HDMI Cable


#1

I bought an HDMI cable (to connect my laptop with an LCD I bought: ASUS MS 228H) from Sassi Arcade, Clifton for Rs.550.

I wanted to know what are the two things which are highlited in red circles:

As most HDMI cables that I found on the internet do not have these:

What are those two things for? Their purpose? Does it make any difference?

Is there any need to change the cable?

These are ferrite beads , this has something to do with current loss. Someone in Electircal engineering might be able to explain it better.
