27" HD display/monitor - thoughts

As I mentioned here I bought a new monitor to use as a 2nd display with my current laptop.
Ever since I started working with 2 monitors I can't go back to just one...


Anyway, it's a 27" monitor with a max. resolution of 1920x1080 (Full HD, 1080p).


Had I known/realized how crappy the support in Windows is for adjusting DPI
for large displays (as well as different size displays)
I probably would have bought a 23" 1080p monitor rather than a 27"
or waited/spent a bit more and bought a 27" with higher resolution.

The smallest DPI setting that Windows (8/8.1 and also currently 10) support ist 96dpi.
That is still too large for a 27" display, 80...86 dpi would probably be useful,
but there's no way I could find to force Windows below 96 dpi, not even with registry tweaks.


My Acer laptop has a 15.4" Full HD screen.

Close up (normal laptop working distance) 96dpi are good.
Having it on a stand further away now means I would need ~110dpi to make it easily readable.
The 27" at this dpi setting would probably be good for a legally blind person.
Fonts are huge, I feel I have to turn my head when reading to follow the text.

With some fiddling in Win 8.1 I was able to set the laptop screen to 125% (that's what Windows calls it) and leave the 27" at 100%. (That setup was easier to achieve in Windows 10).
But I feel all Windows does to achieve this is to simulate a smaller resolution on the smaller screen to make things appear larger. Text is a bit blurry, the picture isn't very crisp overall.
 So, in short, if you're going above 23" with your monitor consider spending more for a screen with more than 1920x1080 resolution to make use of all that area in a better way.

I'm dual-booting with Linux now and I think I should be able to tweak Linux to give me what I need...
