HDMI v2.0 on HS-453DX

Just paid through the nose for HS-453DX - When connecting my LG high def TV to the HDMI v2.0 port with a HDMI v2.0 cable I get a 'no signal" message.
Connection to the HDMI v1.4 port works OK with the HDMI v2.0 cable.

I suspect that as the TV has a HDMI v1.? port and the TV is unable to handle the additional data.
Can anyone confirm my suspicion? OR Come up with a solution, other than buying a Ultra High Definition TV.

HDMI 2.0 Backwards Compatibility
HDMI Licensing is making sure that users are well-aware that HDMI 2.0 is built right on top of HDMI 1.x. Any device that has HDMI 2.0 will have already implemented HDMI 1.x. HDMI 2.0 also uses the same connectors, so you can continue to use the same cables and still make use of the higher speed, though there are some limits. For example, the higher bandwidth features of HDMI 2.0 like 4K resolution will require existing High Speed (Category 2) HDMI cables.

Wait Just a Second…
If you think that just because HDMI 2.0 claims to be backwards compatible with High Speed HDMI 1.3 cables, that it will work flawlessly—think again. What they really mean is that anything with HDMI 2.0 technology will operate any cables or devices with 1.3 technology. They also mean that at less than 3 meters, well, you may be good to go…but any longer and you definitely need to use an active HDMI cable. Active HDMI cables are cables with built-in chips that provide “EQ” at the input and output to reshape the signal at the end of a longer run. Certain companies, like Tributaries HDMI cables, are spec’d to have minimums that allow for the new 4K resolutions coming to market so that you don’t install a cable and get left in the dust two months later.

If you start to send 4K along a longer HDMI 1.3 cable, it is very likely that you’re going to find that your cables are no longer sufficient to handle the bandwidth. Even aftermarket EQ electronics and active HDMI 1.3 cables aren’t guaranteed to work. The real solution for very long runs is only going to be found with a new generation of active cables and the advancement of EQ found in televisions and source components. 4K at 60Hz can get upwards of 18Gbit/s which is considerably more bandwidth than what used to be transmitted along HDMI 1.3.

We’ll have to do our own field-testing of HDMI 2.0, however it’s going to take a while before a sufficient amount of products hit the market with the new technology. As soon as it does, however, you can count on us to give it a full shake-down.

article mentions 1.3, not sure about 1.4 but perhaps it's something similar to what is happening?

HDMI Version 1
HDMI Version was the first incarnation of HDMI and it underwent a number of revisions and updates.

-HDMI Version 1.0: As the name indicates, HDMI 1.0 was the first version of HDMI that was released. The release date was 9 December 2002, and it included the basic HDMI capabilities for a single cable digital audio/video connector interface. The format for HDMI Version 1.0 used the basic DVI concept but requiring audio and other ancillary data to be sent during the blanking intervals of the video stream. The version allowed for a maximum data rate of 4.95 Gbps per link.
-HDMI Version 1.1: HDMI 1.1 was released on 20 May 2004 and its main feature was that it added support for DVD-Audio.
-HDMI Version 1.2: HDMI 1.1 was released on 8 August 2005 and it broadened the appeal of HDMI. It added the option for One Bit Audio used on audio CDs and it removed the need that only explicitly stated formats could be used and added the ability for manufacturers to create vendor-specific formats
-HDMI Version 1.2a : The release data for this small update was 14 December 2005 and it added the provision for Consumer Electronic Control (CEC) features, command sets and CEC compliance tests.
-HDMI Version 1.3: HDMI 1.3 was released on June 22, 2006, and increased the maximum TMDS clock to 340 MHz providing a total maximum data rate of 10.2 Gbps. Like previous versions, HDMI Version 1.3 used 8b/10b encoding, to give it a maximum video bandwidth of 8.16 Gbit/s.
-HDMI Version 1.3a: This was a relatively minor update as indicated by the version number. It basically added a number of cable electrical updates to ensure that the cables operated totally reliably with the increased data speeds. It also added the optional ability to stream SACD in its bitstream DST format rather than uncompressed raw DSD.
-HDMI Version 1.4: This standard update was released on 28 May 2009 and HDMI 1.4 proved to be one of the major updates in terms of usability. HDMI 1.4 added support for 4096×2160 at 24 Hz, 3840×2160 at 24, 25, and 30 Hz, and 1920×1080 at 120 Hz. HDMI 1.4 also added an HDMI Ethernet Channel (HEC) to accommodate a 100 Mbit/s Ethernet connection between the two HDMI connected devices to enable an Internet sharing connection. It also introduced an audio return channel, 3D Over HDMI, and a new Micro HDMI Connector which was needed to equipment like camcorders that could not accommodate a large HDMI connector, but needed to interface with HDMI based equipment. HDMI 1.4 also provided for additional colours support.
-HDMI Version 1.4a: HDMI 1.4a was a relatively minor version update that was released on 4 March 2010. It focussed in improvements to 3D video technology and was delayed from being incorporated into HDMI 1.4 pending decisions that needed to be made by the broadcast industry.
-HDMI Version 1.4b: This version of HDMI 1.4 was released on 11 October 2011 and it included a number of minor changes. It was the last update provided by HDMI Licensing, LLC as future updates were taken over by the HDMI Forum, an industry body.

