Interesting, but could this damage the monitor in some way if used long time?

no

It should not do any damage. It probably puts different display patterns on the screen that concentrate the EMI radiation at one frequency in the AM broadcast band. It probably varies the pattern so that the amplitude of the radiation varies with the audio level. I suspect that it has high audio distortion, but the specifications for AM broadcast transmitters is 5% distortion.

I guess this program should be more practical for the CRT monitors instead of the LCD. I havent tried yet. Did anyone try this program?
