A Chinese tech alliance has unveiled GPMI, short for General Purpose Media Interface, a new wired audio and video standard offering up to 192 Gbps of bandwidth and up to 480 W of power delivery.

The key question is whether it can realistically replace HDMI and DisplayPort, and what that would mean for gamers, home cinema systems, and high-performance laptops moving toward 8K and single-cable setups that combine video, data, and charging.

Development: Technical Details and Practical Impact

The specification comes from the Shenzhen 8K UHD Video Industry Cooperation Alliance and is divided into two connector types.

  • Type C keeps the USB-C form factor and supports up to 96 Gbps with up to 240 W, effectively doubling the common 40 Gbps ceiling of USB4 while matching high-end power delivery profiles.
  • Type B introduces a dedicated connector and unlocks the full 192 Gbps and 480 W, clearly exceeding HDMI 2.1 at 48 Gbps as well as Thunderbolt 4 at 40 Gbps and 100 W.

At 192 Gbps, there is sufficient throughput for uncompressed 8K at 120 Hz with HDR without relying on Display Stream Compression, which improves signal fidelity and reduces compression overhead in high refresh scenarios.

Higher bandwidth also enables bidirectional multi-streaming, meaning video, data, and control signals can travel simultaneously over the same link, which is relevant for advanced docking stations, multi-display environments, and integrated desk setups.

Power delivery up to 480 W changes laptop and eGPU scenarios in practical terms. A gaming laptop could receive full charging power while driving a high-resolution external monitor through a single cable, and an external GPU would face fewer interface limits compared to current 40 Gbps connections.

The standard also supports bidirectional device control similar to HDMI CEC, fast wake protocols for reduced resume times, improved energy efficiency under load, and daisy chaining of compatible devices, all of which target integrated home entertainment systems and workstation setups.

Market Strategy and Realistic Outlook

Companies involved include TCL, Huawei, Hisense, and HiSilicon, which gives the standard a strong manufacturing base in televisions and display hardware. The Type C variant has reportedly been licensed in alignment with USB governance structures, potentially easing integration into existing USB-C ecosystems. The rollout plan prioritizes home entertainment, then automotive and transport, followed by industrial applications.

Several factors remain unclear. There is no confirmed global consumer launch timeline, and maximum certified cable length at a full 192 Gbps has not been specified, which will matter for real world installations and complex routing scenarios. Licensing terms outside the core alliance markets and support from major GPU vendors will determine whether GPMI gains global adoption or remains regionally focused.

At the moment, HDMI 2.1 and DisplayPort 2.1 already handle what most gamers actually use, whether that is 4K at 120 Hz or high refresh 1440p on PC. GPMI pushes the ceiling much higher in terms of bandwidth and power delivery, and features like bidirectional multi-streaming and full 8K support make it technically impressive on paper.

It also positions itself as a single cable solution for video, data, and high-wattage power in one link, which could simplify future desk and living room setups. Still, none of that matters unless graphics cards, monitors, laptops, and future consoles adopt it at scale, because real-world support across the ecosystem will decide its future, not just the numbers on a specification sheet.
