Размытые шрифты в Windows 10

Многие пользователи при обновлении до Windows 10 столкнулись с проблемой размытости и нечеткости отображения шрифтов в системе и некоторых приложениях, крайне мешающее при работе с компьютером. Как правило, проблема наблюдается на устройствах, с высоким разрешением, превышающем 200 DPI. Дело в том, что еще начиная с Windows 8.1, Майкрософт изменила применяемую ранее схему масштабирования DPI. Проблемы могут наблюдаться при значениях DPI, больше 120, а также у приложений, у которых отсутствует DPI-Aware флаг. Эта же схема масштабирования применяется и в Windows 10.

В том случае, если вы не удовлетворены отображением масштабированных шрифтов, возможно вернуться к «классической» схеме масштабирования как для одного конкретного приложения, так для всей системы (сброс и восстановление шрифтов при этом не поможет).

Устраняем размытость шрифтов для конкретного приложения

Если проблема с размытыми шрифтами наблюдается в одном конкретном приложении, например, в браузере Mozilla Firefox, можно попробовать решить проблему с размытостью шрифтов индивидуально для этого приложения.

1. Откройте свойства исполняемого файла приложения (в нашем примере firefox.exe)
2. Перейдите на вкладку Compatibility (Совместимость)
3. Включите опцию Disable display scaling on high DPI settings (Отключить масштабирование изображения при высоком разрешении экрана)
4. Сохраните изменения и запустите приложение.

Проверьте, устранена ли проблема. Если не устранена, переходите к следующему этапу – уменьшению системных настроек DPI.

Уменьшение системных настроек DPI в Windows 10

На многих устройствах проблемы размытости и плохой читаемости шрифтов наблюдаются в системе при использовании масштабирования 125% или выше. В этом случае стоит попробовать уменьшить настройки масштабирования шрифтов (DPI) до 100%.

1. Откройте современную панель управления настройками системы (Settings)
2. Затем в разделе Display установите ползунок Change the size of text, apps and other items (Изменение размера текста, приложений и других элементов) в крайнее левое положение (должно быть значение 100%)
3. Завершите сессию Windows и перезайдите в систему

Если и это не помогло – перейдите к следующему решению.

Возвращаем старый метод масштабирования в Windows 10

В Windows 10 и Windows 8.1 используется новая методика масштабирования отображаемых на дисплее шрифтов. Существует возможность вернуться к старому методу масштабирования, используемого в Windows 8 RTM и Windows 7. В большинстве случаев это поможет решить проблему размытости и некорректного отображения шрифтов.

1. Создайте файл revert_classic_dpi.bat со следующим текстом: REG ADD «HKCU\Control Panel\Desktop» /v DpiScalingVer /t REG_DWORD /d 0x00001018 /f
   REG ADD «HKCU\Control Panel\Desktop» /v Win8DpiScaling /t REG_DWORD /d 0x00000001 /f
   REG ADD «HKCU\Control Panel\Desktop» /v LogPixels /t REG_DWORD /d 0x00000078 /f
2. Запустите файл revert_classic_dpi.bat с правами администратора.
3. Перезагрузите Windows 10
4. Проверьте, исправилась ли проблема с отображением шрифтов

Windows scaling issues for high-DPI devices

Summary

When you use a high-DPI device such as a Surface Pro 3, Surface Pro 4, or Surface Book together with external monitors, you experience the following issues:

Elements such as applications, the taskbar, icons, toolbars, text, and dialog boxes appear to be fuzzy.

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.

These issues commonly occur in the following scenarios:

Applications are moved between monitors that use different display resolutions.

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 (RDC), and 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.

For more information about how Windows scales applications, see the following Core Team Blog articles:

Resolution

To resolve this issue, use the following methods.

Check for software updates Improvements are continuously being added to Windows 10 and Office 2016 applications. If you are experiencing a specific issue, first check whether it has been resolved in the latest Windows release or cumulative update. To check Windows 10 updates, see the following Microsoft Knowledge Base article:

Match screen resolutions Consider deploying monitors that have complementary screen resolutions.

