laptop to an external monitor via HDMI or DisplayPort.
2. Set the external monitor to 144Hz and check if flickering occurs.
   • If the external display works fine, the issue is likely with your laptop’s screen.

If the flickering persists despite these steps, it may be a hardware issue with the display panel itself. In that case, replacing the screen might be necessary. Let me know how it goes! 😊
