It happens that NDI does not work due to different versions included with the software.

You can fix this by installing the latest version of NDI Tools and copying the latest DLL libraries from there:
At the address:
..\Program Files\NewTek\NDI 4 Tools\Runtime\

Processing.NDI.Lib.x64.dll (for 64-bit systems)

Processing.NDI.Lib.x86.dll (for 32-bit systems)

Paths of popular programs where to copy fresh DLLs:
..\Program Files\Resolume Arena\
..\Program Files\Derivative\Touch Designer\bin\
..\Program Files (x86)\vMix\ndi\x64\ 
..\Program Files (x86)\vMix\ndi\x86\

Here’s the checklist to start with:

1. Which video output is the control monitor connected to?
   It should be connected to your dedicated graphics card.
   
2. Which graphics card is rendering?
   It should be your main dedicated graphics card.
   You can check this under: Output -> Show Display Info, the details will appear in the top left corner of the screen.
   
3. What is the video codec of the clip (e.g., mov dxv3 @25)?
   It is highly recommended to use the native DXV3 codec.
   Technically, you can use H.264, MJPEG, HAP, ProRes, but stable performance is only guaranteed with DXV3.
   
4. What is the frame rate of the video clip (frames per second)?
   Refer to the last point.
   
5. What FPS is set in the project settings?
   Refer to the last point.
   
6. What is the signal format being received (if a capture card is used)?
   Refer to the last point.
   
7. What frequency is set on the video card outputs (e.g., 50Hz)?
   Refer to the last point.
   
8. What frequency is set on the control monitor (e.g., 50Hz)?

From points 4 to 8, all frequencies and frame rates should be divisible by a common denominator!

• Frame rate of the video clip.
• Frame rate in the project settings.
• Frequency of the input signal on the capture card.
• Frequency on the video card outputs (monitors/displays/processors/sending cards).
• Frequency on the control monitor.

All these points are crucial!

EXAMPLE:
If you are using cameras that operate at 1080p @50, then all the points listed above should be divisible by 50Hz. Monitors should be set to 50Hz, content should be at 50 and 25 fps accordingly.

If you find yourself in situations where you accidentally hover your mouse over a minimized window icon on the Windows taskbar, and suddenly the screen briefly displays a browser window or an open folder instead of your footage from Resolume, it’s likely that Aero Peek is enabled.

This beautiful feature, aimed at enhancing the convenience of working with Windows, becomes a major issue in our field, causing significant frustration for video engineers, VJs, and directors.

Disabling Aero Peek via System Properties

• Go to System in your system Control Panel and press the Advanced System Settings
  Or you can use the shortcut:
  Press the Windows + R keyboard shortcut to open the Run dialog, then type sysdm.cpl and hit Enter.
• On the System Properties dialog box, select the Advanced tab. Click the Settings button under the Performance section.
• Select the Visual Effects tab, look for the option entitled “Enable Aero Peek” or “Enable Peek“, which allows you to turn the Aero Peek feature on or off.
• Click Apply
