The TV output interface is in a standard NTSC compatible format. The connector J1 can
accommodate either a standard composite signal connector (typically an RCA type connector), or
an S-Video DIN connector. Both of these connectors are on the VersaLogic CBL-1010 interface
cable.
The NTSC format is a low resolution format intended for non-GUI uses. Selected VGA screen
resolutions above the NTSC resolution of about 512 x 350 (depending on the quality of the video
monitor) will tend to look fuzzy on the TV monitor. The video chip on this board scales the
selected VGA resolution to the NTSC resolution format. When scaling from a higher resolution
(such as the default 800 x 600 Windows format) to the lower NTSC format, much of the video
information is lost, resulting in a hard to read screen. Even the standard DOS level video format
of 640 x 480 will show some image degradation due to the scaling. Crisp TV Output can only be
obtained when scaling from a lower VGA resolution, such as 320 x 200.
