Probably never going to see passive copper cables at that sort of length that support this speed. Just too hard to maintain the signal at that length. You'll probably need an optical solution.
The fiber optic cables are expensive, but my 100-footer from Monoprice works perfect for 4K60 4:4:4 or HDR modes. I assume this will be the future of most HDMI 2.1 cables over 10 feet.
I run a 30ft HDMI 2.0 cables no problem to my projector and 45ft 1.4 no prob. Anything longer and I've had issues. Per bandwidth channel has bumped from 3.4 to 6 and now 12!. Is there a corresponding increase in voltage to prevent attenuation or are we going to end up with ridiculously short cables?
Attenuation isn't the only issue. It's also the crosstalk between the differential pairs in the cable. A longer cable gives more distance over which crosstalk can occur. Higher voltage will just increase crosstalk if you haven't compensated for it in some other way, such as the individually shielded pairs in this cable.
CMRR is p high in the amplifiers and alien crosstalk is essentially a non-issue with shielding. Near end crosstalk can be cancelled out through fancy receiver tricks.
Attenuation is the largest issue. The higher the frequency, the more attenuation you'll have. When they're bumping up to insanely faster serial speeds they're running up to what high speed ethernet is spending a Lot of money on developing. HDMI is mickey mouse by comparison. It's just a cheap consumer solution. It's almost a miracle it works as well as it does.
My understanding is that HDMI 2.1 with display stream compression can deliver up to 4K @ 240 Hz, which would cover what you listed and 4K @ 144 Hz, which is apparently something that exists: https://www.theverge.com/2018/10/1/17914550/acer-p...
Still Nervous that the industry will produce fast 4k nvidia g-sync TN monitors with 1ms GtG but not support 3d Vision as well. Sure OLED would be fast enough to support as much also if they ever made a fast 27" to 32" 4k OLED 10 bit p3/rec 2020 HDR display that supported the die hard 3d gaming fan base community with 3D vision support on displays ( that support nvidia tech anyway ) that shader hacks it's own solutions nowadays... I could finally sleep easy knowing my displays are future proofed for my favorite gaming technology ( stereoscopic aural and visual immersion for those of us with two ears and eyes ) before 3d vision dies.
With the stereoscopic investment going into VR/AR... Find it easier to create assets respecting the experience of depth fidelity by using a lightweight solution like 3d glasses which can be slapped on quickly over leveraging a heavy cumbersome VR HMD to simply gauge an assets charm ( or lack of ) when viewed stereoscopically! Which can expose blatantly obvious artifacts not apparent when viewed flat/2d. lowpoly cheapness and normal map depth fails particularly stand out revealed in their naked depth reality where their low fidelity cheapness can not hide in 2d.
Kind of sad that very few creatives I know personally do not work on stereoscopic projects like VR respecting the creation of their assets as viewed in their final depth revealed form/experience. I liken it to an audio engineer or musician that monitors their stereo/surround audio soundtrack/music mix in mono reference only and expecting an honest result for their end users.
It would be really nice to see an analysis of pre- and post- DSC 2.1 compression images. "Perceptually lossless" claims given by vendors often apply to average-joe-off-the-street, the same people that can't tell the difference between DVD and Blu-ray.
It's hard to even find pre/post screen captures, which leads me to believe something is up.
I have one of the earlier 4K sets with HDMI 2.0 - but it doesn't support HDCP 2.2 properly so a lot of content will downgrade to 1080p. Not falling into that trap again.
How did you fall into that trap in the first place. When those first HDMI 2.0 sets went on sale there were warnings all over the internet not to buy them because they wouldn't support HDCP2.2.
What's so special with this Club3D HDMI 2.1 cable release? I have had a Belkin HDMI 2.1 (48Gbps) cable for almost one year now. https://i.imgur.com/yyPmavq.jpg

1 & 2m?!lol and here I am waiting for 15m cables for my projector.

There's also external noise picked up by the cables acting as antennas.willis936 - Friday, November 30, 2018 - link

"The ample _of_ bandwidth HDMI 2.1 provides enables it to support new UHD resolutions _an_ refresh rates"One does not simply post an Anton Shilov article without doing a grammar check.
sparkuss - Thursday, November 29, 2018 - link
4Kp120Is that what is required in a cable for the newer PC monitors that are finally pushing 4K 100 and higher refresh rates?
And with backwards capable a good investment for now and when I can afford one of those newer monitors?

A displayport 1.4 capture card would work. They're not cheap though.Anato - Thursday, November 29, 2018 - link

Before you early adopters buy HDMI 2.1 equipment, you may want to ensure it supports HDCP 2.3 (yes, a new version is coming).atomt - Friday, November 30, 2018 - link

Interesting device, but I suppose we'll have to wait for the "Blackbird 8K Pro" in order to take advantage of HDMI 2.1 and HDCP 2.3 -> 2.2/1.4.Harry Lloyd - Saturday, December 1, 2018 - link
