Sorry.. but a question that takes 6 years to acquire the "Notable question" badge is not a well trafficked question.
Those 3K views (and the badge) just means some combination of words hit your question rather than the more technical, and appropriate, duplicate.
It's not a bad thing to funnel searchers to a more in-depth answer.
If any question at any stack is there long enough.. it will trigger the "notable question" badge. The badge doesn't really mean anything. It certainly doesn't mean the question is more valuable.
I'd point out that the (open) duplicate also garnered the "Notable Question" badge. In fact, 5 times as much as your question.
The original question posted by @DA01 was specifically created because we were getting a lot of "what resolution" questions at the time. And rather than having essentially the same answers across myriad questions, the answers were intentionally more in depth and technical for that question so it would serve as a "holding space" for answers to any of the various "what resolution/ppi" questions. In other words... the "duplicate" was posted intentionally to drive less technically phrased questions regarding the same issue to it.
