Screen Flickering and now "Smudging" of old images / cursor movements

[ImOldGregggg]

The screen began flickering ~three weeks ago. Attempted to troubleshoot by updating graphics drivers which did not work. Flickering problem was made worse with increasing screen brightness. I can no longer change my screen brightness and the bottom 3/4 and right 3/4 of the screen now "smudge" images. If I  open an App with a white background and close it, the portion stays partially white. Same with mouse movements.

@ImOldGregggg Welcome to HP Community!

I understand that you are facing the Screen Flickering issue. 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

What HDMI connection are you referring to? is that an external monitor?

And is it the flickering on your laptop that stops or the monitor that doesn't have the flickering issue?

While you respond to that, here're a few things you need to do:

Please reduce or change the screen refresh rate to identify a difference:

1. Right-click the desktop and click Display settings.

2. Under Customize your display, at the bottom, click Advanced display settings.

3. Under Related Settings, click Display adapter properties.

4. Select the Monitor tab.

5. Under Screen refresh rate, select another refresh rate if available.

6. Click OK to save the changes.

If the issue persists, please follow the steps suggested on this link: http://hp.care/2sQmwBR
