This page shows the different variations of the Displayport from an Icons8 icon pack. Feel free to resize and recolor the icon, and then download the icon in PNG format for free. Icons are available in PNG and vector.
The icon is basically identical to the logo used for the VESA Display Port standard, an interface allowing for the low-latency and wide throughput transfer of data and media. The icon consists of a stylized D, within which a P is inscribed in negative space.
