To check which specific ports are HDMI 2.1, look for some mention of “4K@120fps.” Even TVs with only HDMI 2.1 ports should note the distinction.
To find the version of an HDMI port or cable, consult the device specifications from the Original Equipment Manufacturer. Different HDMI versions have been developed over the years, each version determining the capabilities and supported features of a configuration (limited by the lowest version port or cable).
Can I use the same cables and connectors? To take full advantage of the increased bandwidth of HDMI 2.1 and everything that comes with it, you'll have to use a new 2.1-compliant cable. However, the technology comes with the same connectors and has the same one-cable design as predecessor technologies.
The cable is backwards compatible and can be used with all existing HDMI devices.
HDMI 2.1 is backward compatible with HDMI 2.0. In terms of the functionalities, buying an HDMI 2.1 is a good choice to have enough capacity for data transmission, enjoy ultimate entertainment (if you already get a 4k/8k TV and video player), and also future-proof the 8K needs.
HDMI 2.1 cables will have the HDMI 2.1 logo on the packaging or on the cable itself. This logo looks like a capital “H” with the number “2.1” inside. If you don't see this logo, it's likely that the cable is not an HDMI 2.1 cable.
HDMI 2.1 allows for higher resolutions like 8K and higher frame rates of up to 120 frames per second (fps). Resolution improves the clarity and sharpness of the picture, which means you can simply see more details, and have less distance to the screen or a bigger screen without noticing any pixels.
We recommend most people stick to the HDMI 2.0a connections that are on current TVs. For higher bandwidth and advanced features, however, you will need to make sure that your HDMI cables match the format of the ports and devices you're using.
Yes, the HDMI port you use on your TV does matter.
If you have high-performance streaming requirements or want to benefit from features unique to a particular HDMI version, you must be selective about the HDMI port you use on your television.
All HDMI ports look the same, but don't have the same capabilities. While you can still pretty much assume that what you plug in will work, how it works is up for debate, and whether you're getting the absolute best out of your equipment depends on whether it all supports the highest level of the protocols.
No problem, it is about the same bandwidth requirements as 4k at 60Hz (and at 14Gbit/s for 1920*1080P@240Hz it is below the 14.4Gbit/s limit of HDMI 2.0 standard) so it will work just fine.
A 2.1 HDMI cable can be as long as 50 feet or over. As a cable with a higher frame rate, the greater the distance the signal has to travel, the more quality loss there will be. For the best length and definition balance, we wouldn't recommend going over 20 feet.
You're in luck — all you need is a single HDMI cable to connect your TV and soundbar enabled with Dolby Atmos (HDMI 2.0 for ARC should do the trick while HDMI 2.1 is necessary for eARC setups). This is the simplest option and will send audio directly from your TV to your soundbar.
Disconnect the HDMI cable from the HDMI port of each connected device. While the TV is ON and the device is ON, reconnect the devices one by one, waiting until the TV recognizes the device or go to the HDMI input where the device is connected and test if the TV is displaying a picture and if the sound is heard.
Sound devices and projectors all use this standard. For a better sound experience, you can use an HDMI cable to direct the sound from your Smart TV to sound device. ARC (Audio Return Channel) is a special function of HDMI high-speed certified cables via which the sound can also be sent back to the transmitter.
As long as you have at least HDMI 1.4, 120Hz is doable on your compatible TV or monitor. You can even do up to 144Hz if your display supports it.
Most HDMI cables are the same. What matters the most is the standards used in the connection ports on your devices. While there are different HDMI types, chances are that almost any cable will function for an average consumer's needs, with a few exceptions that are worth learning more about.
When it comes down to 4K TV, you do not need to pick up special HDMI cables. The HDMI cable standard can impact color and resolution, but newer versions are not required for 4K TV.
If your TV has the 3D feature it uses the 1.4 HDMI standard. All other TV's use the 1.3 HDMI standard.
HDMI connectors are available in three sizes: standard, mini and micro. There are also different types of HDMI cable (see the chart below). Not all cables use the logo but the cable specifications should indicate whether it is Standard, High Speed, Premium High Speed or Ultra High Speed.
4K (60p or 120p) content
Use a Premium High-Speed HDMI® cable which supports 18Gbps. Connect the HDMI cable to the 4K compatible HDMI port on the TV.
