New HP Pavilion x360, screen glitching when watching videos

[Henley-Taylor]

I just bought a new laptop earlier today, an HP Pavilion x360. I had no problems setting it up and jumped right in to using it. I logged into YouTube and started watching videos and noticed they were glitching every so often. I turned the computer off and back on again but it continued the glitching, so I decided to check other forms of video playback (Amazon Video, Netflix, Hulu) and the glitching continued throughout all the different videos/tv shows/movies I tried playing. I have not changed any settings or drives or anything, just pulled it out of the box, removed the plastic, and logged in.

Firstly, let's perform Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (do not skip any troubleshooting steps even if you feel steps are repeating)

3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. If the issue persists, follow the next steps.

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.
