How to calculate the p of a monitor resolution based on this Post Description question ?

[elreydelaswasas1]

If 720p is a 1280*720 monitor resolution how many ps are 1280x1024 monitor resolution ?

The p is nothing to do with the 720. It refers to how the image on the screen is drawn out each frame.

p = progressive
I = interlaced
