1, the difference of technical support:
AMD multi-screen splicing technology must have DisplayPort interface. Users need to connect with the display equipment supporting the interface through the DisplayPort data cable to become the main display of the three-screen splicing display, and they must connect directly through the DisplayPort interface without any form of conversion.
2. Differences in bandwidth support:
At present, HDMI 1.3 interface can support signal transmission with bandwidth of about 10.2Gbps, and DisplayPort interface can support signal transmission with bandwidth of 10.8Gbps, which has obvious advantages. With the advantage of ultra-high bandwidth, DisplayPort can easily support ultra-high resolution displays such as 2560× 1600.
3, the manufacturer's production cost is different:
DP interface technology is free. Unlike HDMI interface, the latest DisplayPort interface does not need to pay a certain annual membership fee, nor does it need to pay for every product with HDMI interface like HDMI interface. It's completely free. Therefore, DisplayPort interface has won strong support from many internationally renowned manufacturers.
