Surely most decent laptops being sold are HiDPI at this point?

Not as far as I'm aware, no.

But not real HiDPI. AFAIK Windows 10 just treats FullHD (1080p) as HiDPI and scales everything up to 125% by default but I always switch it back to 100% so I have reasonable screen space capacity. If the 13-inch displays were 4K that would be HiDPI.

  Traditional (~110 DPI, what Windows and MacOS were designed for) 13" resolution is 1280 or 1366. So 200% that is merely 2560+

    Ok, if it would be 2560 vertically on a 13" screen that's fair to consider it HiDPI but for 1280p on 15" this is questionable yet Windows does just this.I understand this is good for the vendors (who can claim they are selling you HiDPI - FullHD doesn't sound impressive enough anymore) and visually impaired people (that's actually great they are treated as the primary audience now). Perhaps this also is good as some sort of transition period so the technology gets introduced gradually while the screens still are not too dense and non-aware apps don't just become unusable instantly.

      We're talking horizontal resolution. No need for "p" obfuscation from the TV world!
      - qwerty456127 5y ago
        Ok, I thought we were talking about vertical an included the p specifically to disambiguate this. Practically 1080p just means 1920×1080 unambiguously (I know what does the p actually mean).

        It doesn't help that some laptops are 16:9 and some 16:10 so the vertical numbers get even more mushy. Anyway, my point was that even though "4K" as a concept has good mindshare, that's overkill even for a True Retina(tm) experience in the typical OSes on a 13". Around 100 DPI is what those UIs were foundationally designed for (starting in the 1990s) and all numbers unfold from that decision.

    Traditionally we had 85-100ppi monitors for example * 15 inches 1024x768 (85ppi) * 17 inches 1280x1024 (96ppi) * 19 inches 1400x1050 (92ppi) I'd argue that everything that is beyond ~140ppi needs adjustments in software and could be considered HiDPI. You could also argue that 200% scaling should be the threshold, if we're starting with 85ppi that would be 170ppi. It also depends on the viewer distance of course. Larger displays are usually viewed from a bigger distance.

      Yes, for bigger distances this makes a lot of sense. I want everything be as small as possible to fit more when I'm using my laptop but I would really appreciate decent unscaling on my RaspberryPi i use siting on the couch in about 3 meters from a 42-inch 1080p panel.

It all depends on who the user will be. Will it be a developer or will it be someone with a work laptop that has an 1366x768 screen?

There isn't a proper definition for HiDPI. Displays used to be around 100ppi. Nowdays, the majority of notebooks - even cheap ones - feature a FullHD display. For example when i list all notebooks on gh.de and limit the maximum price to 600€ of the 599 listed laptops 389 of them have a pixel density of 150ppi or higher. For a price up to 500€ it lists 306 laptops with 176 having 150+ppi.
