If you plan on also buying an Ultra HD source, like a Roku , Ultra HD Blu-ray player or one of the new gaming consoles , chances are your current cables will also work with those. The best streaming devices , Blu-ray players and the latest versions of both gaming consoles can output 4K HDR. If your HDMI cables are just less than about 10 feet long, they'll probably work just fine.
If they're, longer you might have issues. Even if they worked fine with regular 4K, HDR is additional data and that might be too much for longer runs. Check all your other settings first however. Only a handful of TVs can actually accept that frame rate however. There are also only a few games that can run at 4K Most people won't have all those pieces, so their current cables will probably be fine.
If you have one of those consoles, and have a TV that supports 4K, and want to play one of the 4Kcapable games, and you need more than the single cable that comes with the console, then you should look into Ultra High Speed HDMI cables. Computers can send the maximum resolution and frame rate possible in the current HDMI spec. Noncertified cables might work, but it's less likely.
If the image on your TV is cutting out randomly or isn't showing up at all , this might be a cable issue. If none of your gear has changed, it might be a different problem, but maybe the HDMI cable is getting worn out likely if you plug and unplug all the time, or the cable is on the floor and gets trodden on. A new low-cost HDMI cable is at best a cheap fix, and at worst a cheap indicator that the problem is something else. On the other hand, if you've bought a new TV and it won't show the 4K or HDR content you send it, the cable might not be able to handle it.
A different, but still cheap, HDMI cable should do the trick. News Comments. Question If any drive other than Drive C: gets full, will it slow the whole pc? Question 10g - 2. Latest posts.

The one partial exception to the above is in the realm of resolution and color depth. Right now there are two regular testing tiers for HDMI cable and one optional tier.
The lower tier, "Standard" or "Category 1," certifies performance up to the bitrate required to convey conventional HD p or i video at standard color depth. Anything beyond that calls, at least in theory, for a "High Speed" or "Category 2" cable, which is tested to the Then there are "Premium HDMI Cable" certifications, where the testing is actually conducted out to 18 Gbps, to make sure the bandwidth really is there as it's supposed to be.
But at this writing December , there isn't even yet a compliance testing specification, so there are no Category 3 cables to be had. If someone says he's got one, ask to see a copy of the ATC certification; but don't expect to get a response, and hang on to your money.
Now, if you know you're running a "Category 1" cable but you have a "Category 2" need for bandwidth, do you need to worry, and do you need a new cable? Maybe, and we'll get to that in a moment. But quite possibly not. Before we get to that, there's another snake-oily problem to address.
We've been seeing a lot of cables that advertise various levels of stated "bandwidth. Surely THAT's got to be for real, hasn't it? We were, after all, just speaking about how bandwidth can be important. Well, bandwidth IS important. No question about that.
Shoving a few billion ones and zeros through a cable every second without error isn't as easy as some people think it is. But these stated bandwidth numbers don't mean anything -- nothing, zilch, nada. This one really seems to shock people -- after all, the number's on the package. Doesn't that mean the cable's been tested and has the bandwidth stated? Isn't that an electrically objective measurement?
To understand, let's back up a bit. What is "bandwidth"? In a cable, it's the ability to faithfully convey the signal over the frequency range where the spectrum of the signal falls.
Digital signals like HDMI video have interesting spectral properties -- they're very broad, so one can't just look at a single frequency, as we might when testing a radio antenna. If I said that a cable had resistance of one ohm at DC, we'd all know more or less what that means. And we could get an ohmmeter and measure it.
If we wanted to be precise, we could get a fancy ohmmeter that would check it down to the thousandth of an ohm accurately, and see just how close we came to the target. And resistance being a basic property of wire, we'd find that it's not that hard to achieve broad agreement among electrical engineers as to whether our wire came within an ohm, plus or minus some tolerance.
A good ohmmeter, properly calibrated, would satisfy everyone. But now that we've got the electrical engineers in the room, let's ask them a different question. Instead of a wire of which we want to know resistance, we present a data pair, like one of the pairs in an HDMI cable.
And we ask these electrical engineers: how much bandwidth does this data pair have? No matter how much test gear we have in the room, this question isn't answerable as stated. The engineers will ask us, in response: by what criteria are you judging bandwidth? Bandwidth, you see, is not a simple property like resistance. There is no single definition of it.
Instead, there are specifications for conveying data in accordance with various protocols, and these put the burden of conveying a signal, under the particular terms of the specification, upon sending circuits, cable, and receiving circuits.
