Want hard figures? 1.4a serves up 25.92Gb/s of usable bandwidth for transporting display images; DisplayPort 2.0 ups that to 77.37Gb/s.
As for the implications of the bandwidth bump, they’re numerous. The more bandwidth, the higher the resolution you can display at greater refresh, and with more dynamic range and color fidelity. For example, with DisplayPort 2.0, you’ll be able to drive dual 8K monitors at 120Hz and 10 bits of color per channel over a single interface. In terms…
