I have a 4k monitor on my laptop but I regret that choice.
If you need fractional scaling, only native Wayland applications work well. X11 applications are going to be upscaled and look blurry. Today, Chrome, all Electron apps, Jetbrains tools still do not support Wayland, though at least for Chrome/Electron the support is on the way.
* Concerns about power
* Concerns about HiDPI issues / fractional scaling, esp. with Linux
* Likes seeing pixels
* PriceI enjoy gaming on my laptop, and prefer native resolution gaming.
I require a high refresh rate due to post-concussion syndrome. So sure, if that can be the case with a higher resolution that's fine, but that isn't the norm yet. (2021 seems to be the year for QHD 165Hz though!)
I'm in no way saying QHD or 4K isn't ideal for anyone. It's just silly to say that "this option I don't want is a non-starter" as if it applies to everyone.
3/2 is the best ratio ever when writing code (after 4/3, but that’s definitely dead).
