Frequently asked questions

Is 27 inch better than 24 inch for work?

Usually yes if you want more screen area and a sharper QHD workspace, but 24-inch 1080p remains a common baseline.

Which size should developers test first?

Test viewport width first. Physical monitor size is useful context, but responsive CSS reacts to the browser viewport.

Is 1080p enough on 27 inch?

Many users prefer QHD at 27 inch because 1080p can look less sharp at typical desk distances.
