for example, if i have a 1920 x 1080 display and send it a 1920 x 1080 video, would that put less of a load on the cpu/gpu than if i have a 3840 x 2160 display and send it a 3840 x 2160 video?
Yes. 1920x1080 is simply 1/4th the data for the video card to process. In addition, that video is not uncompressed. So you're also having to decode the video and it's going to be higher bitrate and perhaps a more difficult to decompress codec (h265 vs h264).
