System Settings -> Display and Monitor
Recently helped a friend with vision difficulties scale up their desktop
elements/fonts to avoid eye strain(they had a condition that had optic nerve
damage where some vision was restored but is still quite limited). While not
HiDPI exactly, I think the scaling is still useful in this case for the 1080p
display? Cursor size and Font DPI were also increased.
In this settings window, I used the Scale Display button to try find a
comfortable size for the user. If the scale value was too high(I think 1.7x-2x)
some windows/dialogs were too big vertically, so while it was a more ideal
scale for them I had to reduce it as a particular dialog(native KDE app I
think, sorry can't recall what one) had it's apply/cancel buttons cut off, and
the titlebar likewise was cropped off desktop, I couldn't seem to
reposition/resize the window(I think there is a key shortcut for this but I did
not know it offhand nor expect a casual user to know about such and remember
it).
Some applications icons had a pixelated like look instead of a crisp aesthetic.
I understand scaling especially non-integer values can be responsible for this
on bitmap graphics, though I think it still happened with 2x on Octopi(Qt
package manager app). This also seems to affect some text, like when shutting
down or rebooting, the overlay with countdown and ability to change your
choice, the text here appeared pixelated. Yakuake was affected by it's bar with
close/menu/pin buttons, as well the red X above that.
Taskbar scaled great, as did window decorations(titlebar buttons here were
crisp).
I believe I noticed that this scale value was also adjusting Font DPI as when
we went to tweak it was at a value I don't recall setting, that was unexpected
since we started with Font DPI first, I guess that wasn't required.

Kudos to devs as the experience was less painful than expected.
I was mostly fine with google queries and exploring system settings, KDE
content on accessibility for such things is a bit spread out and dated from
what I gathered with findings described here:
