Poor video and sound quality when connected by HDMI
When your TV has no picture, no sound, intermittent sound drop, or intermittent picture noise, and you're watching something from a device connected by an HDMI cable, one of the simplest potential causes of the issue is that the cable is low quality. Since replacing the cable with a higher quality one isn't always easy or convenient, Samsung 2019 Smart TV models have a setting that can be used to to adjust how the TV interprets the HDMI signal and improve compatibility with the cable.
