Abstract
Technologies for end-to-end display integrity verification include a computing device with a display controller coupled to a display by a physical link. The computing device generates pixel data in a data buffer in memory, and the display controller outputs a pixel signal on the physical link based on the pixel data using a physical interface. The display receives the pixel signal and displays a corresponding image. A splicer is connected to the physical link and repeats the pixel signal to an I/O port of the computing device. The I/O port may be a USB Type-C port. The computing device compares pixel data received by the I/O port to the pixel data in the data buffer. The computing device may calculate checksums of the pixel data. If the pixel data does not match, the computing device may indicate a display integrity failure. Other embodiments are described and claimed.
