how to tell what kind of hdmi cable i have

If you've just bought a new 4K TV, y'all might exist wondering if you demand to buy a new HDMI cable to go with it. The very fast reply is: Probably non.

Hither's how to tell if the concluding call is a yep or a no.

HDMI cables explained

An HDMI cable is just a conduit between your Television and media device, be information technology a DVD, Blu-ray, or 4K UHD Blu-ray player; media streamer; video game console; or PC. Different types of HDMI cables exercise exist, merely their designations indicate how much data they can conduct. (Spoiler: There'southward really no such affair as a 4K HDMI cable.)

When pared downward to the nigh basic information, the video resolution guidelines—every bit set past the HDMI Forum Technical Working Group that defines the specification—are:

• Standard HDMI: Up to 720p or 1080i resolution at a 30Hz refresh charge per unit
• High Speed HDMI: Up to 4K resolution (including 1080p) at 30Hz
• Premium High Speed HDMI: Upward to 4K resolution with high dynamic range (HDR) at up to 60Hz
• Ultra High Speed HDMI: Upwardly to 10K resolution with HDR at a 120Hz refresh rate (4K video can refresh at upward to 240Hz)

The more than detailed versions of the guidelines matter if you desire more than just a basic Telly signal: If you play video games at more 30 frames per second, for example, or you lot intend to make full use of an HDR TV, or you want an HDMI cable that can also carry data over ethernet (most people do not, but that bandwidth can exist used for other things).

If yous attach a gaming PC capable of gaming at 4K/60fps to your Telly, you lot'll need an HDMI cable that can handle that level of data transmission.

For these types of scenarios, y'all must take refresh rate (measured in cycles per second, stated as Hertz, and abbreviated as Hz), the level of color precision (aka colour depth, measured in bits; e.yard., 8-bit, 10-bit, or 12-bit), and color information compression (i.east., chroma subsampling) into consideration. The higher you go with refresh rate and chip depth—and the less color information compression you lot opt for—the more data that will be pushed to your Television.

Appropriately, you lot'll demand an HDMI cable that has acceptable bandwidth. The chart beneath details the nuances that divide Standard HDI, Loftier Speed, Premium High Speed, and Ultra High Speed HDMI. A Premium High Speed HDMI cable should embrace the highest demands you lot'd inquire of a 4K Tv with a 60Hz refresh rate. If you bought a 4K Boob tube with a true 120Hz refresh charge per unit, similar for utilise with a PlayStation five or Xbox Series X, y'all should motion up to an Ultra High Speed HDMI cable.

(Note that the table refers to refresh charge per unit in frames per second: 60fps is synonymous with a display refresh rate of 60Hz, and and then on.)

If you've looked at the above nautical chart and realized that your plans require a Premium High Speed HDMI cable, don't blitz out to purchase i just all the same. Y'all might not need to spend whatsoever cash.

When to reuse an HDMI cablevision you already own

The HDMI cable that you already have might back up all the features yous need. Here's how to figure that out.

All you programme to practice is watch Tv and null further

But connect your Tv set and media device using your existing cable. If y'all get a steady image with no artifacts, you're proficient to go. No boosted thinking is required.

You lot want to watch HDR content, play games at 60 or 120fps, use a TV as a monitor, etc.

You can make up one's mind if your existing cable is adequate in one of two ways.

1. Cheque if the cablevision is labeled as High Speed, Premium High Speed, or Ultra High Speed. If your HDMI cable doesn't clearly specify what type it is, you might be able to wait it up if the manufacturer and office number are printed on the cord.
2. Plug the cable into your Boob tube and your media device, and so alter the settings on both to lucifer your requirements. If yous go a steady image while playing content, yous should be skillful to become.

Of the two methods, the second is a little more reliable—typically, you lot'll immediately get a signal (or you won't). But it's usually best to start with method one first so try method 2. If you finish up with a bare screen during method two, switching back to viewable settings can exist a hassle depending on your device.

