    I've always wondered wether you get better picture with an expensive cable or not ?

    Thanks

    It's digital. It either carries the signal error free or it doesn't (and you get perfectly good error-free cables for around a tenner). Other than build quality, there's little to be gained from spending more.

    I would add, in the days of analogue signals, it was worth spending a little more on s-video and scart cables.

    Agreed. The picture quality will not be affected. Some cables might not be capable of running a reliable signal though, so you might get drop outs or sparkles.... But this will be pretty evident from the get go. So long as you buy cables that are suitable for your equipment (e.g. hdmi 2 for any HDR equipment), there's very little point getting over priced cables.

    The only time I'd say you might want to spend a little more, is if you plan on connecting and disconnecting things often (if for example you often take a games console to a friend's house or something).

    This comes down to the affore mentioned build quality.

    But even then, be careful not to fall for marketing blurb.

    Just choose a cable that is suitable for the equipment, the correct length, and doesn't look like it's going to fall apart after a week :)

    Quite often, an HDMI cables cost does not relate to its build quality!

    Poorly constructed HDMI leads can cause big issues. Which is why it's highly recommended that you use nothing but Premium certified HDMI leads, especially between any device that supports HDR.

    All genuine 'Premium Certified' products will display a hologram on their advertising and on their packaging to prevent counterfeiting: -

    [​IMG]

    For more information why your HDMI leads need to be 'Premium' certified look here: HDMI :: Premium HDMI Cable Certification Program :: FAQs

    Plus, genuine Premium certified leads (with hologram) are not expensive! See below for some examples: -

    [​IMG]
    [​IMG]
    [​IMG]

    Suffice to say, when passing high bandwidth signals at up-to 18Gbps (with features such as: 4K UHD at up-to 60Hz with BT.2020 colour space and HDR-10/HLG), it's most important that any intermediate HDMI switch-gear in your connection chain also supports such bandwidths and features.


    Cheers

    HDMI v2.0b, like previous HDMI versions, sets out a specification of proposed/supported features. Which means it's up-to device manufactures to decide whether or not such features are integrated into their products.

    Just-so-you-know... the NOW TV service currently offers 720p video (at up-to 4865Kbps) and stereo audio when accessing NOW TV content. Which means there's no requirement for the NOW TV boxes to support anything higher than HDMI v1.3.

    Fair enough. HDMi 2.0b is backwards compatible right ?

    The HDMI v2.0a/b connection supports all previous HDMI versions features.

    Out of interest, what will you be using your NOW TV box for?

    If your intention is to view football via Sky Sports, you could do this by accessing the LG televisions in-built NOW TV app!

    Sorry for the confusion. I have two TV's, one is a smart TV which as you rightly pointed out can do NowTV internally. The other is an old school plasma which requires a box

    I bought the lg sj9 soundbar last week. Ordered a new hdmi cable for £30, apparently it is hdmi 2.1 and can display 10k or 4k 120hz. I know kinda pointless just now. Big question, real or fake? No reviews etc. Will test it on my xbox one x + forza 7. That is as high as i go for testing.

    If it is legit, should i plug the new cable into xbox - soundbar, then xbox cable, soundbar to tv.

    The xbox is extremely hit or miss weather it will display picture or sound when I launch the console, or any game. When I have a black screen, pressing guide then a, will take me back to the home screen where I can get picture and try again, same with no sound, go back to dashboard and rejoin game. I hope the new cable will sort this out.

    Its not officially certified.
    It cant be as the official 48G or Ultra testing program is not ready yet.
    It wont be ready until the end of the year and it will probably take another couple of months into 2019 for Authorised Test Centres to upgrade their gear and upskill their staff.
    This is only the second one Ive seen, the first fake was the Belkin one being pushed with the Apple TV 4K

    CE Devices With Certified HDMI 2.1 Unlikely This Year

    When genuine 48g cables show up, they will carry the official logo and almost certainly carry a hologram sticker.

    HDMI :: Manufacturer :: HDMI 1.4 :: Finding the Right Cable

    Youve bought from a seller who has most likely used a premium cable, called it 48G, and stuck an extra 25 quid on the price tag.
    Expect to see that a lot until items carrying the official logo show up in early 2019 sometime.

    That's what I am thinking about the cable, its a bit early for hdmi 2.1. As long as it plays forza 7 on my xbox one x, 4k @ 60 fps I will be happyish, no way for me to test beyond that. If it doesn't, it will be getting returned. Beyond my xbox one x I think all my hdmi cables are from the xbox 360 era, probably all hdmi 1.4.

