Not sure if your posted these because you think the ppi numbers contradict what I said about the screen sizes?
It's the physical size (inches) of the screen which matters not the pixels. Objects or people in a movie or photo in landscape mode will appear smaller on the X because physically the screen is narrower on the X.
Divide the pixel dimension by the ppi to get the inches.
The greater ppi number means the X image will be theoretically sharper, but the difference will not be noticeable.
