Touchscreen edges lighter

[winter_v1]

Hi ! So I recently noticed some lighter zones on my screen; I have a HP Envy x360 with touchscreen, so obviously I'm working on the screen, and that brightness difference is pretty annoying.

It can be seen better on a dark background, not at all on white.

It started with only a small zone in the corner of the screen, but it is now visible on a larger zone and I'm afraid it might go to the rest of the screen...

It doesn't affect the responsiveness of the touchscreen.

If you have any idea of what this might be...

Thank you for your time ! 🙂

Hi@winter_v1,

Welcome to the HP community 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post you're having issues with the display on your HP Omen notebook. Don't worry we'll work together to help you find a solution.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the PC before the issue started?

Did you check for any damage on the PC?

Have you tried to update the drivers either using Windows update or using HP Support Assistant.

Have you checked if the issue persists even in the Bios screen?

Have you checked connecting this laptop to an alternate monitor?

For now let's try these steps here: 

Step 1: Performing a hard reset

Step 2: Connect an external monitor to test the display:

The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

Step 3: ​​​​Boot the computer into the Bios screen and check if the screen persists.

1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the  F10 button repeatedly

Once you are in the BIOS, if the screen issue persists, it is likely a hardware failure.

If the screen backlight issue is not present in the Bios, then this could be a software or driver issue. 

Let's restart the computer and then uninstall the display drivers from device manager: 

Use shortcut keys Win + X on Windows 10

Select Device Manager.

Expand the entry. Right-click the problematic device and select Uninstall device.

You may need to check the option Delete the driver software for this device, and then click the Uninstall button.

Now restart the computer and then update the Bios, Chipset and graphics card drivers on your PC from our HP support website, using this link.

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

If the issue persists, I would suggest the next step would be to run a test an extensive test on the graphics card which is listed under Component test

You could also try to run an extensive test on the system. (Please capture the failure ID for further assistance).

For more assistance, please follow the steps suggested in the support document for - HP Notebook and All-in-One PCs - Troubleshooting Screen Issues (Windows 10, 8, 7)

Hope this helps! Keep me posted.
