Many functions with one cable! Can GPMI replace HDMI, know the difference between the two

If you want to connect a TV, monitor, laptop or gaming console to any other device, the first name that comes to mind is the HDMI cable. It has long been used to transfer audio and video. But now a new name is buzzing in cable technology, GPMI stands for General Purpose Media Interface.

It is jointly developed by more than 50 Chinese tech companies. Its specialty is that it is not limited to just sending video and audio. Through GPMI, video, audio, data, network, control signals and even power can be transferred through a single cable. This means that the need to install multiple cables for different purposes can be reduced. So can GPMI replace HDMI in the future? And will its picture quality be better than HDMI? Let us explain you in simple language.

There are two types of options available in GPMI

GPMI is presented in two formats: Type-C and Type-B. Both have different capabilities. Type-C has a connector similar to USB-C. It supports bandwidth up to 96Gbps and power delivery up to 240W. While in Type-B a different type of connector is provided. Its bandwidth is up to 192Gbps and it can support up to 480W of power.

Both formats have support for 8K video. That is, GPMI is designed with tasks requiring high-resolution displays and high data transfer in mind.

What is the specific difference between GPMI and HDMI?

The biggest feature of GPMI is its all-in-one design. Typically larger AV setups may require separate cables for video, audio, network, and power. But GPMI is designed in such a way that many types of signals can be handled from a single connection.

This can help reduce the amount of cables and make setup easier to manage. It can be especially useful in applications such as 8K displays, video walls, digital signage, conference rooms and gaming. On the other hand, HDMI is widely used to send audio-video signals to TVs, monitors, gaming consoles and other devices.

Which has better picture quality?

GPMI’s specialty is its high bandwidth and 8K video support. Its Type-B format offers a bandwidth of up to 192Gbps, while HDMI 2.2 has a maximum bandwidth of 96Gbps. However, more bandwidth does not mean that the picture will look better on the screen in every situation. Picture quality also depends on the display, source device and the content you are using.

One more thing needs to be understood here. GPMI states 8K video support, while HDMI 2.1 and DisplayPort 2.1 are said to output up to 10K and 16K resolutions. So, no one can be said to be the best in every way based on bandwidth or resolution alone.

Can GPMI replace HDMI?

GPMI’s specifications are certainly strong, but the biggest challenge before that is to start using them in more and more devices. HDMI is already present in TVs, monitors, gaming consoles and many other devices. To use GPMI, new hardware and devices that support it will be required. It also does not have direct backward compatibility with older HDMI or DisplayPort devices. This means that you can’t just buy a new cable and use it in an old device.

Overall, GPMI provides an option to transfer multiple types of signals and power through a single cable. But to replace HDMI, it will have to overcome challenges such as support in more devices and increased usage among people. Currently, looking at its features, it is too early to say that GPMI will completely replace HDMI.
