How to make Windows 10 draw a window at 100% scaling, rather than 125%?

0

I have a small, high-resolution display that is set at 125%. However, one program I want to run consistently draws it's start screen at 1024x768, which is a tad too big for my screen.

I want this program, and only this program, to render at 100% rather than 125%.

THIS IS NOT A DUPLICATE. This program is DPI-aware and thus "Disable display scaling" won't work on it.

So, I see two options:

  1. Tell Windows to inform this program it's running at 96 DPI, and draw it as such.
  2. Have Windows scale the program down to fit.

How can I fix this?

If is is a high resolution screen how can a 1024 by 768 window be too big? What program is it actually? – Seth – 2017-08-01T11:31:33.013

@Seth Open Rails Train Simulator. The screen is high resolution but it's resolution is only 1280x800. The program fits if I set DPI scaling to 100% for the system. – None – 2017-08-01T11:32:17.093

According to the documentation you could choose to run it "Full Screen" or you could use configuration options/startup parameters to set the actual resolution for the window. You could also check Set DPI of individual applications in Windows.

@Seth unfortuantely that's not the problem. the issue is the Menu.exe screen, not the game itself. – None – 2017-08-01T11:41:06.733

"Set DPI of individual applications" only works for non DPI-aware applications. – None – 2017-08-01T11:41:51.693
