Those who used HDMI 2.1 cables over 3 meters on their TVs or receivers often experienced signal degradation or stability issues when viewing their content. For those who wanted to watch content that needed the full 48Gb/s ultra-high-speed cable, the only option was an external power supply with an active HDMI 2.1 cable.
New HDMI technology enables farther connections
All these requirements can be left behind with the new HDMI 2.1a Amendment 1 version. With the innovation, game consoles and receivers will be provided with a strong signal even on longer HDMI cables. With the additional power feature called Cable Power, it is aimed to prevent signal degradation and stability problems.
In order to use this feature, both the cable and the devices must support the Cable Power system. Another important point is that the cable is installed in the right direction for the efficient operation of this system, which works in one direction.
For those who do not support this feature on their current hardware, USB Micro-B and Type-C connectors will be offered. In this way, by providing extra power, it is aimed that users can connect without any decrease in image quality.
However, it seems unlikely that this new feature will be used directly on existing devices. It seems that a new chip will need to be used in the devices for faster transfer. This means that your hardware will not get the new HDMI 2.1a feature with just a manufacturer update.
On the other hand, televisions, monitors and especially projectors with 4K and 8K image quality will be able to reflect the image they receive from a transmitter more than 10 meters away without any distortion.
We’ll probably have to wait for newer hardware to use this feature. The long-awaited PS5 Pro is expected to support HDMI 2.1a. So what do you think about the new HDMI cable that can provide images from longer distances?
