360hz monitor has blue and white vertical lines after a week of flickering

so i got the new 360hz pg259qn when it came out on septemeber 29th, since the day it arrived it has had flickering screen issues weather im playing a game or just watching something on like twitch or some shit. now it is october ninth 2020 and my screen (brand new btw) has blue and white vertical lines that desaturate the picture on my monitor. ive tried changing the port type, different chordes. now what i dont get on top of this randomly happening after working all day, it was shut down chillin for the last 10 hours and was working before i left for work this very morning. ALSO when i reset the monitor (turn it off and then back on) the colour shows on the "REPUBLIC OF GAMERS" boot screen, everything is white red and black as god and asus intended but as soon as windows unlock screen is up no proper colours and the distortion is there and you cant even tell what the hell the screen says it all types of messed up...please someone for the love of god help. this monitor costed me 700 fuckin dollars man :((((((((
