Feature request: Desktop scaling

[squadjot]

Would be cool if the program could handle scaling as well.

FYI: This is what I use for scaling:

Set-Scaling -scaling 0

You can comment out the last line and call this from another script by naming it as a .pm1 file and then using code like this in another script:

import-module .\powershell_modules\set-resolution.psm1
Set-Scaling -scaling 2

Note that he numbers (0, 1, 2) don't always line up with the % listed in the comments. This appears to be system dependent. You may even have to use negative numbers on some systems, which is detailed in the Microsoft link.

I took a look at this some time ago and I couldn't get anything consistent out of this API. From what I found out the scaling is system dependent so there's no direct way to specify a precise scale mode without a bunch of experimentation. Even on my system with multiple monitors the numbers were wildly different between the two monitors.

Hello Everyone. i have a little problem with DPI/scalling. after restart PC dpi is set to - for example - 150% instead of 100. Anyone have problem like this ?
