Geoff set the position of "all HDMI cables are the same", but his position is not the only aspect of the story...
As you can see, there are many opinions about HDMI cables-some are for and against spending extra money on premium cables. In the long run, it is obviously worth investigating using a better cable, because even if the data packet "manufactured" the display device, your display device may not respond well to poor signals. It may be full of noise and other issues that may cause reliability problems. For shorter runs, your budget has a lot to do with what you should do. If your budget is really tight, spending an extra $100 on speakers may have a greater impact on performance than upgrading the critical HDMI cable. On the other hand, if you are using a high-end system, the price of a better shielded cable with a better connector is about US$75 to US$100, which started the discussion of advanced HDMI cables.

For those who are looking for more, more investment is needed. The important thing is not to become so mean that people who like to drink Aubert or Peter Michael make fun of Charles Shaw Chardonnay when they think they are good enough.
