I think it's really confusing if UHD devices like 4k monitors and smartphones get listed under visitor devices with the "wrong" resolution. As stated in #10296 it does make sense from a website point of view but in this way you can't differentiate between HiDPI devices and normal devices. E.g. it could be worth or necessary to provide images on a website with higher resolutions if more and more users with HiDPI displays are going to visit a website. With the current state this could not be tracked.
A solution could be to simply record both, the real screen resolution, which should also be presented under the device informations, and the "actual" resolution / viewport size.
A devicePixelRatio report could be good as well 👍
So I have implemented a plugin for reporting statistics on the device pixel ratio here:
It does not change the screen resolution report at all. This is how it should stay IMHO, it would make sense though to rename "Screen Resolution" to "Screen Size (in CSS pixels)".
A code review of my plugin by an expert would be appreciated. I'm currently testing it on my private Matomo instance, it seems to work fine. If everything goes well, I would enroll it to the Marketplace in a week or so.
