    How to Change DPI Scaling Level for Displays in Windows 10


    Dots per inch (DPI) is the physical measurement of number of pixels in a linear inch of a display. DPI is a function of display resolution and size; a higher resolution or a smaller size will lead to higher DPI, and a lower resolution or a larger size will lead to lower DPI. When a display has a higher DPI, pixels are smaller and closer together, so that the user interface (UI) and other displayed content appears smaller than intended.

    Windows ensures that everything appears on the screen at a usable and consistent size by instructing applications (including the Windows desktop shell) to resize their content by a scale factor. This number depends on the display DPI as well as other factors that impact the userís perception of the display. Almost all desktop displays and most current laptop displays are in the range of 95-110 DPI; for these devices, no scaling is required, and Windows sets a scale factor of 100%. However, there are a number of new devices, particularly in the premium laptop and tablet markets, which have higher displays with over 200 DPI. For these devices, Windows sets higher scale factors to ensure that the user experience is comfortably viewable.

    When you change the DPI scaling level for your displays, it changes the size of text, apps and other items to appear larger or smaller. A higher DPI level has everything appear larger, and a lower DPI level has everything appear smaller.

    The default DPI level is 100% (96 DPI).

    For more about display scaling, see:

    This tutorial will show you how to change the DPI scaling level for all or specific displays to make everything appear smaller or larger on the display(s) for only your account in Windows 10.

    When you use a DPI over the default 100%, the icons of the default folders under Quick access in the navigation pane of File Explorer will be on a folder instead of just an icon like below.

    If you have an app that doesn't scale properly when you are using a high DPI setting, then you could use compatibility mode to Disable display scaling on high DPI settings for the app.

    Brink, can I ask you something just out of curiosity?

    Your option 3, To Set Custom DPI Scaling Level for All Displays in Control Panel, after the .reg file has been applied, does it change the size of the Taskbar and Start Menu items', as well? So, if after applying the .reg file, you set a Custom DPI of 125%, will that get applied to the Start Menu items and the Taskbar icons, too?

    Because when I've tried the custom DPI setting on Win 10 Pro, without your .reg file applied, it changed the text size in the menus but not on the Start Menu and the Taskbar.

    Thank you.

    Hello Joanne, :)

    The selected DPI would be applied to everything. Did you sign out/in or restart afterwards to fully apply?

    The .reg file option is removed now, since it no longer has any affect though.

    Ah yes, you are right Brink, I'm sorry.

    The custom DPI setting does increase the size of everything. It does not resolve the blurry text issue on all those windows components and menus, though. I've already resolved this. Got confused, sorry.

    Yeah, it would be nice to set a custom SPI without risk of slightly blurry text.

    Unfortunately, the DPI problem in Windows 10 is very serious. I have many system windows and non-Microsoft programs that are extremely blurry. Using 125% DPI and the "Let me choose one scaling level for all my displays" setting which helped, is gone.

    This is the only solution that currently works for me - it seems that with every new Windows edition, more and more hacks and workarounds are required to make it work sanely.

    Interesting info here too, and an alternative fix.

    DPI scaling issue? Or something else?


    Guys, hoping that you will be able to help.

    I have tried all settings/tools available - WinAero Tweaker, Xplorer DPI and the Registry trick from this thread. However, the blurry text issue is not solved. Any thoughts could it be related to hardware/driver issue in my case (please see PC specs under my name/profile)? The display hardware is ATI HD 6650 which is built into the APU A8-3850. The PC is about 3~3.5 yrs old now. Also, the monitor is working on VGA rather than DVI, ever since my graphics card conked off (Sapphire ATI HD 7750).

    Please provide your thoughts.

    Update:
    Mild OC was enabled in the BIOS. The figure was set to 105% of CPU speed. This worked fine with dedicated graphics card. However, with in-built graphics, this does not seem to work. I remember this issue long back too with Win 7. When I increased the percentage to 101 or more, the font would become blurry. This is same issue with Win 10.
    Now, I have set the frequency to 100% and the fonts are much better. I cannot say that they are great, but they are much better. As someone mentioned, Win 10 bumps the DPI to 125% by default. So, everything seems bigger, but is also not as crisp. Hope this helps others who may have similar issues.

    Hello him,

    The VGA connection doesn't help, but anytime you change the DPI, I've noticed text to be a bit blurry. It appears to be a bug from not using the recommended (default) DPI and screen resolution.

    Using a Monoprice 30" monitor capable of 2560x1600 resolution connected with an HDMI cable to my PC video card.

    Followed your steps to set custom scaling level to 150%. This is necessary to make various windows and fonts legible on this large high resolution monitor. Bit this results in my resolution (as reported by Speccy) to fall from 2560x1600 to 1707x1067. [Control Panel shows screen resolution set at the native 2560x1600, as does the NVidia Control Panel.] If I remember right, this did not happen with Windows 7.

    How can I have larger legible fonts in all the programs and the desktop and still keep my resolution at 2560x1600?

    Hello Kumar, and welcome to Ten Forums. :)

    It may be an incompatibility issue with Speccy if it's showing the correct resolution in Settings and the Control Panel.

    I'm afraid that it seems blurry text is a side effect of setting a higher DPI so far. You might see if playing with different combinations of DPI and resolution settings may help. In addition, make sure you have the latest video driver installed. Next, you might all see if using the ClearType Text Tuner may help.
