External monitor 1080p or 4K?

[Quarnero]

What counts is that you have appropriate/basic link (as based on experts testings) where is relatively easy to find up-to-date monitor, in accordance with your own preference(s). Here is about: https://tftcentral.co.uk/reviews/viewsonic-xg2431.

And yes, I do agree that 1440 px is indeed great number:

Just small side note on basic laptop screen resolution, as might be that people keep forgetting that most important (presented on smartphone and laptop screen, other than family living room and public big ones) is vertical resolution of 720 (HD) that multiplies (upscale) with ×2 or ×3.

I’m using the ViewSonic VP2458 monitor

EDIT: Test ViewSonic VP2458, although in German (but still my very favorite site): Monitor Test ViewSonic VP2458 - Prad.de.
