      Avoid Overpriced HDMI Cables

      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.

      How does one review a cable?

      There was a time when cables of this sort were discussed only in hushed tones in the most sophisticated of Paris salons, where auteur theory challenged deconstructionism for epistemological primacy. Now, with the advent of wider accessibility, such cables have become commonplace in everyday homes and mundane discourse. What has been lost in the process, finally, is not the essence of cableness or cabletude, but rather something far more subtle -- that elusive je ne sais quoi that can only be called the conceptual distillation of connectivity. This paradox is fully on display in our kitchen, where an ordinary Apple TV box is connected to a run-of-the-mill television, while I sit and wonder why anyone would ask me to review an HDMI cable, or indeed how I should do it. What the hell: it's short. It's black. It's unobtrusive. It was cheap, and it works.

      These hdmi cables are just as good as the name brand cables. They perform just as good and they cost half if not less than the name brand cables. If you do a little bit of research you will learn that all cables have to be able to display the same amount of resolution to be considered hi def. So don't fall for the higher price and name brand hoopla. I have been using these cables since they started selling them so cheaply compared to the name brand cables. I used to only use name brand until I found out about the requirements for all cables and I tested several 60 plus dollar cables and then tried the dynex on the same bluray and high def tvs that run 1080p led and there was no difference that I could notice. Do yourself a favor and take a chance and try these cables and you will not be disappointed.

      Let's be clear: There ARE higher quality HDMI cables out there. However, unless you're going to be running an HDMI cable over a very long distance (25ft or more) or are afraid that even the slightest artifact will cause you to be beheaded by your "thinks he knows everything about everything" tech friend, this is all you need. Don't get suckered into thinking that you're not going to get the best picture possible unless you have 24K gold connectors and quadruple shielded wiring. None of those things are necessary for the average consumer. Believe me, you won't be able to tell the difference between this cable and a similar cable that sells for three to four times the price. Save your money and upgrade other things that actually matter.

      I bought this cable to hook up my Roku 3 to my TV at home. The guy at Best Buy told me that I should buy a more expensive cable for this if I wanted 1080P on my 55". I said no, I have used $200 cables and $10 cables and never noticed any difference ever unless it was on a PS4 in full HD. Which was very minor pixilation in a corner, which I can live with. So don't be fooled that a cheaper HDMI cable is not as good as a much more expensive one. Yes the build quality is not the same as Monster or the higher end ones, but for my purpose hooking up my Roku directly to the TV and not through a receiver it worked just fine.

      I work in the military, aerospace connector industry so any connector I buy gets a full examination. I have been shocked by the price of HDMI connectors and cables in the past. I am sorry but the technology of these connectors and cables do not justify their pricing. HDMI connectors are simple to manufacture and cheap. The price of this cable is reasonable. It works just fine without any problem. From a professional stand point the cable has three quality issues. The plastic molding surround the metal interface shell is a poor fit, the interface connect is sloppy, and the cable itself is very stiff. None of these issues effect the performance, unless you are going to be doing a lot of plugging and unplugging.

      In this age of technology, we have now officially switched over every TV in the house to a flat screen, HD TV. Our last prehistoric monster went out last year after many years of loyal service. I've bought several of these HDMI cables for connecting our FiOs boxes to the TV and our Netflix Rokus as well. It's so nice not to have to rely on those Red, Yellow, White AV cables anymore. The HDMI plugs into one port on each device and in no time flat you'll be enjoying clear, crisp picture with no muss, no fuss! It's been several months and we've had no issues with these cables and they're affordable, which is also a plus. The length is perfect for connecting most devices to the TV within a 4ft area.

      Barely acceptable audio quality

      This sound bar unfortunately has very poor sound. The sound can be adjusted slightly with three settings. These settings cause a small change in the equalization of the soundbar. But the high frequencies are lacking. This makes spoken language more difficult to hear. I use this with an LG 55" TV. You cannot use the speakers with the tv together with the soundbar; they are out of sync. So, overall, I cannot recommend this soundbar. Many of the other reviews strangely think the audio is great. I am not sure what they are comparing it to. It might be better than some cheap tv internal speakers. But for audio, this is very low quality.