You want to hide your HDMI cable within the wall

If you've hung your TV on the wall and at present want to run your cables inside the wall to keep them out of sight, yous likely won't be able to use an HDMI cable already on-hand. Professional installers utilise in-wall-rated HDMI cables for this purpose, and then should you if you're doing the work yourself: An in-wall-rated cablevision is made to resist fire (like during a ability surge or if something nearby is burning) and not give off toxic fume if it does burn.

For such cables, look for one of ii National Electrical Lawmaking (NEC) certifications: either Grade 2 or Class 3 (abbreviated equally CL2 and CL3). The divergence is in the maximum voltage that each must have: CL2 must accept up to 150 volts, while CL3 must have up to 300 volts. In both cases, the cable's jacket will as well be thicker and better insulated to protect the wires inside equally the cablevision is pulled through the wall and aptitude within tight spaces, such as a junction box. Either certification is sufficient for HDMI signals. In-wall rating should non add a meaning amount to the price of the cable.

Y'all need to send signals over a long altitude

If your source device is at ane end of the room and your display is at the other (such as a video projector and its screen), or if your source and display are in dissimilar rooms, you lot might need a cable with a congenital-in signal amplifier to ensure the data tin be transmitted from one end to the other. You'll commonly notice these cables classified every bit "active" HDMI cables (preface each of the cable types we've already discussed with "agile"). Another solution for long cable runs is an HDMI signal booster, such every bit the Cardinal Digital KD-HDFIX22.

Des Willie / Netflix

But want to sentinel Netflix shows (such equally The Crown) in 4K and nothing more than? If the HDMI cable you lot're using now provides a steady pic, yous're all set.

When to purchase a new HDMI cable for your 4K Television receiver

If the HDMI cablevision(s) you have on manus can't run across your requirements—say, playing 4K content at 120Hz or with HDR—and then you lot'll need to crush out for a new one. You can likewise buy a new cablevision if yous desire to ensure compliance with a particular HDMI spec. For example, Ultra High Speed HDMI cables must be certified to earn the label, and should thus have guaranteed compatiblity with HDMI 2.one devices like the PlayStation 5 and Xbox Series 10.

That doesn't mean you need to pay $30 or more for a cable (though agile cables do toll more). The price of the cable doesn't necessarily ensure operation. Rather, its classification and its certification exercise.

Which 4K HDMI cablevision should you buy?

You lot can purchase a very inexpensive cablevision and however go top-notch functioning. Our recommendation is to option from among Monoprice or AmazonBasics options, which have huge followings for their affordability and reliability. (See the sidebar for specific suggestions.) Active and/or exotic cables (e.g., cables that employ fiber optic strands instead of copper wires) for very specialized installations will toll more than, but they don't perform improve than their more plebeian counterparts in typical installations and manual distances.

If you lot don't know which exact cable to become, or yous'd like to peruse available options on your own, be sure to consider the following:

A high-quality cablevision needn't exist expensive. We tin can't stress this plenty, and information technology applies beyond the lath—including in-wall-rated cables.

Certified Premium High Speed HDMI cables have passed boosted testing in order to sport the label. (You tin can find out more about the certification and how to verify actuality of certification in this commodity.)

But you don't demand to pay a big markup to get that peace of mind: Monoprice, for example, sells two different 6-pes Certified Premium HDMI cablesRemove non-product link for slightly more $four each. And you tin buy a 15-foot, CL3-rated high-speed AmazonBasics HDMI cable for $11.

Best Purchase / IDG

These cables are extremely overpriced. There'south no need to spend that much on whatsoever passive HDMI cable, including in-wall-rated cables such as these.

Use keywords only as a starting point. If y'all look on Amazon or Monoprice.com, you'll sometimes see products with names like "Ultra Slim High Speed Cable." If you're not paying close attention, you might not realize this particular case is but a loftier-speed cable: The "ultra" in this case refers to how thin the cord is, not the speed at which it'southward capable of carrying information.

