Most people also report that fibre optic cables, when compared to the usual copper ones, transmit clearer images with more colour, at the same lengths. Generally, with fibre optic HDMI, the signals are much stronger and can be pushed further because the technology doesn’t allow the signal to degrade. While there are many pros to using fibre optic HDMI cables, there are also some downsides too. What’s the Maximum Length for a Fibre Optic HDMI Cable? Besides resolution and the maximum refresh rate, the limits are also determined by the Bit Depth (Color Depth), which refers to the amount of color info stored in an image. Most monitors and TVs have a bit depth of 8-bit, but some displays can display higher amounts. The higher the bit depth, the more colors stored in an image. The cable supports Dynamic HDR, Dolby Vision, Dolby Atmos, and DTS:X surround sound. Meanwhile, you can output to a display with up to an 8K resolution at 60Hz, as well as 4K at 120Hz. 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). Despite their size, they still offer enough bandwidth to handle a 4K 60Hz connection, or 1080p at 120Hz, with Cable Matters' standard build quality ensuring they will be durable over the long term.

HDMI 2.1 cables can handle up to 120 Hz when using 4K resolution and 60 Hz when using 8K resolution. Lower resolutions than 4K can all handle up to 240 Hz when using an HDMI 2.1 cable. 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 Fiber optic HDMI cables are like standard HDMI cables but made with optical fiber inside the cable and meant for farther distances up to 164 ft (50 m) for 4K @ 60 Hz.This cable also supports 8K resolution and 4K at 120Hz, has a gold-plated HDMI connector for corrosion resistance, and is available in sizes up to 16.5ft.

One option would be to buy a small device called an HDMI signal booster, also known as an HDMI repeater. What these devices do is, in simple terms, add more power to the cable, to boost the digital signal. The devices strengthen the HDMI digital signals. They have an HDMI input and output, and an external port for power, usually micro-USB. These specs tie into the HDMI connection standards, which is why you might see some Category 3 cables listed as HDMI 2.0 cables and some Category 3 (8K) cables listed as HDMI 2.1. Basically, if you have a 4K console with an HDMI 2.0 output and a 4K HDR TV with an HDMI 2.0 input, then you’re going to need a Category 3 cable running between them, or you run the risk of only getting 4K at 30Hz. We have found that the Anker 8K 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.If you have an HDMI 2.1 compatible device, like a PS5 or Xbox Series X, you need to make sure that you find a cable that can pass a 4K/120Hz (or 8K/60Hz) signal instead. If the HDMI cable(s) you have on hand can’t meet your requirements—say, playing 4K content at 120Hz or with HDR—then you’ll need to shell out for a new one. You can also buy a new cable if you want to ensure compliance with a particular HDMI spec. For example, Ultra High Speed HDMI cables must be certified to earn the label, and should thus have guaranteed compatiblity with HDMI 2.1 devices like the PlayStation 5 and Xbox Series X. You want to hide your HDMI cable inside the wall If your source device is at one end of the room and your display is at the other (such as a video projector and its screen), or if your source and display are in different rooms, you might need a cable with a built-in signal amplifier to ensure the data can be transmitted from one end to the other. You’ll commonly find these cables classified as “active” HDMI cables (preface each of the cable types we’ve already discussed with “active”). Another solution for long cable runs is an HDMI signal booster, such as the Key Digital KD-HDFIX22. 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. 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.
