I can understand how a USB cable will improve the sound, but when it comes to how HDMI cable can improve the picture quality, I am not quite there yet.
Can anyone describe the engineering behind how HDMI cable would improve the picture quality?
First in order to study the difference, you have to first understand the fundamental transmission of the data in the HDMI cable. The article didn't do that. Until you understand the basics, you can't perform any test.
