I recently had a Dell monitor spaz out. Even powered off and powered back on, it was somehow keeping a (corrupted) image of what it had shown when last plugged in to my laptop. It's unclear how that's possible, but others witnessed it.

Had this been during something sensitive being displayed, it might warrant shredding that particular monitor. I have no idea how long the phantom image would have lasted. An hour, a day, a year?

Stored in the monitor control board somewhere.

Especially in the VRR era, monitors need to buffer the image in case it needs to be redrawn, or if the transfer rate is faster than the draw rate. Which will be anytime the monitor isn't drawing at max VRR sync speed.
