LabVIEW Graphics Looks Blurry After Changing Windows DPI Scaling

Issue Details

I am using LabVIEW and changed the Windows DPI scaling setting to 150% to improve readability on my monitor. After launching LabVIEW, I notice that the graphics and text appear blurry instead of sharp. This behavior occurs consistently when DPI scaling is enabled.
  • Why is this happening?

Solution

This behavior occurs because LabVIEW uses bitmap-based rendering for certain UI elements. When Windows applies DPI scaling to applications that are not fully DPI-aware, it stretches the bitmap image, which results in reduced clarity. To improve the appearance of text and graphics, configure Windows to handle DPI scaling differently:
 
  1. Locate the LabVIEW executable:
    • For 32-bit environment:
      C:\Program Files (x86)\National Instruments\<YourLabVIEWVersion>\LabVIEW.exe
    • For 64-bit environment:
      C:\Program Files\National Instruments\<YourLabVIEWVersion>\LabVIEW.exe
  1. Right-click LabVIEW.exe and select Properties.


 

  1. Navigate to the Compatibility tab.
  2. Click Change High DPI settings.


 

  1. In the new window:
    • Enable Override high DPI scaling behavior.
    • Set Scaling performed by to System (Enhanced).

  1. Click OK, then click Apply.
  2. Restart LabVIEW to apply the changes.

Additional Information

Bitmap images are composed of individual pixels. When scaled, these pixels are enlarged, which can introduce visible artifacts and blurriness. In contrast, vector-based graphics are resolution-independent and scale without loss of clarity.
 
Windows DPI scaling attempts to improve readability on high-resolution displays. When an application is not fully DPI-aware, the operating system compensates by scaling the rendered output, which may degrade visual quality.
