I = interlace (this is how traditional televisions have always worked)
picture is scanned zig-zag left to right from top to bottom 540 times across, then rescanned in between those “lines” 540 times again creating 1080 horizontal lines in 2 passes
P = progressive - this is better performance
1080 scans in one single continuous swipe
60, 120 240hz (hz = times per second) is the “refresh” frequency or how often the screen is scanned from top to bottom - higher is better
