Thank you! We have received the required details.   A monitor exchange was setup today. We have sent you the details via private message.
There is a problem with my Dell S3422DWG monitor. Many thin horizontal lines have permanently appeared on its screen, and are still present even in the self-diagnosis mode when disconnected from the computer. Support was initially helpful, and were going to put me into contact with someone who could send me a replacement. I was told all that I would need to do is supply a picture of "the back of the monitor, including its two QR codes, and a piece of paper with my name and case number on it". So I provided that picture. They said it was too blurry. So I provided another one. Rejected. Another one. Rejected. Another one. Rejected. All in all, I sent THIRTY DIFFERENT PICTURES to Dell Support - at one time completely filling up their Inbox! - and each and every single one was rejected. And all support will do is ask for the same picture again. Sometimes after a delay. Usually with the same form letter, though occasionally with an apology. I have a lousy cell phone camera and a mounting on the extremely heavy monitor that semi-obscures the QR codes; the picture IS difficult to take. I've spent about 5 hours taking various pictures and sending them. I have broke about $150 of other electronics trying to take that stupid picture. I am DONE trying to take more versions of that picture. What I have sent is more than proof enough that I own that monitor. I have sent them all the information in text form; and also annotated atop an edited version of one of the clearer pictures, alongside greatly magnified versions of the QR codes. Nothing seems to make the slightest impression on support. Can someone PLEASE help me get past this picture request? Here is my info:
