How to Set Display Custom Scaling in Windows 10

A new option in the Settings app allows you to set up Custom Scaling in Windows 10. Starting with Windows 10 build 15019, there is a text box which allows you to specify a custom value for scaling.

The Control Panel in Windows 10 still houses many important settings which are not available in Settings. You can use Administrative Tools, manage user accounts on the computer in a flexible way, maintain data backups, change the functionality of hardware and many other things. However, more settings are transitioning from the classic Control Panel to the Settings app in Windows 10. Advanced DPI scaling options were moved from the Control Panel to Settings in Windows 10 build 15019.

To Set Display Custom Scaling in Windows 10, you need to do the following.

  1. Open Settings.
  2. Go to Settings - Display.
  3. On the left, click the Custom Scaling link under "Scale and Layout".
  4. The Custom Layout page will be opened. Specify a new value for scaling percent from 100 to 500.

Once you configure the custom scale option, all your displays will be set to the custom size that you specified. This will change the text size, app windows and buttons. Basically, everything will be zoomed in. These settings can cause an issue if the display or some app does not support the scaling value you are trying to set.

Modern Win32 apps and Universal apps have no issues with scaling. Some older apps and certain popular legacy apps can became unusable or display their user interface blurred when you adjust the scaling options. In this case, there is a workaround. If you face an issue with some app which is not scaled properly, read the following article carefully:

This should help with certain apps.

Besides DPI scaling, these new Display options in Settings can be used to configure the display resolution.

  1. I really want to change dpi with the scroll thing what we have before.. because now our only option is 100% and above that, i really want go smaller, not larger scaling.

    I have one 4K display, one FullHD and one with 1050 resolution which is in pivot mode, these smaller displays i want to give something like 75 dpi so all the objects can be smaller on them. if i use that 100 scaller option, everyting is too big on these smaller screens but ok on that 4k display. This isint a very optimizing setup because of these new settings.

  2. The lower “DPI” you’re seeing on your QHD monitor is still 100% scaling, it’s just in reference to the 4K monitor itself. So, a 100px line will show up as 100px long on both the 1080p and the 4K monitor, it’s just that the 4K monitor has a higher pixel density, so 100px is compressed into a smaller physical space.

    You can’t really go lower than 100% scaling because then you run into rendering issues, especially where thin lines are concerned. For example, a 1px thin line will now have to be rendered at 0.6px for example, which never works well and everything looks gross.

    Still, you can try the effect you’re after by setting a custom resolution in the Nvidia or and control panel. Just make a 4K custom resolution for your 1080p monitor and you can get a feel for how terrible a DPI less than 100 would be.
