Vertical Line & Small Box in 5400 AIO Monitor
Inspiron 5400 AIO
Out of the blue yesterday a vertical line appeared on the left side of the monitor. I recently did a format and clean install of Windows 11, as well as replaced the old RAM with 24GB of Crucial & PNY.
I can't find anyone who has run into this or any possible explanations. Dell says to power down and then press and hold the "D" key as the computer restarts and it would go into screen calibration mode: Nothing happened, it just booted like normal, line and all.
I've included a screen shot (the issue is highlight by a red box, which itself is not part of the problem), in case anyone can identify this issue. Thanks!

Make sure you hold the D key completely through the powerup -- a series of self-tests should begin. Alternaitively, tap the F2 repeatedly after pressing the power button until you get into Setup. Does the fault show on the test screens and/or in setup?
