Flickering lines on my MacBook Pro

I have columns of flickering horizontal lines on my screen. There are 6 columns, the lines are top to bottom in the columns, and they are mostly purple or light purple with some light blue lines interspersed.

Does this mean my monitor is failing

macOS Ventura flickering screen I updated my Macbook Air M1 to Ventura on Monday 24 Oct. Within a few hours my screen started to flicker. I rebuild the machine using a USB drive (Create a bootable installer for macOS - Apple Support) After a few hours it started again. I notice this happens when I am using IntelliJ Idea Ultimate. Has anyone else encounter this issue? Perhaps when doing something that will use up a lot resources? I don't mind going back to Monterey I just hate the long process of rebuilding/setting up a machine.

Using Samsung S27A80 external monitor(s) with 2019 MacBook Pro I have two Samsung S27A80*U monitors. I have attached them to my 2019 16" MacBook Pro using USB-C 3.1 cables. When I have two monitors attached, the MacBook frequently freezes, flashes vertical lines on the main monitor, then crashes back to the login screen. If I detach one monitor, then it stops crashing, but frequently freezes. It becomes pretty much unusable. Once I have all external monitors detached, the computer behaves normally. Has anyone else had experience with this issue? Is there something I'm doing wrong? Should I upgrade the cables (these are the USB-C cables that came with the monitors)? Am I SOL with these particular monitors? They're listed as Mac compatible. Thanks.

Not necessarily failing.

Any banding on a display can be the result of a frayed cable between the monitor and the logicboard or the graphics chip on the logicboard. The latter would be visible if you hooked up an external display.

AppleCare+ and https://support.apple.com/service-programs can help if you are covered under either plan.