Ensure you get the right cable by looking at the actual specs. The quickest fashion to determine the blazon is to wait for its bandwidth rating.

• High Speed = 10.2Gbps
• Premium High Speed = 18Gbps
• Ultra High Speed = 48Gbps

Cost is still an important inkling about blazon and quality. Y'all won't observe a respectable Ultra High Speed HDMI cable for $3, but y'all tin find a skillful High Speed cable, although it might exist limited to a lower refresh rate. (Though these days, true Loftier Speed cables aren't as mutual.)

By paying attending to bandwidth rating, refresh rate, and price, you tin avoid unreliable cables. Options outside of the better-known cheap brands (AmazonBasics and Monoprice are currently the top two) can exist tempting, merely some upkeep cables have weak electromagnetic interference (EMI) shielding, which can disrupt your Wi-Fi network, and they might crusade visual artifacts and indicate driblet-outs. If you encounter a two-pack of High Speed HDMI cables for the same toll equally a single Monoprice or AmazonBasics option, go along with caution.

On the flip side, bandwidth rating and toll can also help you notice cables that punch above their weight, such every bit the AmazonBasics High Speed HDMI cablevisionRemove non-product link. It's not certified every bit a Premium High Speed cablevision, but the manufacturer promises it can deliver that much bandwidth (18Gbps). Unsurprisingly, it'due south also priced higher than a typical upkeep 6-pes High Speed HDMI cable ($7 vs $3).

Active HDMI cables should not cost exorbitantly more than their passive counterparts. While prices do go upward, you can find them for well below the usurious rates of highly marketed cables at Best Buy and similar stores. On Monoprice, for example, a vi-pes 4K Slim Loftier Speed HDMI cablevisionRemove not-product link costs $seven; its active counterpartRemove non-product link is priced at $28.

Purchase merely as much cable length as you need. The longer the distance that a signal needs to get, the more than probable that parts of that point won't accomplish its destination without amplification (e.g., an active cable or a point amplifier box).

The general rule of pollex is that for lengths of six feet or less, a passive cable is more than than adequate. Between half-dozen and virtually 25 feet is negotiable, and in a higher place that, most people will opt for an active cable or a bespeak amplifier.

Monoprice

Agile HDMI cables includes a signal booster to foreclose artifacts and drop-outs over long distances.

The receiving scrap in your Television can likewise influence whether or not a passive cable volition piece of work over long distances—if it'southward better at adjusting for a weaker signal, you won't need the signal heave.

Ignore nonsense features like aureate plating. Gold-plated connectors brand a marginal departure with analog signals, considering the connections don't oxidize, only they don't matter at all with the digital signals an HDMI cable carries. If you intendance about a solid motion-picture show, you lot only need to pay attention to a cable's speed rating and length, and whether it's passive or active. That's it.

HDMI cables vs. HDMI specifications

If you've heard of HDMI specifications (eastward.yard., HDMI 1.3, HDMI one.4, HDMI 2.0, and HDMI 2.i), you might wonder how HDMI cables relate to them.

As mentioned higher up, an HDMI cable is just a conduit for data to travel forth. You tin can think of information technology like a pathway: Cull a wider one (i.east., college bandwidth) if you have more information that must march forth it at the same time.

HDMI specifications outline what kinds of features are allowed to travel along that path: resolution, color depth, types of blush subsampling, and more. With each new specification, each new feature has increased HDMI'due south bandwidth requirement.

This table shows the features enabled with each version of HDMI.

Nosotros go into more than detail on the latest HDMI specifications in our HDMI 2.0 and HDMI 2.1 primers, only all you really need to know is which features your hardware supports and which features you intend to take advantage of. In one case you've narrowed that down, yous'll know which type of HDMI cable you need.
