A vertical line extending through screen of MacBook Air
I bought my MacBook Air in December 2019. I am noticing a vertical line extending from top to bottom of my screen since September 2019 (Pics attached). First thought it was a software problem as I noticed it after I upgraded the OS. Today I upgraded again to Big Sur. But same problem persisting. What should I do?
MacBook Air 11″, macOS 10.15
