Speaking about 'packet-based approach', the way it's presented in the popular press as if it's similar to Ethernet, is a pretty gross distortion, the impact of which is not nearly as much as people seem to think it is.
You can check that there in this presentation (https://www.vesa.org/wp-content/uploads/2011/01/ICCE-Presentation-on-VESA-DisplayPort.pdf https://www.vesa.org/wp-content/uploads/2011/01/ICCE-Present...), page 32 and 33.
The majority of DP traffic is still brute force video data, interspersed with heavily packetized secondary data.
Over the years, I've spent many hours wading through DisplayPort data debug traces, and I've always wondered what people were smoking when they called it 'packetized like Ethernet'. It's just not true. (And FWIW: even old HDMI can transport secondary data packets just the way you can with DP. It's how audio-over-HDMI is done...)
