FHD (1920x1080)
The FHD or Full HD resolution of 1920x1080 pixels in a 16:9 aspect ratio was 
developed as an HDTV transmission and storage format. Using interlacing, the 
bandwidth requirements are very similar to those of 720p – their pixel 
counts are roughly in a 2:1 ratio, 9:4 exactly. FHD is 3 times the width and 
2 1⁄4 times the height of 4:3 VGA.

Due to its origins, this resolution is sometimes referred to as 1080i 
wherein the i stands for "interlaced". Since there are also progressive 
signals with the same frame rate (but half the effective field rate) those 
signals are more commonly called 1080p.

Since most video codecs use 16x16 pixel macro blocks there is often an 
excess 8 lines encoded, for 16 times 68 equals 1088.
