Critical Thinking

Every two main types: DVI-D is digital only

Every
gaming platform must have a display for the player to view the game and receive
feedback through this necessary output device, displays can be built-in like on
a phone or handheld platforms, or external like for desktop computers and game
consoles. Modern screens are LCD (liquid crystal display) which are a lot
thinner, lighter, and energy efficient than the older CRT (cathode ray tubes)
screens. The quality of the image that a screen displays is referred to as the
resolution which is the number of pixels on a screen at one-time, horizontal
axis by vertical axis such as 1900 x 1200. The resolution is dependent on the
size of the screen which is measured from one corner to the opposite corner in
inches, the same resolution on a larger screen as a smaller sized screen would
mean a lower quality display as pixels are spread out over a larger distance.

LCDs use a DVI (digital video interface) connection which
transfer video data from the processors without the need to convert digital to
analogue, which CRT displays required with a VGA (video graphics array)
connection. The DVI connections comes in two main types: DVI-D is digital only
and requires a video adaptor and monitor with DVI-D inputs. The other type is
DVI-I (DVI-integrated), this supports digital and analogue signals so a monitor
with either connection would work. Monitors have different modes which describe
how many colours it can display and the bit depth, SVGA (Super VGA) processes a
24-bit depth of a pixel – this means it can show up to 16,777,216 colours
(rounded to 16.8 million). The human eye can only see around 10 million colours
so 24-bit depth is the highest and is known as ‘True Colour’, while 16-bit
depth can only display 65,535 colours. However, 32-bit exist and is used in
games, animation, and digital video to show translucency in objects/images. The
first ever displays that were used in TVs were monochrome; monochrome is just
two colours, today all screens will have 24-bit or 32-bit display.
