Aspect ratios is the width vs height of the monitor.
The Aspect Ratio of modern monitors are typically either 16;9 (widescreen) or 16:10 (letterbox). Resolution is entirely separate. You can have 1080p HD in either format. I have a old Dell 2407 1080p monitor, 16:10 format, that I have loved for many years. 2k and 4k more commonly come in 16:9 format. I just bought a Del S2716DG 2k monitor in 16:9 format.
Movie videos typically use 16:9 ratio. This allows the video to be viewed on the monitor without the black bars on top and bottom of the screen, which is seen using monitors of the 16:10 ratio.
16:10 ratio can have an advantage if using documents, such as Word, Access, etc, in that you have more vertical space on your screen, and can place two documents, side by side, on the one screen more comfortably than the 16:9 format. It is really a matter of personal preference. 16:9 gives you a wide view for movies. 16:10 gives you a bit more vertical view than the 16:9. For gaming, you can use either.
