If your camera view looks split in half with the left half on the right side and the right half on the left side this is due to the Windows Magnification is too high. This is usually only the case when you are in a higher desktop resolution like 1920x1080.
The easiest way to fix this is to right click on the DF-Camera Desktop Icon and select Properties.
Then Select the Compatibility Tab.
Then check the box next to Disable display scaling on high DPI settings.
Click Apply and then click Ok to close the window. Now you can run the DF-Camera and the issue should be corrected and the camera image should look correct.
