The DisplayPortTM (DP) is a digital video interface standard, advocated by the Video Electronic Standard Association (VESA), for high-resolution multimedia video transmission like HDMI.
Differing from HDMI, the DP is more IT industry rather than consumer products oriented. Nevertheless, the compatibility issues remain the same, as HDMI does especially after the training session during DP connection. In addition to EDID access, display in correct solution may fail after poor training.
Regarding integration with USB Type-C, for the successful switch between USB and DP mode and communication for power delivery specification and configuration channel (CC) must strive to accumulate experiences with heavy tests in short term.
The embedded display port (eDP) could be another issue. Though it does not require mandatory certification, its signal and environment tests still pose great demands to ensure correct display in each environment when serving the main interface between display panel and processor communication.