When you use multiple monitors (including when you dock or connect to remote screens), a greater difference in the resolution between the native device and external device is more likely to cause the issues to occur. For more information, see the following OneDrive presentation:

Use UWP applications Use or deploy Universal Windows Platform (UWP) applications instead of Win32 applications.

Modern (UWP) apps always scale correctly. If there is a comparable modern app available, you can substitute that app to mitigate the scaling issues. For example, Edge is a modern app that does not cause the DPI Scaling issues that Internet Explorer might experience. Similarly, Remote Desktop is an alternative to mstsc.exe.

Check for known issues See the following articles for more information about known issues in these specific products.

Note Office 2016 applications started being released starting in September 2016. Additional updates are scheduled to follow.
Internet Explorer

3165808 Internet Explorer 11 Window display changes between built-in device monitor and an external monitor

Workaround

To work around scaling issues, try the following methods:

Log out and in Log out and log back in to the system. This improves how applications and elements are displayed when the monitor configuration changes.

Adjust display settings Windows 10

Select Display > Change the size of text, apps, and other items, and then adjust the slider for each monitor.

Earlier Windows systems

Right-click the application, select Properties, select 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 Properties, select the Compatibility tab, and then select the Disable display scaling on high DPI settings check box.

Note: In Windows 10 Version 1703 and later version of Windows, the text of the Disable display scaling on high DPI settings option is changed to Override high DPI scaling behavior, scaling performed by: Application.

Check whether applications are DPI-aware To determine an application’s support of DPI Scaling, follow these steps:

In Process Explorer, click the columns, and then add the DPI Awareness column to the view.

Start the application that you want to check.

In Process Explorer, locate the application, and then examine the DPI Awareness column.

DPI Awareness status definitions

Per-Monitor Aware: Per-monitor DPI-aware. These applications check for the DPI when they are started, and adjusts the scale factor whenever the DPI value changes. These applications are not automatically scaled by the system.

System Aware: System DPI-aware. These applications do not scale for DPI changes. They query for the DPI one time, and then use that value for the lifetime of the application. If the DPI changes, the application does not adjust to the new DPI value. It will be automatically scaled up or down by the system when the DPI changes from the system value.

Unaware: DPI-unaware. These applications do not scale for DPI changes. They are always assumed to have a scale factor of 100 percent (96 DPI). These applications are automatically scaled by the system at any other DPI settings.

For more information, see the following MSDN topic:

Report an issue Many UI elements have been updated because of customer feedback. Because DPI Scaling issues can involve multiple symptoms and configuration, information from users can help us identify specific scenarios and prioritize the development of updates.

To provide such feedback, follow these steps:

Record monitor configurations. To do this, take a screenshot of Display window ( Start > Settings > System > Display).

For each monitor, note the make and model, scaling percentage, and resolution.

Record the steps that you must follow to reproduce the issue.

Take screenshots or video of the desktop or applications before and after the scaling issues occur.

Run DXDiag.exe on the system.

Select Start > Feedback Hub. Search on “DPI” to check whether any listed issue matches your specific issue. If you find a match, you can add additional feedback, including screen shots, DXDiag results, and any other relevant information.

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 8.1, desktop environment and applications understand only one scale factor, generally based on the primary display at the time that the logon session starts. 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. This makes sure that content doesn’t become excessively large or small. 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. Third-party applications may require similar investments.

How to disable DPI scaling for certain built-in system applications?

On windows 10, most built-in programs work well with high DPI, but some don’t (the Hyper-V Manager for example).

For third party apps, I can change their compatibility settings.

How can I do this for a built-in app?

Try the solution given in this thread :

1) Open Notepad and paste in the following lines:

2) Save the file as DPI_FIX.cmd someplace easy for you to find.

3) Open the Group Policy Editor (enter gpedit.msc from the search bar).

4) In User Configuration, click on Windows Settings and then «Scripts (Logon / Logoff)».

