- China unveils GPMI, a domestic HDMI alternative with 192 Gbps bandwidth and 480 W power delivery.
- GPMI supports 8K resolution, higher refresh rates, and simplified connectivity with bidirectional communication.
- Two variants available: Type-C (96 Gbps, 240 W) and Type-B (192 Gbps, 480 W).
- GPMI outperforms HDMI 2.1 (48 Gbps) and DisplayPort 2.1 (80 Gbps) in data throughput.
- Standard includes auxiliary links for device management, cable info, and limited USB 2.0 support.
- Type-C variant is USB-C compatible, aiding integration with smart TVs and other devices.
- Aims to reduce China's reliance on Western-controlled standards and costly HDMI licensing.
- HDMI licensing involves annual fees ($10,000 or $5,000 + $1/unit) and per-unit royalties ($0.15-$0.04).
- GPMI expected to be commercialized soon in China and export markets by major companies like Huawei, Hisense, and TCL.
