Product: HP M22f FHD Monitor
Used the monitor earlier in the day it's fine. Come back a couple hours later to see a 1-inch rectangle of static on my screen. I did not touch the monitor and nothing bumped into it, so it happened on its own. I go to check the warranty and the website says my serial number is invalid. I went to the profile and tried to add it there it also says invalid. I have entered the code a ton I know I got it correct, and I also tried other browsers. Help Me fix it.
