External Monitor Settings Windows 10

by consmagdenadiapi 2021. 6. 7.


Troubleshoot issues that occur when setting up external monitors. If you are trying to set up an external monitor and it’s not working, press the Windows Logo Key + P to make sure that the Extend option is selected. If the Extend option is selected, try the following troubleshooting tips. You could also turn off the display, but it’ll still be connected and recognized by Windows 10. However, you can use the Settings app, to properly disconnect a monitor without unplugging the cable. In this guide, you’ll learn the steps to disconnect a monitor without having to unplug the cable or turning off the display on Windows 10. Doing so will tell Windows 10 to change the primary display to the monitor you have just chosen. Click on Apply, and the change you have made to your computer’s display configuration will be applied. Click on OK and close the Screen Resolution window. For Windows 10. In Windows 10, the steps are slightly a little different.

Windows 10 still can't do scaling properly. But there is a workaround for this. Windows 10 free upgrade.

  1. Connect the external display.
  2. Go to display settings and set your screen with lower DPI that has 100% scale factor as the primary screen (there is a checkbox at the bottom of this screen).
  3. Log out and log in. Now both screens should have crisp text.

If you disconnect external display you'll get blurry text on the laptop, but don't worry - if you log out and log in it should be fixed. If you connect monitor, you need to log out and log in again. It is annoying, but I did not find a better way and Microsoft just doesn't care.

Solution 1

To fix this issue, please check Start =>Settings =>System =>Display tab

External Monitor Settings Windows 10

Find the Scale and layout section and set the value of scaling at 100 % for each monitorIndeed, the scaling op the text can occured an blurry appearance.

WARNING : You must do these operation for each monitor (select the monitor 1, set the correct value then select the monitor 2 set the correct value, ..)

Solution 2

If you want scale the text, you can do but you must disable the display scaling on high DPI for each app who doesn't display correctly.To do that, You must find the exe of the application.Tips : to find easily the exe, right click on the app => properties => Open file location.

Do the following:

  • on the exe, right click
  • troubleshoot compatiblity
  • Troubleshoot program (second option) =>
  • Check 'The program open but doesn't display correctly'
  • Next
  • Check 'Program does not display properly when large scale font settings are selected'
  • Test the program..
  • Next
  • Yes, save these settings for this program

If you want to do, you can use The process explorer and add the column dpi aware to help you. This tools is avaible on the Microsoft sysinternals webiste.

Et voilà :)

This is the the explanation that you can find on the microsoft documentation

Windows® desktop apps fall broadly into two classes: apps that are DPI-aware and those that are not.

However, if an application is not DPI aware, and is running on a high DPI display, Windows scales the app by applying bitmap scaling to the application output. This ensures that the application is the correct size on a high DPI display. In most instances this will result in crisp and usable applications, but in some instances, the result is less crisp and might have a slightly fuzzy or blurry appearance because of the bitmap scaling.

You can try to use a different high-DPI compatibility setting for that app instead of the Let Windows try to fix apps so they’re not blurry setting.

  • Enter the name of the program in the search box on the taskbar,right-click the search result, and then select Open file location.
  • Right-click the program, select Properties, and then select the
  • Compatibility tab. click Change high DPI settings
  • Select Use this setting to fix scaling problems for this program… check box
  • Use I signed in to Windows option
  • Select the Override high DPI scaling behavior check box
  • Use Application option
  • Press OK and OK . Then Restart the program

Apart from all other solutions mentioned, the following worked for me:

Switch the external monitor (that shows blurry apps) as your main monitor'.

STEPS:

External Monitor Settings Windows 10

  • right click on desktop and click 'Display settings'
  • Select the external monitor and check the 'Make this my main monitor' checkbox

In case this helps anyone else, I experienced the same symptoms as rdhainaut driving a pair of Dell U2419H monitors from an XPS 15 (9560) laptop through a WD15 dock with single Display Port output and the second monitor chained to the first via DP.

The second monitor was blurred with migraine inducing vibration on the text.

Solution for me came through the Intel HD Graphics Control Panel which allows the refresh rate to be set for each monitor and importantly offers choices including 60i Hz and 60p Hz corresponding to interlaced and progressive.

My primary display was on progressive and the secondary on interlaced. Matching the setting for both displays resolved the blurred/vibrating text. Full process was

  1. rClick Desktop > Intel Graphics Settings
  2. Display > General
  3. Select Display > Digital Display
  4. Set Refresh Rate: Select 60p Hz

Repeat steps 3 and 3 for Digital Display2.

I had similar issue with a blurry screen when connecting in Windows 10 wirelessly to another laptop screen, extended mode.

The wireless display was scaled to 85% with an unnecessary black border around.

The issue was with the Intel Graphics Settings.

Steps to solve it:

  • Right click Desktop > Intel Graphics Settings
  • Display > Wireless Display
  • Picture Size <-- change to 100%

Had The same problem. I solved it by replacing the vga cable with an hdmi one.

In my case the point was that windows wasn't properly recognizing mi monitor aspect ratio, that actualy was 16:10 and, for this reason, it was only offering resolutions suitable for 16:9 displays.I figured this out setting the resolution to a value higher than the supported one, then monitor was asking for a 1920*1200 resolution while in the windows settings page there was only the wrong ratio 1920*1080. I also noticed that in this case windows wont mark none of the resolution available as the 'recommended'.
