My monitor is an FHD 24 inches, 1920X1080 resolution, so saving at small resolutions would look horrible on my monitor, I generally save at 480p or 720p. I did so with my previous monitor that was smaller, 16-18 inches or so and had a resolution of 1280X720, 1280X1024, could switch between them. Back then 320p or 480p looked great on my monitor.
