The DPI setting of a display monitor is a measure of the number of dots that are visible in a single inch Dots-per-Inch or Pixels-per-inch. DPI is not the same as resolution. Resolution is the number of horizontal and vertical pixels. For example, x pixels. An image with x pixel resolution would be 1 x 1 inch when printed at DPI. When a display DPI is chosen in Microsoft Windows, you are telling the system how the attached monitor will display images, Windows will then rescale to take this into account.
The changes made by adjusting DPI are more subtle than changing screen resolution, but setting DPI correctly can be important for preventing eye strain when using high pixel density displays.
It is not advisable to set a DPI lower than 96 as the majority of Windows fonts are not hinted to display correctly at very small sizes. The option to ' fix apps so they're not blurry ' will turn off full scaling of non-DPI aware applications, which can cause fonts to become blurry. Setting the DPI for individual users connected to a terminal server or Citrix can only be done in the registry, if the DPI is changed in the Control Panel as above, then the change will apply to only the currently logged in user.

Though Full HD 1, x 1, and higher displays are much more common, 4K UHD 3, x, 2, displays are arriving on an increasing number of machines.
How To Change DPI Scaling Level for Display In Windows 10
This is measured by looking at PPI. Since then, displays have been shipped with significantly higher PPI, and a few problems have arisen because of it. Newer applications are more aware of high-resolution displays, and some developers have caught up with the times and have adjusted their older applications. Consider the following screenshot, which shows a 4K UHD set at its native resolution with the Windows 10 Settings app maximized. By increasing the display scaling, you can make on-screen items such as text and icons more substantial and more comfortable to read and use.
All the on-screen items such as text and icons are now much easier to view and manipulate. Step 2 : Look for the Scale and layout section in this window. Here you will see options for adjusting the size of your apps and text, changing the resolution Windows is set to, and adjusting the orientation of the screen. Changing the size of your text and apps is an easy way to adjust the scaling.
Sometimes, some desktop apps will look blurry when you change scaling and display settings and adjust for DPI. You have two critical choices in this window. The second is an option to add a custom scaling number for Windows to use.
Problems can arise with older Windows desktop applications. For earlier Windows systems, right-click on the application icon, such as via a shortcut on the desktop, and select Properties. Then, select the Compatibility tab. Under settings, click Change high DPI settings.
Doing so opens a new window where you can check off the Override high DPI scaling behavior box. There are three options for this setting, Application, System, and System Enhanced. We dive into those later. Consider the following application as it runs on a 4K UHD display set to percent scaling.
The first option, Application, will let the application control how it displays. This results in the same thing as if you have your Windows 10 system configured for percent scaling — notice how the icons under the menu are tiny. The second option, System, lets the Windows 10 system control things, which is the same as leaving this setting turned off. Third, you can select an enhanced version of system scaling.Skip to main content.
Select Product Version. All Products. Elements are too large or too small compared to the rest of the desktop. Blurry text appears in applications or in the Windows interface. Although these symptoms may be seen on a single monitor, they're more common when you use multiple monitors that vary in display resolution. These symptoms also occur when the hardware configuration changes, such as when you dock and undock a device that uses external monitors, or you detach an external monitor from the device.
The monitor that applications are displayed on changes between docked and undocked configurations. Users mix connections during the same logon session. For example, users log on through a remote desktop connection RDCand later connect directly without first logging off. Display information is determined when a user logs on to the system. A logoff-logon process resets the display information and improves behavior. However, the issue recurs if the monitor configuration changes during the same logon session, such as when you dock or undock the device or detach an external monitor.
This issue has become more prevalent since the introduction of 4k and higher resolution monitors, especially when these monitors are mixed together with older, standard monitors. Display Scaling changes for the Windows 10 Anniversary Update. Improving your scaling experience. Improved high-DPI support for desktop apps. To resolve this issue, use the following methods. Check for software updates Improvements are continuously being added to Windows 10 and Office applications.

Surface Pro 3 and Multi-Monitor Guidance. Office apps appear the wrong size or blurry on external monitors Note Office applications started being released starting in September Additional updates are scheduled to follow.
This improves how applications and elements are displayed when the monitor configuration changes.
Earlier Windows systems Right-click the application, select Propertiesselect the Compatibility tab, and then select the Disable display scaling on high DPI settings check box. Change application properties In Explorer or on the Start menu, right-click the application name, select Propertiesselect the Compatibility tab, and then select the Disable display scaling on high DPI settings check box.
