HDMI 2.1 cables are upgraded from the HDMI 2.0 standard and have many significant upgrades compared to HDMI 2.0 cables. The main difference is that HDMI 2.1 added many additional features and improvements and increased data transfer speed.

Another thing to keep in mind is that sharp bends can degrade the signal further. In short, if you’re planning to run an HDMI cable through your home, the end result might be either a completely blank screen, or a low-quality image. The easiest high resolution to hit 120Hz at is 1080p. It's not only achievable on earlier generations of HDMI connection, but the hardware you'll need to achieve it is a relatively low bar too. The Xbox One X and S, and most gaming PCs of recent years can achieve this in the right game. As long as you have at least HDMI 1.4, 120Hz is doable on your compatible TV or monitor. Additionally, it boasts support for eARC (enhanced Audio Return Channel), allowing for enhanced audio transmission. It is compatible with Dolby Atmos, Dolby Vision, and DTS X surround sound.We understand that the technology industry is constantly evolving, and we strive to stay up-to-date with the latest trends and developments. However, we recognize that there may be occasions when errors or inaccuracies slip through, despite our best efforts. When it comes to cables, one of the most common mantras is, “It either works, or it doesn’t”. Sometimes, it’s not that simple. In some cases, a long cable will just be unreliable.

HDMI 2.0 and 2.1 Support 120, 144, and 240 Hz? Does HDMI 2.0 and 2.1 Support 120, 144, and 240 Hz?

With a bandwidth of 48 Gb/s, it supports high-resolution formats like 8K at 60 Hz, 4K at 120 Hz, and chroma 4:4:4 (no compression), all while delivering stunning Dynamic HDR. The issue is I need a 5M long cable, I already have a 5M long cable that can do 4K 60Hz/HDR at RGB Full / 8bit. However this cable when I plug it straight into the TV rather than via my amp causes a whole world of issues, it allows me to select 10 and 12 bit, but the screen will loose signal and restart PC is required, in worst case booting the PC into safe mode and remove Nvidia drivers. CAT-7 cable, while it may work just fine, is not an IEEE recognized standard nor is it approved by TIA/EIA. It also doesn't use standard RJ-45 (8P8C) connectors. It uses GG45 connectors, unless that's changed. Performance-wise, solid core CAT-6 or 6a, UTP, (non-CCS/CCA and not pre-terminated ethernet) cable is recommended, and is probably cheaper. To use CAT cabling for HDMI you need to terminate with HDBT, which works quite well but currently carries compressed data. The new chipsets (VS3000) are supposed to carry un-compressed data but I don't know if they have been incorporated yet into the units.

Technically, fibre optic cables can run for miles, maybe 40 to 60 miles, but most manufacturers won’t make HDMI cables in those lengths. Generally, fibre optic HDMI has almost no signal loss over distance.
