Have you heard? Netflix's award-winning drama House of Cards is back next month! Not only that, but it'll be one of the first shows ever to be available in Ultra HD. Great, right? Wait, what is Ultra HD?

Well, we might as well have this conversation sooner rather than later because you're going to be hearing a lot about Ultra HD this year. Fact is, you might have already heard about Ultra HD and not even known it. Ultra HD or as it's more commonly known, 4K, is the new 3D, in that 3D was the new Full HD, and so on.

But up until this point, the money you would have put towards a 4K TV could have gotten you two Fiat 500s. And with the annual Consumer Electronics Show going on in Vegas this week, it's only going to get worse (better?) as the year goes on and UHD sets from the likes of Samsung, Sony and Vizio start to roll out.

What you really need to know about Ultra HD or 4K is that UHD TVs display quadruple the image quality and double the resolution of current Full HD (1080p) TVs. If you thought porn in Full HD was unnecessary, then you're going to run screaming in the other direction when you see that razor burn at 4,000 pixels. You'd have to stick your face right up against the screen to even see the pixels.

What's more, these 4K TVs are huge. Most are in the 50- to 120-inch range. Because why would you want a tiny a 3840 x 2160 resolution TV? While the cost of one of these new 4K TVs won't be in the $20,000 and up range, though some will be, don't expect them to be a couple thousand dollars either. At least not for one you should actually buy.

Besides price, what you really need to know is that there just isn't a whole heck of a lot of 4K content out there. Sure, Netflix will start streaming House of Cards and other upcoming original shows in 4K, but maybe you don't subscribe to Netflix or care for its shows. Then what? Exactly. Netflix CEO Reed Hastings has said in the past that 4K streams will only need 15mbps to work properly, but who really knows.

Ultra HD 4K TVs aren't gimmicky the way 3D TVs were considering TV shows and movies are shot in 4K anyway. But unless you're sitting on a pile of money and only care to watch House of Cards over and over again, we'd suggest you wait on picking up a 4K TV for the foreseeable future.
