Review on Jabinco 20pcs Clip-on Ferrite Ring Core Noise Suppressor Cable Clip Set for Various Diameter Cables - Black by Rushabh Gonsales

I have a 10 inch portable LCD monitor that may flicker. I've replaced power cords, USB adapters, HDMI cables and adapters, everything I can think of and it still randomly turns off. Sometimes once a day, sometimes every few seconds! I thought it was some kind of interference so I bought them and plugged them into the power and HDMI cables and both ends on the monitor and USB-C. to the HDMI adapter. This seems to have fixed the issue as swiping is now very infrequent, maybe once or twice a month. I was really skeptical that these things would actually do anything, but I really think they help!
