* Consumer usage in 2000 (55% didn't know)
HDTV actual broadcast images are encoded as 1920x1088 pixels because MPEG-2 encoding requires the number of vertical lines to be a multiple of 16.

† Note EVGA has been used for both Enhanced VGA and Extended VGA.

‡ WXGA (Wide Extended Graphics Array) is a set of non standard resolutions. WXGA can be 1280x720 ir 768 or 800 for monitors and 1360x768 or 1266x768 for LCD TVs but becoming more popular for laptops and projectors.

* Viewable area is typically less than the nominal size (measured diagionally) for CRT's.
LCD sizes are for viewable area.
Resolutions of 100 pixels/inch or higher are difficult to read on a CRT, however the clarity of flat panel displays make them usable at higher resolutions.

1. Aspect Ratios: Width to Height
Standard TV - 4:3; HiDef TV 16:10, SLR cameras 3:2, compact digital cameras 4:3
5:4 - 1.25, 4:3 - 1.33, 16:10 - 1.6, 16:9 - 1.78, 25:16 - 1.56
Note: Some LCD (e.g. Viewsonic VP171b) pivot to a portrait mode to give either 4:5 or 5:4.

Color Depth:
32bpp, 24bpp, 16bpp, 8bpp grayscale, and 8bpp pseudo color.
bpp - Bits per pixel

32 bit 16,777,216 (True Colors + Alpha Channel)

24 bit 16,777,216 (True Colors, SVGA)

16 bit 65,536 (High Color, XGA)

8 bit 256 colors (VGA)

4 bit 16 colors (EGA)

2 bit 4 colors (CGA)

1 bit 2 colors (monochrome)

24 and 32 bit modes produce the same number of colors - 16.7 million. They differ only in the organization of video memory (3 bytes per pixel for 24 bit, 4 bytes per pixel for 32 bit).

One of the big things Samsung is pushing with the Note 4's screen is its 2560 1440 QHD resolution. The iPhone 6 Plus' Retina HD display offers a resolution of 1920 1080. That means the Galaxy Note 4's display should be sharper than the iPhone 6 Plus'. But in reality, the pixel densities of both screens are so high that your eyes can't perceive any difference between the two.
