If you have just opened one of your previous applications in your brand new computer with a very high-dpi monitor, perhaps you will find out that your interface that previously worked perfectly is now utterly broken and/or blurry.
This might be the case, for example, if you just tried to open an old Windows.Forms application in your brand new Surface Pro computer.
How to fix it
- Go the the Forms designer, then select your Form (by clicking at its title bar)
- Press F4 to open the Properties window, then locate the AutoScaleMode property
- Change it from Font (default) to Dpi.
Now, go to Program.cs (or the file where your Main method is located) and change it to look like

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
using System; using System.Collections.Generic; using System.Linq; using System.Windows.Forms; namespace Classification.BoW { static class Program { [STAThread] static void Main() { if (Environment.OSVersion.Version.Major >= 6) SetProcessDPIAware(); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MainForm()); } [System.Runtime.InteropServices.DllImport("user32.dll")] private static extern bool SetProcessDPIAware(); } } |
Save and compile. Now your form should look crispy again.
I encountered this problem while opening and editing Accord.NET sample applications in Visual Studio in a Surface 3 Pro.

Thank you very much, good sir!
Thanks a lot!! Great article!!!
Thanks much… everything looks so much better now!
This was a problem on my windows 8.1 box, and when I upgraded to 10, it was still an issue – blurry, and my controls were getting clipped/shrunken with lines of text cut in half and other weird artifacts that all looked fine in the designer. I checked the settings on my machine and yup, 150%. So I added the interop and changed the form AutoScaleMode to DPI as you recommended above, and >poof< like magic all the weirdness went away. Far far away!
Thank you so much, This worked in Visual Studio 2015 on Windows 10. I was having blurry fonts in all my forms!
For anyone interested in getting rid of blurry forms in VB.net:
– Find Application.Designer.vb (instead of Program.cs)
– Insert:
‘Inside Public Sub New(), AFTER the line MyBase.New(…
If (Environment.OSVersion.Version.Major >= 6) Then
SetProcessDPIAware()
End If
‘Outside of Public Sub New()
Private Shared Function SetProcessDPIAware() As Boolean
End Function
Cheers 🙂
Shit, it got rid of my line with System.Runtime.InteropServices.DllImport(“user32.dll”)
You need this inside pointy brackets or inequality signs () instead of quare brackets above the definition of SetProcessDPIAware() function
Thank you YumzLab, it actually worked awesomely!
Team,
I am having exactly the same problem as the link below and I have finally come to the conclusion that I had to implement the
SetProcessDPIAware() function on one of the windows forms encompassing the report viewer. I tried doing the changes to the application manifest file but it is not compatible with the Click Once Deployment technique.

After implementation, i found that there the font sizes have been minimized and there are some misalignment in other forms too.
Also I just want the report print layout to scaled to the width which is just one form. Is there any way I can just apply to this form and leave others untouched ?
Thanks a lot, and more than a lot …
it works on my Windows 10. See you on CP …
Cheers,
Thank you, works like a charm.
Fantastic! Thank you very, very much…
Thank you very much bro . You are best
Thank you so much ! So long i was searching for this !
Wonderful article, very useful and well explanation. Your post is extremely incredible. I will refer this to my candidates
You are a life saver!! Thanks a lot for this solution. Worked like a charm.
Thanks for this!! Solved the issue perfectly.
Great! It fixed my problem on Visual Studio 2015 and Windows 10. Thanks.
Thank you for explaining this solution! Works great with my C# Winform apps!
Most excellent!
very good :-0
Thanks !!!!!!!!
Blessed!! Many thanks.
It works !
Thanks,
Thank you!
That was rapidly driving me nuts!!
I think this is an informative post and knowledgeable. Thank you for sharing this wonderful post! I’m glad that I came across your article.
Thanks for sharing the informative concept. Your data visualization contents are really good. You will explain the concept is a very clear and detailed explanation.
Hello, thank you for the tutorial, very useful. I used these tips for fix de blurry Windows forms for my Visual Basic VB.net applications.
For fix in VB.net follow the steps:
–
1. In Program.vb insert the library:
Imports System.Runtime.InteropServices
–
2.Inside the subroutine Sub New, after the line MyBase.New, insert the conditional code:
If (Environment.OSVersion.Version.Major >= 6) Then
SetProcessDPIAware()
End If
–
3.Outside Public Sub New, on the next line insert the code:
Private Shared Function SetProcessDPIAware() As Boolean
End Function
Congratulations, you VB.net application is great for all DPI monitors 🙂
