DVI Video Data Transfer
When the display runs with its standard resolution, it will decode each of the numbers and will apply the
needed brightness to the corresponding pixel. And because of this method, every pixel from the output buffer
of the device source corresponds straight to one pixel in de digital display. Whereas with the analog signal
the appearance of every pixel can be affected by its nearest pixels and by analog distortion and some
electrical noise.
DVI connector includes pins directly for the display data channel, the same as VGA or SVGA connectors,
and this allows the graphics adapter to decode the extended display identification data of the monitor.
Usually, the cable lenght can be up to 4 meters and can display resolutions of 1920 x 1200. Longer cables can
be used, up to 15 meters, but the display resolution will decrease, because of signal loss. However, if a DVI
booster will be used, the lenght of cable can be even higher, and without any loss in resolution.
These DVI boosters can have an external power source.
