If you want to connect a device to your HD TV, this Dynex HDMI Cable does the job at a fraction of the cost of overpriced "premium" HDMI cables.
You may not or may care to know that I have a BS in electrical engineering and currently work with advanced digital communication systems for transmitting data between devices. Thus, I could go into technical details, but I won't. All I'll say is that there is no difference between cables based on price and based on the evidence I have seen. For example, based on compliance with HDMI standards, there should be no discernible difference between cables. Blind studies have supported this finding.
Pretty much, a cable will work or it won't. Make sure you get a cable rated for your desired speed in that you should have a higher speed rated cable for more intensive data rates, such as for 3D video. All cables will support Blu-Ray-type speeds. The main possible difference between premium and normal HDMI cables may be based on structural quality, which would come into play if you are wiggling the cable a lot, such as when mucking around behind your TV a lot. However, even the most expensive cables would fail with enough bending and twisting.
At one point, I was encouraged to get a more expensive cable at a high end A/V shop, which I did because I wanted to get a component up and running and the shop only had the expensive cables. Once I got a less expensive cable, I did not notice any difference and returned the overpriced cable.
People may debate the difference between cables based on price. However, I am in the camp that either a HDMI cable will work or it won't and there should be no discernible difference. This is my opinion and you are welcome to it for free.
Hope this review helped you for whatever reason you may have read it.
