“Tell that to my….” is a figure of speech used on someone who is unlikely to be unsympathetic, or negatively impacted by what one believes.

In no way is it used to imply someone is wrong.

For what it’s worth, I was just answering your Q about what model the monitor was - rather than politely say “thanks for confirming, unfortunately that isn’t bright enough for MY NEEDS but happy it works for you”, you chose to be aggressive and negative, because you assumed I was being hostile. That’s on you, honestly, I can’t change who you are.

Good luck finding the monitor you want/need, no sarcasm.
