This project is a DisplayPort to embedded DisplayPort adapter with touch integration and input switching. The eDP standard is for laptop displays and other embedded devices. This adapter repurposes a laptop display panel as a monitor for external devices such as other computers. The adapter makes use of USB-C DP Alt Mode for DisplayPort input. Using a type-c controller and USB-C receptacle, it senses USB-C orientation and communicates with host devices to setup a 2-lane DisplayPort configuration. The adapter flips the video signals based on the orientation of USB-C input. Touch integration is also included for touch displays, and passes through the USB-C port as well. The adapter can switch between 2 inputs and is theoretically capable of switching between video inputs up to 4K at 30hz or 3k at 60hz.
