There must be miles of redundant supposedly properly speced High speed 18Gbps HDMI 2.0 cable that has been found lacking in real world use especially on the long runs required for projectors (10 meters)
If anyone who has recently changed kit to embrace UHD and has dropout issues their HDMI cable is an easy target and usually gets the blame.
It then becomes an expensive potluck minefield finding which HDMI cable will perform trouble free.
At the moment "Premium certified" cables are only available in short lengths
An example being my Oppo 203, with a 10 meter High speed 18Gbps HDMI, to a Epson 9300
Playing a UHD discs start fine other than a few seconds of blank screen then 5- 10 mins into the main feature the screen goes blank for a couple of minutes (this can happen a couple of times) the sound continues then video recovers and the movie will usually play Ok
Yes Dolby Vision can apparently be delivered over HDMI 1.4, although I have to say my AVR can't pass DV and that has HDMI 2.0 so I have my doubts but it can obviously be delivered over HDMI 2.0 with certain chipsets. In fact HDR10+ might not actually require full HDMI 2.1 either but we'll have to wait and see. As for Dolby Atmos, that can be delivered via DD+ but for lossless object-based audio you'll need eARC, although that can also be delivered via HDMI 2.0. So apart from features like 8K, 12-bit and HFR, we might find that the manufacturers find ways of delivering the other aspects of HDMI 2.1 by actually using HDMI 2.0.I seem to recall reading that Dolby Vision actually works okay over lowly HDMI 1.4, but HDR10 needs HDMI 2.0.
Also, doesn't Atmos (DD+) work over HDMI 2.0 and ARC as well?
I think it will be a feature of HDMI 2.1 but it's possible that like many of the features included in HDMI 2.1 it could be delivered via HDMI 2.0 under certain circumstances.Very interesting steve.
So, the VRR feature, I'm presuming would require a compatible tv/monitor like the g-sync/freesync monitors?
Or would this be a default feature of the hdmi 2.1 connection??
Happy new year by the way everyone
Many, although not all, 2017 TVs are 10-bit and they can accept a 12-bit signal but genuinely 12-bit panels are still a few years away. As for 14- or 16-bit, well that's a long way off but like I said, the idea behind HDMI 2.1 is to have a standard that will be applicable for decades.Thanks Steve - 'Once you include the support for Rec. 2020 and up to 16-bit colour, you quickly realise the new specifications cover any format that’s even being considered let alone used.'
The item that caught my eye is the 'up to 16-bit colour' as I would love to know where we are in terms of this.
My previous TV was a Full HD LCD Toshiba 42in that had a 10-bit panel but only 8-bit 'circuitry?'
My current Samsung 4K (2015 model) JU6400 50in has something called PurColor
'Using an advanced picture quality improvement algorithm, Samsung’s Wide Colour Enhancer drastically improves the quality of any image and uncovers hidden details. Now see colours as they were meant to be seen with Wide Colour Enhancer.' which maybe 10-bit? or 8-bit with 10-bit colour interpolated?
Are 2017 4K models 10-bit or maybe 10-bit with 12-bit colour interpolated OR are any yet fully 12-bit? And do we have an idea as to the time-line towards higher 14-bit etc? Thanks.
EDIT Researching more - my TV has 'Active crystal colour' the PurColor is on the 55in model (unless these to are interchangeable terms)
Great feedback thanks for that I will now look at the suggested alternatives@Lesmor I have 5 of the same HDMI cables (the 5 metre one). One of the five had to be exchanged fairly early as it started dropping video after a couple of weeks of use. Sometimes unplugging the cable would bring video back, but it got worse and it was definitely the cable as I swapped it around with the others. The only trouble I have now is that I occasionally get sparklies and/or loss of video (which normally returns after switching inputs on TV), but strangely it only occurred when I upgraded my PS4 to a Pro and is fine on other devices... My experience of these cables is that they seem top quality & really robust, but I probably wouldn't purchase them again.
I personally use a company called Kabeldirect, they have an ebay store and produce very good quality cables and reasonable prices, i fell for the old expensive "premium hdmi cable" trick once before, I'll have a check out of neet cables......I've bought lots of HDMI cables on Amazon from a company called Neet (neetcables)...zero issues no matter what configuration or length of cable I need. A quick look at the reviews will show how reliable they are- and they are dirt cheap (affordable- not poor quality)
Just avoid the unbranded HDMI cables with no reviews you should be ok.
Sparkles (flat out noise, like an analogue 'snow' at times) blighting my Xbox One S at the moment, but only on the HDMI ARC channel at 60hz with HDR and even then it's only intermittent, fine on HDMI 2 at all times using the same standard Xbox cable. I'm changing cables before I jack the telly in(for the second time!). It's a Sony 43XE8005 and enhanced HDMI is active, but I think the ARC is to blame here.
I've ordered a certified premium HDMI cable to handle it, if it doesn't work I'm going on a rampage of some description.
