This article will guide you to use some tricks when using Karaoke HiFi
Change resolution:
The default resolution when running Karaoke HiFi is 640×480. Higher resolution is not recommended for the smooth of visualization & cdg performance. However, you can change this default resolution by adding parameters to the shortcut of Kar2Fi as following:
“X:\Prrogram Files\Karaoke HiFi\Kar2Fi.exe” 800 600
or
“X:\Prrogram Files\Karaoke HiFi\Kar2Fi.exe” 1024 768
(X is the drive where karaoke hifi is installed)
Use slideshow as background karaoke
Enter to the Video Playlist screen, select “Add File”, inside the box “File Of Type”, select “All Files”, browse to the folder that stores your photos and choose those you like or all by pressing “Ctl+A”. Exit the Video Playist screen and press F9 to switch to Slideshow Background. Now it’s time to enjoy your perfect slideshow

Don’t use visualization as karaoke background, use video / slideshow instead.
