Terminology
OSD(On Screen Display)
On screen display (OSD) allows you to customize on-screen settings to optimize the picture
quality as required. You can change the screen brightness, tint, size and many other settings
using menus displayed on the screen.
HUB
HUB refers to a device that is a common connection point for multiple devices connected over
a network. It is used to connect multiple PCs, video devices, office devices and/or LANs over a
single network.
Wireless-connection dongle - for Series 7
only
Dongle refers to a device that connects to an input/output port on a PC. It contains a security
key or ID so that only the user that connects the wireless dongle to their PC can access a
certain application. The wireless-connection dongle itself contains data required for a wireless
connection to work. It must be connected to your PC when a wireless connection is needed.
Gamma
The Gamma menu adjusts the grey scale that represents middle tones on the screen.
Adjusting the brightness brightens the whole screen, but adjusting Gamma only brightens the
medium brightness.
Grey scale
Scale refers to levels of color intensity that show variations of color change from darker areas
to brighter areas on the screen. Changes to the screen brightness are expressed with black
and white variation, and grey scale refers to the medium area between black and white.
Changing the grey scale through Gamma adjustment will change the medium brightness on
the screen.
Scanning rate
Scanning rate, or refresh rate, refers to the frequency of screen refreshes. Screen data is
transmitted as it refreshes to display an image, although the refreshing is invisible to the
naked eye. The number of screen refreshes is called scanning rate and is measured in Hz.
A scanning rate of 60Hz means that the screen refreshes 60 times per second. The screen
scanning rate depends on the performance of the graphics cards in your PC and monitor.
Horizontal Frequency
Characters or images displayed on the monitor screen consist of numerous dots (pixels).
Pixels are transmitted in horizontal lines, which are then arranged vertically to create
an image. The horizontal frequency is measured in kHz and represents how many times
horizontal lines per second are transmitted and displayed on the monitor screen. A horizontal
frequency of 85 means that the horizontal lines that make up an image are transmitted 85000
times per second. The horizontal frequency is indicated in 85kHz.
Vertical Frequency
One image is made of numerous horizontal lines. The vertical frequency is measured in Hz
and represents how many images can be created per second by those horizontal lines. A
vertical frequency of 60 means that an image is transmitted 60 times per second. The vertical
frequency is also called "refresh rate" and affects screen flicker.
