Just remember, at long distances, you shouldn’t expect absolutely perfect performance. The visuals might be okay but you could encounter input lag and other issues. Generally, for media-watching, it’s not a problem. This mostly applies to PC, where cards like the GTX 2080 Ti can actually pull off 120 frames per second in certain games while running in 4K. The PS4 Pro and Xbox One X won’t allow 120Hz in 4K anyway. At most you’ll be able to get 120Hz in 1440p with some televisions and monitors, though you’re more likely to be limited to 120Hz in 1080p, even if you have a very fast 2K display.
HDMI 2.1 cable for TVs Has anyone found a working 4k120hz HDMI 2.1 cable for TVs
We have found that the Monoprice 8K certified braided HDMI 2.1 cable offers an excellent solution for those seeking top-notch performance and compatibility. Whether you're a casual viewer or a dedicated enthusiast, this cable delivers the reliability and quality necessary to elevate your home entertainment experience. For an HDMI 4K 120Hz connection, this most recent generation of the unified cable offers bandwidth in excess of just about anything that has come before. That enables it to not only support 120Hz at 4K, but up to 144Hz, and even 240Hz if you leverage Display Stream Compression (DSC). Even 8K resolution at 60Hz isn't outside the realm of possibility with such compression, either. 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. While the design and construction of the cable might not make any difference to your image or sound quality (as long as it works properly), it will make it more robust and reliable, or affect how easy it is to connect your screen and source devices.Gold-plated connectors make a marginal difference with analog signals, because the connections don’t oxidize, but they don’t matter at all with the digital signals an HDMI cable carries. If you care about a solid picture, you only need to pay attention to a cable’s speed rating and length, and whether it’s passive or active. That’s it. HDMI cables vs. HDMI specifications HDMI cables can deteriorate over time. If you're plugging and unplugging the cable consistently, it will wear down faster, and HDMI cables made of better materials last longer. Eventually, though, HDMI cables will become faulty. As we mentioned above, just because you're getting a new TV doesn't necessarily mean you need new HDMI cables, even if you're upgrading to something with 4K and HDR. Over short distances, say under 6 feet, just about any recent "high speed HDMI cable" should work fine. "High Speed" is the rating used by HDMI companies to indicate cables that have the bandwidth to handle 1080p and greater video resolutions. An HDMI cable can still work over long distances, but you might run into graphical artefacts, a loss of brightness, input lag, a low refresh rate, and other issues. When you start encountering those issues, you can bet that the cable is running into issues. HDMI 2.1 has 48Gbps carry capacity, compared to just 18Gbps for HDMI 2.0. Now, the 18Gbps of HDMI 2.0 assumes video delivery with HDR, 4:4:4 chroma, and 10-bit color coding. At a resolution of 3840 x 2160, that would fill up the entire bandwidth with a maximum framerate of 60Hz, and often 4:4:4 won’t be possible, only 4:2:2. However, if we can force 8-bit color coding (16.7 million colors), no HDR, and 4:2:0 chroma subsampling, then 4K 120Hz actually turns out to “cost” about 16Gbps, which is technically possible on HDMI 2.0.
Best HDMI cables for 4K and HD TVs | TechRadar
Certified or tested cables have been tested to make sure they work reliably, and that they’ll support the resolutions and gaming/AV features that they should based on their category. Otherwise, there are a few cables with different swivelling or 90-degree connectors that might make it easier to use them with a screen that’s in a constrained space or mounted on a wall. 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. There are also different types of HDMI cables made with different materials. There are HDMI cables made with copper and others made with fiber optic. Fiber optic HDMI cables are mainly made for reaching farther than standard copper HDMI cables while keeping the high speed of the HDMI 2.1 specifications. To put it another way, a poorly made 3-foot cable will probably work fine for most people, but a poorly made 15-foot cable probably won't. With any long-run solution you're considering, make sure it can handle 4K/60, HDR and so on. Many options can't. There are three technologies to consider:
Active: An active HDMI cable has a small chip built into the cable that takes a little power from the device's HDMI connector and uses it to boost the HDMI signal. These cables cost a little extra, but are far more likely to work. A long passive cable might work for you, but it might not. It depends on your gear. Since they're not significantly more expensive, they're worth considering for any long run. The technology is quite different. Regular HDMI cables transmit electricity through copper, while optical cables transmit light waves through fibre-glass. You probably already guessed which one can transfer data further. Depending on what resolution you want to run at a high refresh rate, HDMI 120Hz may be more achievable on HDMI 2.0, or HDMI 2.1. If you're willing to buy a 4K 120Hz HDMI cable, though, there's no real limit to what kind of resolution and refresh rate you can hit with HDMI. HDMI 120Hz at 1080p Before you go ahead and buy a fibre optic HDMI cable, there are a couple of things you need to know. For starters, they’re a bit more expensive than regular HDMI cables, especially certain brands. Active Fibre optic HDMI cables (AOC) can carry digital information much further than copper HDMI cables, and they have great protection against outside interference too. Another reason people prefer these HDMI cables is that the wires are more flexible, so they’re easier to install and cable manage.
The Best HDMI Cables of 2023 - How-To Geek
These cables tend to be a bit pricier than those that support HDMI 2.0 or lower, but that, unfortunately, comes with having the latest and greatest tech. You can even do up to 144Hz if your display supports it. For uncompressed higher resolutions, though, HDMI 120Hz connections need a next-generation HDMI connection. HDMI 120Hz at 1440p As mentioned above, an HDMI cable is just a conduit for data to travel along. You can think of it like a pathway: Choose a wider one (i.e., higher bandwidth) if you have more data that must march along it at the same time.

To extend an HDMI cable, another option is to use a Cat5 or Cat6 cable. This option isn’t the best because you need two Cat cables to transfer the signal from one HDMI cable. That creates a lot of cables. I would only recommend this if you already have Cat cables lying around that are not in use. As long as that pipe is "big" enough, which is to say it has enough bandwidth, you should be good to go. The 18Gbps bandwidthmentioned above came about with the HDMI 2.0 spec, so if a cable claims it, it's likely built to handle the additional data that HDMI 2.0 connections can provide. The new Ultra High Speed cables are capable of 48Gbps, but that's far beyond what any current source can send. While this cable solved the problem it only lasted approximately 6 months and the problem returned. It seemed to happen only during certain broadcasts, the channel made no difference (failure due to not being able to handle the amount of information?).
