Reply to comment by BobbyThrowaway6969 in ELI5: 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? by WeirdGamerAidan
Yep, no reason a CPU couldn’t output video, in fact some do! And I’m not even referring to integrated graphics in APU’s, I’m talking about arduinos and stuff. Hook them up to little LED matrices, 32x128 oled displays, or whatever else you desire, and boom, you have a CPU giving a display output. These are just very low resolution, low refresh rate, and often black and white. Could obviously do better with a real CPU, but it would still be reallly bad