5) Double-click «Logon» in the right pane.

6) In the Scripts tab, click Add, then Browse, then navigate to your .cmd file, click Open, click OK, click Apply, click OK.

7) Sign-out or reboot.

8) Login to your account. It may not take effect the first time, and if so sign out or reboot again. After that, it should work every time.

I suggest to first create a system restore point, just in case you need to undo this fix.

Another solution that is to be found on the Internet, is to use the program XPExplorer, whose use is described in the article Fix Fuzzy Windows 10 Text on High Resolution Displays, which does the above modifications on each login.

How to disable display scaling on high DPI setting for windows 10?

I just upgraded to windows 10 and noticed that some programs have the same issue with dpi scaling like on previous versions of windows (8.1/8/..). But on windows 10 I dont have the option (dont remember actually the name of it but was a check box nexet to the scaling setting) that fixed the problme for all the programs. In windows 10 i dont have that check box so I have to manually do the fix (right click->properties->compatibility->disable display sclaing on high DPI settings) for all my progmas but this works only for insitalled programs, I cant do it like for exampe: Device Manager so its blurry.

How ever I found out that if I set size of text, apps, other items to 150% will fix the issue, but I found out running that high on my notebook is making everything to BIG.

Hope that someone can help, thank you.

Thank you for your interest in Windows 10.

If you’ve enabled scaling and the text in an application is blurred or unreadable, then the only option is to disable display scaling for that particular application. As stated, right-click the application’s shortcut and then click Properties. On the Compatibility tab, select Disable Display Scaling On High DPI Settings, and then click OK.

You can also search «dpiscaling» and change the scaling settings in the display window. In the display window, you can click on set a custom scaling level option and check if it helps.

Hope this information is helpful. Do let us know if you need any further assistance, we’ll be glad to assist you.

Ok, I understand that the only fix for apps is by right click->etc. But for example how do I fix device manager witch is blurry?

Fantastic — dpiscaling fixed the problem for me! I just upgraded to Windows 10 from Windows 7. With Windows 10, text was fuzzy in all programs. Never had the problem before. I have a 1366 x 768 laptop screen. Selected 125% under DPI scaling «set a custom scaling level». Now all text is razor sharp in all programs in Windows 10, just as it was in Windows 7. Thank you!

This isn’t helpful.

There is no compatibility tab when I right click the application (in this case, Powerpoint) icon, nor does it show up under «properties». I’ve tried this step on everything from start menu icons, quick start bar icons all the way down to the .exe file.

Right-clicking the .exe file gives me something called a «Compatibility Troubleshooter», which at least references the problem (Troubleshoot program —> The program opens but doesn’t display correctly —>Test the program —> Next) but doesn’t actually let me do anything other than test run the program — which still looks wrong.

Generally changing dpiscaling doesn’t seem right, since it is only some of my applications that have this problem. For example, powerpoint, acrobat, calculator and my desktop icons seem to have this problem, whereas word, excel and chrome look great. Finally, dpiscaling’s minimum setpoint seems to be 100%; given that I want to reduce the size of icons not increase them this doesn’t seem useful.

Note that this is on Windows 10 Pro, running with Admin rights.

Scaling is a hit or miss kind of thing. So older programs never were designed for HD or higher screen resolutions. In order for display scaling to work in Windows 10 everything is set the same including those programs never intended to scale. This causes poor display issues for those programs, including blurry text, grainy and over sized windows. Sadly the choices are trying to make it a little better by disabling scaling for those programs, or fiddling with Windows 10 over all scaling so as those programs look better but will probably make everything else too small. I never realized this was such a problem until I bought my first HD laptop.

I had HD desktop monitors but they always displayed at 100% DPI so no real problems. It was no so with my laptop which has to raise DPI to 125% in order for everything to scale properly and not be too small. My wife actually has to scale her Envy laptop to 150% just so she can read some text. Of course this adds to the issues with older programs. These issues will be around for a while until all programs update and are designed to work with scaling.
