Why do computers need GPUs (integrated or external)? What information is the CPU sending to the GPU that it can’t just send to a display?

If we’re talking about a 3D game, the information that the CPU passes to the GPU is stuff like the shape of the objects in a scene, what color or what texture that object has and where they are located. The GPU will turn that into a picture that your monitor can display. The way you go from a bunch of shapes and colors to a picture involves a matrix multiplication, which is something that a GPU can do a lot faster than a CPU.
