No. There are several different types (or "categories") of HDMI cables, rated by bandwidth. This is not the same as an "HDMI version". The HDMI cable category certifies that the cable can handle a certain amount of bandwidth. Higher resolutions and higher refresh rates increase the bandwidth required for video transmission, so for high-bandwidth formats like 4K 60 Hz not all HDMI cables will function properly. All other features* of all HDMI versions do not depend on the cable to "support it". Features like HDR, audio, ARC, 3D, variable refresh, and anything else will work on any cable. HDMI 2.0 features do not require a so-called "HDMI 2.0 cable" rated for 18 Gbit/s, which is why they are not called "HDMI 2.0 cables" in the first place, they are called Premium High Speed HDMI cables (as listed in the table below). The only thing that requires these cables is high-bandwidth video like 4K 60 Hz. The cable does not affect support for any other feature of any HDMI version. (*The only exception to this is inline Ethernet, which does require a special "HDMI with Ethernet" cable.)

Unfortunately it still can. Support for the full bandwidth is not a requirement for a device or control chip to be HDMI 1.4a-compliant. Very few displays (certainly during the peak years of HDMI 1.3/1.4) have specs that can even use the full bandwidth, so it wouldn't make sense to require that all devices wishing to implement any HDMI 1.4 features must use a more expensive control chip capable of the full bandwidth, when virtually none of them have any use for it.

+ Isn't the extra bandwidth in 1.4 only used for 3D at 60 Hz per eye, not for normal 120 Hz video?
- No. This is something that people often repeat for some reason, that although HDMI 1.4 has over twice as much bandwidth as 1080p 60 Hz requires, that extra bandwidth is apparently only allowed to be used for 3D frame packing. While it is true that 3D is one of the uses for the extra bandwidth, there is no restriction on using it for other purposes, such as standard video transmission at higher resolutions and refresh frequencies. This claim that the extra bandwidth is only allowed to be used for 3D is a bit of a head scratcher when you consider that the bandwidth increase has been there since HDMI 1.3, but the 3D format definitions (such as frame packing) weren't added until HDMI 1.4.

Speaking as someone who has read the actual HDMI 1.4/a/b Specification documents, this claim of 1080p 120 Hz support being introduced in HDMI 1.4b is completely false.

Nothing was introduced in HDMI 1.4b (see here), simply minor edits, which is why you don't generally see "HDMI 1.4b" devices, because technologically it is identical to HDMI 1.4a, just some changes to the wording in the HDMI Specification document.
- 1080p 120 Hz has been explicitly listed in the HDMI Specification as a supported format since HDMI 1.4 (not just 1.4b), but even under HDMI 1.3 or 1.3a it can be implemented as a vendor-specific format which is a perfectly valid approach. Video formats do not require "support" from the HDMI Specification to work, because the word "support" does not mean what most people think it means in this case.
+ 1080p 120 Hz has been explicitly listed in the HDMI Specification as a supported format since HDMI 1.4 ( §6.3.2), not 1.4b, but even prior to that in HDMI 1.3 or 1.3a it can be implemented as a vendor-specific format which is a perfectly valid approach. Video formats do not require "support" from the HDMI Specification to work, because the word "support" does not mean what most people think it means in this case.
When the HDMI Specification "adds support" for a certain format, it doesn't mean it in the conventional sense of "adding the capability" as if it wasn't previously possible. They mean it in a more literal sense of adding supporting material to help strengthen it, by defining standardized timings for the format to help with compatibility and ease of implementation instead of leaving it purely to the vendor's discretion.
+
+ This "support" isn't actually necessary to display a format though. Even if a format isn't supported by the HDMI Specification, it can still be displayed through HDMI. 2560×1440 for example is not listed in the HDMI Specification either, so it is just as "unsupported" by HDMI as 1080p 144 Hz is, and yet it's implemented over HDMI on hundreds of different monitors. The same can be done with 1080p 144 Hz if manufacturers choose to do so.
- A more obvious example of this usage of the term "support" is ultrawide formats; HDMI 2.0 "added support" for the 21:9 ratio, even though ultrawide resolutions were available before HDMI 2.0 even existed and were working just fine over HDMI 1.4a. "Adding support" for 21:9 just meant the HDMI 2.0 spec added material to help establish standardized formats and timings, not that 21:9 formats weren't possible in previous versions, and indeed the majority of ultrawide monitors use HDMI 1.4a even though it "doesn't support" 21:9 ratio formats.

"Any video format timing". Am I just taking it out of context and applying it beyond its intended meaning? No. Here's the same section from HDMI 1.1:
- In HDMI 1.0 and 1.1, only certain pre-defined formats were allowed (listed in §6.1–6.3; all of them are 60 Hz and under, so HDMI was indirectly limited to 60 Hz by that). In 2005 with the release of HDMI 1.2, that clause was specifically changed to say what it still says today, that any format is allowed. It's quite deliberate.

In 2005 with the release of HDMI 1.2, that clause was specifically changed to say what it still says today, that any format is allowed. It's quite deliberate.
HDMI 1.2 was designed to make HDMI more viable for the PC space, by allowing any arbitrary resolution and refresh rate (within the bandwidth limit), as opposed to the strict adherence to only standardized home theater formats required by HDMI 1.0 and 1.1. Although it does still have a list of pre-defined formats (to maximize interoperability between products, as it says), any format which is not explicitly defined in the HDMI Specification may still be implemented as a vendor-specific format.
HDMI 1.2 also expanded the list of explicitly defined formats itself to include some >60 Hz formats like 720p 120 Hz, so the claim that it or later versions of HDMI impose a flat 60 Hz limit is pure nonsense.