    This cable is just to plug in from soundbar to tv, lg c6, think the ports are only 2.0a on the tv.

    If there is any official packaging with the cable I will post up a picture. Its sitting at a amazon locker just now, will pick it up on my way to work.

    Edit - Mind you is the xbox one x not a hdmi 2.1 cable. I always thought that the X was hdmi 2.0b, which can can do VRR etc. I never heard them give a straight answer on that.

    You shouldn't be happy, you've been ripped off.
    You could've gotten what you need for less than a tenner and certified to boot.

    https://www.amazon.co.uk/OMARS®-Pre...TF8&qid=1534967141&sr=8-3&keywords=Omars+hdmi

    I,d return it, get the genuine article, spend the savings elsewhere.

    I think you guys are just jealous that I have a 10k cable, lol. I chose the cable and I wasn't that bothered by the price. Now I have to go and test it.

    The only “ official “ logo on the box is the high speed logo, not the “ ultra “ logo that all 48g cables will have when they show up.
    See here....
    HDMI :: Manufacturer :: HDMI 1.4 :: Finding the Right Cable

    Definitely a con job.

    Also, and for the benefit of everyone else, HDMI numbers do not refer to cables, only to chipsets, cables are rated in terms of bandwidth and can be standard, high, premium, or Ultra speed.
    Mentioning hdmi version numbers in relation to cables is forbidden under hdmi.org rules so even that high speed logo is suspect.

    Oh dear smcbeath,

    As mentioned before, all genuine 'Premium Certified' HDMI leads will display a hologram (as below) on their packaging and their advertising: -

    [​IMG]

    Sadly the product you have purchased does not display the hologram, which means there's no way to establish how it's been designed, manufactured and tested. And therefore, there's no way to establish how they can support any of their claims!

    Send it back and buy a genuine 'Premium Certified' HDMI lead....

    I would not recommend this cable to anyone.
    They are extremely difficult to disconnect from the devices and mine are stored away as it was a pain to disconnect from my TV. This will end up damaging your devices!!!!!

    Dimensions of the physical connector are tightly controlled by the cable spec.
    If its out, get a replacement.
    Its always a possibility that a plug or port is damaged.

    These cables are certified and traceable via the barcode, so definitely better than most.

    How odd... I currently have three of those 'Premium Certified' OMARS HDMI leads and don't have any problems with them!

    That being said. I'd be interested to know why you have to regularly disconnect the HDMI leads from the back of your TV...

    I could see somebody doing that with a laptop, but if it were me I'd leave the HDMI cable plugged into the TV and coil the laptop end neatly.

    There are a few people on AVF who really know HDMI, it is worth listening to them.

    Indeed. Of which andy1249 is probably at the top.

    So much wasted money on HDMI cables.

    So I tried my hdmi cable via xbox one x direct to tv and it works fine with 4k and hdr. Still have the same issue when connecting, xbox - soundbar (sj9) - tv. Forza loads with no picture but will have sound. Going back and fore to dashboard will eventually fix it. Might take 3 to 4 attempts to get both picture and sound.

    And to you guys, £30 on a hdmi cable isn't a lot compared to what I have spent on tv, soundbar, xbox etc, plus I love braided cables. Yep I probably could have got one of those cheaper as well.

    When I buy a 8k tv I will be back to tell you lot how it doesn't work etc:D :facepalm:

    Wait, you're going through your soundbar? And it works when going direct to your TV? Therein lies your problem.

    You definitely wasted money on a new cable.

    Well, I don't know the reason, what I can say for a fact is that they are extremely hard to disconnect from the 3 TV I tested. Not just 1, 3. And 2 of these were brand new TV's.
    Damage HDMI ports is ruled out of the equation.

    Confronted the seller but never got a reply, so, I think this says the rest...

    Also, if you ready the reviews, especially the 1 star reviews, you will find this to be a common issue.
    I have several HDMI cables but these OMAR ones have some sort of "hooks/claws" on top of the connector and this is what is causing the issue.
    I have never seen any other cable with these sort of "hooks/claws" which are pretty much useless and is more cause of a problem than anything else.

    My other cables are not certified and I dont see any difference at all in the image quality or anything else.
    So, based on my personal experience NO! DO NOT BUY THESE CABLES just because you are thinking you are buying something better. Is just plain bollocks.

    Can you post a picture?
    The plug should not have anything that is not in the drawing attached.
    The drawing is from the spec, all cables must conform to this.
