Screen flickers on startup and and when at lower brightnesses on homepage. At max brightness its ok

[ajayf1013]

Whenever I start up my Envy x360 Convertible (product number is X7U56UA#ABA) the hp logo flickers, then once i get to the login page to put in my passcode it stops, but then whenever i change the brightness to near and at its lowest setting it stars flickering violently. the error does not happen on my external monitor nor during BIOS. Ive also uninstalled my display adpater twice, and at first it fixed the issue for a solid few weeks, but then the issue came back and uninstalling it the second time didnt work.
