There are a lot of articles with how to make older version of windows with DPI scaling under 100%.

But when I try those methods on Windows 8.1 it is automatically returning me to 100% dpi after restart or sign out.

Changing a DPI to less then 96 DPI (which is 100%) can be done with Windows 7 and 8.

But can it be done with Windows 8.1 ? Did anyone manage to do that ?

I'm sorry if this is a bit nit-picky, but DPI is not a percentage, its a measurement (dots per inch). I think Windows defaults to 96 DPI usually. Please try and be clear what you're wanting to change in your question. –  heavyd Oct 24 '13 at 20:37

no i mean DPI. You can make DPI less in Windows 7 and Windows 8 by changing LogPixels in Registry but that doesn't work for Windows 8.1 so i am asking for help how to do that in Windows 8.1 –  Vuk Vasić Oct 24 '13 at 20:38
I know that 96 DPI is default but i want to change it to 86. That is possible with Windows 7 and Windows 8. I am looking for someone who have done that in Windows 8.1. –  Vuk Vasić Oct 24 '13 at 20:39
@heavyd pretty sure he is talking about these DPI percentages, you get to it by clicking the circled item. –  Scott Chamberlain Oct 24 '13 at 22:07
