Why EDID is not trustworthy for DPI

[Matthew Garrett]

The heuristic isn't the problem. The problem is that we have no 
technology that allows us to handle the complicated case of multiple 
displays, and solving it purely for the simple case makes the 
complicated case *worse*. Adding additional complexity for what would 
be, at best, a different set of problems doesn't seem like a worthwhile 
way to spend time. The only people who are actively upset by the status 
quo are the ones who have the ability to fix it for their case, anyway.