More Information. Display scaling is a deceptively complex problem. There is no magic bullet or single fix to resolve all DPI Scaling problems. DPI Scaling benefits from continuous improvements in the core operating system, in application development models, and in applications from both Microsoft and third parties. Different versions of Windows and application development models have different display scaling capabilities and limitations.
For example, in Windows that were released earlier than Windows 8. When the display changes in the middle of a logon session, the system bitmaps scale content from the system scale factor to the new monitor scale factor. However, text may appear blurred. The effect is worse when you scale up. If the system shrinks or stretches UI elements to the correct size, this may cause some blurriness in dialog boxes and other UI elements.
In Windows 10, investments were made so that large parts of the desktop UX will scale crisply in docking-undocking scenarios. Additional scalability improvements were made to the taskbar, File Explorer, desktop icons, context menu, and other UI elements to improve the user experience. Microsoft is continuously updating the system and first-party applications.But if you want to change the default DPI scaling level for your display screen in Windows 10, then you can use the native feature of Windows This DPI dots per inch measurement is used to set the total number of pixels or dots per inch on desktop screen.
Do not get confused changing the DPI level with display resolution or zoom in feature. Your display resolution and zoom in level will remain the same. Only DPI level will change with this trick. This is a very simple method to change DPI scaling level for display. Do note that this will work only if you are using Windows 10 Creators Update.
Step 1: Start the modern Settings app of Windows That option has multiple sub-options available under the separate sections. Step 4: The step 3 is quite helpful if you want to change DPI scaling level for current display. Note: The custom scaling size is applied only when you sign out or restart your Windows 10 PC.
The dark mode beta is finally here. Change your preferences any time.
How to adjust high-DPI scaling in Windows 10
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Its just a tool for me to beable to toggle scales from the tray, as its something I often have to do for testing.
So purposely designed for this action. However, obviously working with the registry directly means I need to restart the machine to take affect. Here is my learning from the RnD I did on system settings app immersive control panel.
I used WinDbg to go through calls made by this app. I found that as soon as a particular function is executed - user32! I wasn't able to set a break-point on this function, but was able to set one on DisplayConfigSetDeviceInfo bp user32! DisplayConfigSetDeviceInfo msdn link is a public function, but it seems that the settings app is sending it parameters which are not documented.Windows 10 Dpi Scaling Fix - Windows 10 Resolution Scaling
Here are the parameters I found during my debugging session. While the settings app is trying to send -4 for type, we can see that the enum has no negative value. It seems incredibly unfair that Microsoft has some special API for its own apps, which others cannot use. Sure enough, the DPI scaling did change on running the code!!! If we check the registry entries mentioned in Dodge's answer, we come to know that these integers are stored as DWORD, and since my computer is little endian it implies that the last 4 bytes bytes 21 to 24 are being used for them.
Thus to send negative numbers we will have to use 2's complement of the DWORD, and write the bytes as little endian. For any monitor, the DPI scaling value selected by a user is stored at :.
I was able to figure out the structure of monitor ID. I verified my theory with 4 different monitors. If some of the data required for constructing monitor ID are not present, then OS uses fallback.
The fallback for each of the datum required for constructing the monitor ID, as I observed on my Windows 10 machine are given in the list above. The registry method suggested above should work fine in most cases, but has 2 drawbacks.
How To Change DPI Scaling For Display From Windows 10 Settings
One is that it doesn't give us parity with system settings app in terms of the time at which settings are effected. Secondly in some rare cases not able to repro any more I have seen that the Monitor ID string generated by OS is slightly different - it has more components that shown in the pic above. Will post in a new answer, as this is more about the approach I took for finding a solution. I was able to reverse engineer system settings app, and come up with an API.
Super User is a question and answer site for computer enthusiasts and power users. It only takes a minute to sign up. I've got a laptop with a x display, connected to 2 external p monitors.
I would like to find a command that emulates the setting here, such that I don't need to right click on the desktop and open display settings every time I unplug my external monitors:.
Below is a batch script that will emulate the keyboard strokes to manipulate the GUI to adjust the Scale and layout options and Change the size or text, apps, and other items when it runs. This uses ms-settings:display to open the Display screen, and then it presses the tab key once and the up arrow 5 times using sendkeys to adjust the scale accordingly. This method builds a dynamic vb script with a batch script and then executes the vb script with cscript to emulate pressing the keyboard keys.
