Review on 🔌 Cable Matters HDMI Keystone Jack Pigtail Cable - 2-Pack, 8 inches, Black by Andres Callahan

I dared to connect the built-in HDMI cable to my LG CX TV. Although they transmit a 4K signal, there is significant artifacting (white dots that look like stars) in areas of the screen that should otherwise be either black or showing content. Removing the Cable Matters adapter and connecting the TV directly to the video source fixed the problem immediately. This will likely work for 1080p or other less intense graphics, but stay away if you're trying to use 4K HDR.
