Screen size (inches)

Screen size (inches)

The size of a display is typically indicated by the distance (in inches) between two opposite corners. One problem with this method is that no distinction is made between aspect ratios although the area decreases with the same diagonal the less square the display is. For example, a 21" 4:3 aspect ratio display has an area of approximately 211 square inches, while a 16:9 21" monitor has an area of only approximately 188 square inches.

The High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA.

D-Sub connector

A VGA connector as it is commonly known (other names include RGB connector, D-sub 15, mini sub D15 and mini D15) is a three-row 15 pin DE-15. There are four versions: original and DDC2 pinouts, the far older and less flexible DE-9 connector, and a Mini-VGA used for laptops.
The common 15-pin VGA connector found on most video cards, computer monitors, and other devices, is almost universally called "HD-15". HD stands for "high-density", which distinguishes it from connectors having the same form factor but only 2 rows of pins. However, this connector is often incorrectly referred to as a DB-15 or HDB-15.[citation needed]
"VGA connectors" and their associated cabling are almost always used solely to carry analog component RGBHV (red - green - blue - horizontal sync - vertical sync) video signals along with DDC2 digital clock and data.
Where size is a constraint (such as laptops) a mini-VGA port can sometimes be found in place of the full-sized VGA connector.

Power consumption (standby)

In electrical engineering, power consumption refers to the electrical energy over time that must be supplied to an electrical appliance to maintain its operation. The power consumption is usually a result of power used to perform the intended function of the device plus additional "wasted" power that is dissipated as heat, vibration and/or electromagnetic waves.
