What type of HDMI I have?

[peibolrz]

I have an HDMI and I wonder what type is it, 1.4, 2.0 or 2.1.

How can I physically know? Can I see it with the pc?

Thanks

Is it the HDMI port on the mobo or your GPU?

You'd need to check the specs on your GPU or motherboard. There is no physical difference between HDMI 1.4 and 2.0 (not sure on 2.1, but I believe it is still the same. It won't be 2.1 though). The revisions are controller upgrades that improve the signalling efficiency, so there's no physical signs really. 

 

What GPU/motherboard do you have?

I have a 1070 armor oc and a b350 plus

Your GPU has HDMI 2.0 and the motherboard is HDMI 1.4b

how do you know?

Well, I knew the 1070 has HDMI 2.0, but it's in the specifications for the GPU and the motherboard.

HDMI 2.1 isn't available to consumers yet. It will be backwards compatible, so HDMI 2.0 (and 1.4) will work with HDMI 2.1 devices, but only features of the lowest version would be available. So if you got a monitor with HDMI 2.1, your GPU would work up to HDMI 2.0 specifications and your motherboard would be able to do HDMI 1.4 specification. 

 

In order to get full HDMI 2.1 support, you'd need a new GPU as the HDMI version cannot be upgraded on its own. For some of the high bandwidth specs such as 8K@60 and 4K@120 supported by HDMI 2.1, you'd need a new 48G cable. The cable will be backwards compatible as well, as the actual connector is still the same. 

 

HDMI.org have a good FAQ on HDMI 2.1 if you're interested http://www.hdmi.org/manufacturer/hdmi_2_1/

@Oshino Shinobu thanks a lot appreciate it , but if I have for example in one hand a hdmi 1.4 cable and in the other a hdmi 2.0 how I notice the physical difference? is there any difference?

HDMI version does not apply to cables. It only applies to the end devices. You can use an HDMI 1.0 cable to carry an HDMI 2.0 signal, provided the 1.0 cable was built well enough.

 

The only thing a version tacked on a cable means is it's been certified to meet that version's standard. Nothing more.

HDMI 2.0 cables and 1.4 cables are exactly the same.

 

There'sa "HDMI Premium High Speed Cable" certification that holds the cables to a higher quality to ensure that the cable will perform optimally for HDMI 2.0, but in most cases where you're doing a short run and there's not a ton of electrical noise an "HDMI High Speed" cable ('HDMI 1.4' cable) will work for HDMI 2.0

 

HDMI 2.1 requires completely different cables, but they should be clearly labelled. HDMI 2.1 cables will work with HDMI 2.0 and lower, but to get HDMI 2.1 speeds you *will* need specialized cables.

 

There's 3 different speeds of HDMI cables. Standard speed that only really work with HDMI 1.0, High Speed which works with any version up to 2.0 (the vast vast vast majority of cables you find are high speed), and Superspeed/2.1 which work with any version up to 2.1

There is no such thing as a HDMI 1.4 or 2.0 cable. There are Category 1 and Category 2 (hi speed) cables. Category 1 cables can only go up to 1080i. They're very uncommon now days. Category 2 cables can do all current HDMI revisions, including HDMI 2.0. They will also work with HDMI 2.1, but some of the high bandwidth features of HDMI 2.1 will need a new 48G cable.
