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: 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.

How To: HDMI 120Hz - Cable Matters

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 To get HDMI 120Hz at native 1440p, the best connector is HDMI 2.0. It has double the bandwidth of HDMI 1.4, supporting both 1440p at up to 144Hz and 4K at up to 60Hz without any form of compression. A higher bit depth also takes up more data since more information is stored in each image. Because of this, if you raise the bit depth, it may affect how high of refresh rate you can use.

For example, you can run a 15-meter cable from your computer to repeater, connect another 15-meter cable to that repeater, and finally to a display. This solution works okay for outdoor projectors or digital signage. Use HDMI to Cat5 or Cat6 Adapters 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. After conducting our research and analysis, we have found that the Cable Matters Active 8K Fiber Optic HDMI 2.1 cable offers exceptional performance and a range of impressive features. The effective range is much better than regular HDMI cables, which start to run into issues around the 50 ft mark. So if you need to run an HDMI cable over a long distance, fibre optic is definitely the best, albeit expensive, choice. The Downsides to Fiber Optic HDMI Cables 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.

Several “buts” if we’re being honest. If you’re on PC, then you may as well save yourself all this video math by going with DisplayPort, which since version 1.3 has been able to do 4K 120Hz with ease thanks to an effective bandwidth of nearly 30Gbps. This is why you have plenty of wonderful 100Hz and above monitors in and around 4K to choose from in the PC realm, as DisplayPort is standard in that context. However, HDMI offers a far more universal approach and works equally well for PCs, consoles, and a whole host of input sources, like streaming boxes. While USB-C alt mode may increase the ubiquity of DisplayPort, for now HDMI is the more popular. Which is why we thought you’d want to know that 4K 120Hz is already doable with HDMI. With a bandwidth of 48 Gb/s, it supports high-resolution formats like 8K at 60 Hz, 4K at 120 Hz, VRR (Variable Refresh Rate), Auto Low Latency Mode (ALLM), and and chroma 4:4:4 (no compression), all while delivering stunning Dolby Vision HDR (10 bit/12 bit color depth). Standard HDMI cables are made of copper and have limited ranges and speeds, which you can learn about below in the section: Max HDMI Cable Length . 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 original Standard or Category 1 cables were certified to handle 1080i or 720p video. The later High Speed or Category 2 cables took the bandwidth up from 4.95Gbit/sec to 10.2Gbit/sec, which meant they could transport 1080p video at 60 frames per second or 60Hz, or 4K video at 30fps or 30Hz. Category 3 or HDMI Premium cable reaches 18Gbits/sec and supports 4K video at 60Hz, while the highest spec Category 3 (8K) or Ultra cable can do 4K at 120Hz or 8K at 60Hz.What you do is plug the signal booster into a power source, and then plug an HDMI into either end. These signals can boost the usable distance of cables.
