Hi i've been using this laptop for about 5 or 6 months now and have experienced little dots on my screen before. I looked it up on youtube and it said that my graphics driver was out of date so i went into device manager and right clicked Intel (R) HD Graphics 620 and updated it.

It worked like a charm so i was happy it resolved but it came back after i would say a month and it got so bad i can literally not type without a glitch popping up in the middle of a sentence.

this happened after i was playing a game of Fortnite when the computer starting showing random glitches that didnt let me see the player, i have no idea what to do now im pretty much stuck here at the moment, any feedback would help thank you.

Does the glitching line appear during your boot up process or after windows completes loading?

Do you have a warranty? I would rma it if possible

Yeah i do have a warranty but idk how i go about doing that
i went to the HP website and put in my serial no. and it says i have until September of 2018 till my warranty expires i have no idea of how to ask HP for a repair or replacement i am confused

It doesn't happen when it i boot up the system (hp logo) but it does glitch when it tells me to put in my password. its sort of like a line on the profile picture from then on the screen (background is full of little random dots)

its very annoying and i basically disable the display adapter Intel (R) HD Graphics 620 and it seems to fix the issue

i have tried everything even going to HP's website and finding another driver under the software & drivers section to no avail.

Wow, okay. that's a crap ton of dots you've got there. When you disable that adapter it fixes the problem? But you have a second adapter right? If so, just switch it to that adapter and use it, it's most likely gonna be your gpu chip since you're on a laptop. Anyways, if I were you, I would call HP Customer Service right now to issue rma since you're still under warranty or walk-in to any HP store.