HDMI Version 2
HDMI 2 was the first update to be managed by the new HDMI Forum. In view of the fact that it was being managed by a different body, the version number was raised from 1 to 2 reflecting the major change.

-HDMI Version 2.0: HDMI 2 was released on 4 September 2013 and it was also referred to as HDMI UHD. The bandwidth was increased to 18 Gbps. It used 8b/10b encoding . HDMI 2.0 was suitable for UHD video at 60 Hz with 24 bit/px colour depth.
-HDMI Version 2.a : This minor update to HDMI 2.0 was released on 8 April 2015 and provided support for High Dynamic Range video with static metadata.
-HDMI Version 2.b : HDMI 2.0b added support for HDR video as described in CTA-861.G specification. This extended the static metadata signalling to include Hybrid Log-Gamma
-HDMI Version 2.1: This was launched on 28 November 2017 and added support for higher resolutions and refresh rates, including UHD 120 Hz and 8K 120 Hz. HDMI 2.1 also introduced a new HDMI cable category called 48G. This enabled cables to be certified to carry the new higher data rates.

HDMI is a standard that is evolving to meet the ever advancing needs of the audio / video industry. Since its first inception as HDMI Version 1.0, HDMI has advanced in terms of its support and capability. Now it is able to support the latest video standards whilst also incorporating many new functions and capabilities.

If I take an HDMI 2.0 cable and plug it into an HDMI 1.4 input/output port, will it still be able to run 4K at 60 fps or is it also dependent on the port?
Yes but it will work as HDMI 1.4. The ports have to be HDMI 2.0 to run 4k at 60fps.

Do I need to worry about compatibility between HDMI versions?
Only if you're working with components that use the latest HDMI version — currently 2.0b — and want to take advantage of certain features that are new to the latest spec. However, each new HDMI version is backwards compatible with older versions, so your older and newer HDMI-equipped components can generally still work together. So even if you use a 1.2 cable on 1.4 gear, or a 1.4 cable on 1.1 gear, you'll still get great picture and sound.
HDMI connection issues, solutions and workarounds
Different HDMI versions may cause some interoperability issues — for example, you generally won't be able to get HDMI 1.4 features with non-1.4 gear and cables. See our HDMI 1.4 questions below for more details.

Some problems are also caused by a manufacturer's improper or incomplete implementation of the technology. Some incompatibilities in the digital "handshake" of the HDCP copy-protection code still exist between HDMI-connected components, especially when routed through an HDMI-equipped home theater receiver.

Whenever problems like these are discovered, the HDMI standards group contacts the manufacturer and requires that the issue be resolved. In some cases, products have been recalled.

Beyond the initial handshake, there are other possibilities for miscommunication between components. At the beginning of the article, I mentioned that HDMI supports two-way communication between a video source and a TV.

Part of that digital conversation is known as "EDID" (Extended Display Identification Data), which describes the TV's capabilities to the source component. EDID info typically includes the manufacturer name, product type, screen resolution, and color depth. Thanks to EDID, two devices can not only talk to each other, they'll actually know whom they're talking to. And that makes auto-configuration possible, which simplifies your setup process.

Keeping all that in mind, here are some of the most common HDMI connectivity issues we've heard about from customers, along with possible solutions or workarounds:

not quite sure what you want to achieve ...connect it so it works ..problem solved

well .until you discover that qnap devices are mediocre to bad playback devices

an external player would be much better
