Black screen with vertical lines

Hi there!

So I recently purchased a Gigabyte G5KD laptop (i5-11400H / RTX X3060P) - it’s just over a month old.

I was watching Netflix in bed last night and all of a sudden the screen started rolling blurred grey streaks across it, then went black with nothing but these vertical lines appearing.

As you can see I plugged it into my monitor and it works fine, but the laptop display itself seems to be buggered. I tried resetting the graphics card but sadly I’m starting to think it’s a hardware issue - which is a crying shame considering how new it is.

Any clue what it could be? Is there anything I should do before I start considering taking it to get repaired?

Thanks
