1. Introduction
1.1 General
Thank you for purchasing Black Box Model AC551A Component
Video (YPbPr) or VGA to HDMI Converter with Audio. The AC551A
is used to connect the VGA video signal from a PC or the YPbPr signal
from a DVD player or similar device to the HDMI input of a Plasma or
LCD screen. The unit takes advantage of HDMI cable’s ability to also
embed the audio in the same signal with video.
In combination with Black Box Model SW-214A 3 input HDMI
switch, you can mix and select between new HDMI enabled devices
and legacy DVD players with Component outputs, or display your
PC’s video on the screen.
Note about HDMI compatibility with PC Video
The AC551A is not a scaler or scan converter. This means that the
resolution of the video signal at the HDMI output is the same as the
input signal. Most HDMI enabled displays do not support the full
complement of PC resolutions and are only designed to handle HDTV
input formats of (480i or 480p) @ 60 Hz, (576i or 576p) @ 50 Hz,
720p @ 60 Hz, or 1080i @ 60 Hz. This means that if you set your PC
at a resolution of 1024x768 (XGA), your display may not show the
HDMI image. In this case you have to set your PC’s resolution to either
640x480@60 (VGA interpreted as 480p), 800x600@50 (SVGA
interpreted as 576p), or 1280x720@60 (WXGA interpreted as 720p).
