VBR – Variable Bit Rate
A ‘bit’ is a single piece of digital data. This data is compressed so that you can record more on a single disc. The Variable Bit Rate continuously controls the amount of compression for a more efficient recording.
Velocity Modulation
Regulates the speed of the electron beam to keep the picture tightly focused at all times.
Vertical Aperture Control
Senses and adjusts brightness in the vertical plane.
VESA mount
With this, you can mount a monitor on a desk or wall. It meets recommendations of the Video Electronics Standards Association (VESA).
VFZ (Vector Format for Zooming)
This next-generation digital image format uses lossless compression to save an image at 2/3 its original size. Unlike standard digital compression, which makes it difficult to reuse data, this format allows the easy enlarging and reducing of data, with no loss in quality.
VGA (Video Graphics Array)
A graphics system developed by IBM. Resolution is 640 x 480 pixels and uses 16 colours. Widely used as a standard for PC graphics systems.
VGA Connection
15 pin analogue video only connection found on many desktops and laptops, and LCD/Plasma TVs.
VGA input (TV)
VGA input lets you connect your PC – effectively turning your TV into a PC monitor.
Viewing angle
It’s the degree of angle at which you can view the screen from the sides (horizontal angle) and top/bottom (vertical angle) and continue to see clearly defined images and accurate colours.
Virus
A piece of code which infects a program on your PC and then replicates itself and moves on to another machine. At the same time, it might delete data from your machine, or use your PC when you’re not looking to send out spam emails.
