Dell P2414H, vertical green line an inch/inch and a half into the screen that stops short about half an inch from the top of the monitor. Image looks as if it's made of fabric and has light static to it. Sometimes fades to black and silhouettes the things on the screen. Moving cursor across while the screen is black yields black lines moving with it.

Likely not the power cable or DP cable despite it reacting like it is. Highly doubt I damaged the screen by pressing on it.

Any ideas? I still have about a year left on the warranty, but I do not have access to the service pin. Serial number isn't good enough for Dell Support either, so I'd rather fix it myself than deal with them again.
