The interface between a computer's [[CPU]] and the display is a [[Graphics Processing Unit]] (GPU). This processor is used to form images on a [[framebuffer]]. When the image is to be sent to the display, the GPU sends its image through a [[video display controller]] to generate a [[video signal]], which is then sent to a [[List of video connectors|display interface]] such as [[HDMI]], [[VGA]], or [[DVI]]

GPUs can be divided into [[discrete GPU|discrete]] and [[integrated GPU|integrated]] units, the former being an external unit and the latter of which is included within a CPU die.<ref>{{Cite web|url=https://www.technipages.com/discrete-vs-integrated-graphics|title=Discrete vs Integrated Graphics|website=Technipages|date=22 July 2020 }}</ref> Discrete graphics cards are almost always connected to the host through the [[PCI Express]] bus, while older graphics cards may have used [[Accelerated Graphics Port|AGP]] or [[Peripheral Component Interconnect|PCI]]. Some mobile computers support an external graphics card through [[Thunderbolt (interface)|Thunderbolt]] (via PCIe).
