Laptop screen suddenly has a myriad of horizontal black lines

[pmonett]

I have an ASUS ROG STRIX I7 G713QR-K1153T since november 2021. It has been working fine, every day, until today, out of the blue, the screen wobbled and suddenly I have a black line every ten pixels or so.
It is quite a nuisance for work.
Is there anything I can do, or is this a case of bring the laptop in for repair (as in, replace the screen) ?

Thank you for your opinion.
