Thanks for the replies, £40 with shipping for BJC 6 foot cableAt 1.5m the best you can do is a Premium High Speed HDMI cable. Those are certified by an Authorized Testing Center (ATC) following the protocols designed and implemented by HDMI.org. Any cable mfr can submit their cables to an ATC for certification. Just look for Premium High Speed HDMI cable and make sure it comes with a QR label for authenticity. I've used BJC Premium High Speed HDMI cables and have had no issues at all with 4k HDR (including Dolby Vision) from any source. Just be mindful of bend radius because you don't want to put any strain on the HDMI input.
If the cable description starts to talk about HDMI 2.0, 2.1, etc just ignore it as Joe mentions above. A Premium High Speed HDMI cable (QR label) means that it has been tested and certified to meet all of the HDMI 2.0b hardware specifications.
I had to change a cable for exactly that problem when I first hooked up my new Pioneer LX500 on UHD content.'Getting sparkles when watching 4k HDR content through a media player, more noticeable on darker scenes.' - do you have any other HDMI cables you can try out before you make a purchase?
Currently using an amazon basics cable, have ordered another amazon basics to test plus a Premium Certified one to test as well'Getting sparkles when watching 4k HDR content through a media player, more noticeable on darker scenes.' - do you have any other HDMI cables you can try out before you make a purchase?
