Distorted app screen and Black spots on screen sometimes

[Ravi-2000]

Some of the app screen suddenly gets distorted and black spots appears near it. The problem can be seen more frequent while in device manager. Other apps are also getting affected the same way. Tried updating windows (currently on latest version), tried updating display drivers, GPUs, also tried troubleshooting and hardware diagnosis but nothing is working. Please help.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I understand that your HP notebook display is not working correctly.

• When was the last time it worked without these issues?
• Have you updated Graphics and Chipset drivers?
• Have you checked the display on an external monitor?

Let’s try these steps to resolve the problem:

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

And, also run BIOS Update: Follow steps from the link: https://support.hp.com/in-en/document/c00042629
