"I went to Best Buy, Walmart"
Picked up a LG Oled c7 TV and it displayed snow on screen with the preinstalled 25' hdmi. I went to Best Buy, Walmart, and Target and tried 5 different cables. One of them was a 25' $99 hdmi cable. I was almost done with trying to fix the issue when the Birdie cable I ordered came in. Finally these freakin cables worked!! No snow with these high quality cables! The TV was one cable away from being returned. Great cables, make the purchase!
