INPUT COMPATIBILITY
The IN1776QZX will work with video signals from PC compatible computers and the
Macintosh family of computers as follows:
VGA / SVGA / XGA
Resolutions: 640 x 480
800 x 600
1024 x 768
Vertical Refresh Rate: 50 to 100 Hz
MAC II / Quadra / Centris / Performa / Power Book / Power MAC
Resolutions: 512 x 384 (12” Color Monitor)
640 x 480 (13”/14” Color Monitor or Multiple Scan)
Vertical Refresh Rate: 50 to 100 Hz
Other Signals
The IN1776QZX automatically senses the characteristics of the input signal and adjusts itself
accordingly. This allows it to work with non-standard signals which fall within its operating
range. For instance, while standard VGA signals are 640 x 480 resolution / 60 Hz / 31.5 KHz in
the RGBHV format, the IN1776QZX will also accept a 640 x 480 / 60 Hz / 31.5 KHz signal in
the RGBS format. The main limiting factor for compatibility is not the vertical scan rates or
sync format, but the video resolution which must not exceed 1024 x 768 and the horizontal
scan rate which must not exceed 66 KHz.
Using an optional input adapter, the IN1776QZX may also accept signals other than the VGA
and MAC standards listed above as long as they fall within the following operating parameters:
Resolution:
512 x 384, 640 x 400, 640 x 480, 800 x 600, 823 x 624, 1024 x 768
Horizontal Scan Rate: 24 KHz - 66 KHz
Vertical Refresh Rate: Up to 100 Hz
RGB Video Signals: Analog Video, 0.7 Vp-p
Sync Signals: Composite Sync or Separate (H & V) Sync
OUTPUT COMPATIBILITY
The IN1776QZX output signal may be connected to many types of video equipment including
TV & presentation monitors, video projectors, VCRs and teleconferencing equipment. Video
output is offered in three formats:
Composite Video - Offers the widest compatibility with consumer video equipment such as TV
monitors, VCRs and other equipment with composite video input.
S-Video - Also known as Y/C, this output provides a clearer signal than the composite video
output and should be used whenever possible. S-Video may be connected to any video
equipment having an S-Video input such as video monitors, large screen monitors, video
projectors, and S-VHS and Hi-8 VCRs.
RGBS - This output provides the best clarity and color accuracy and should be used if your
display equipment has an RGBS input. This format is most frequently used with industrial and
professional grade video projectors, RGB monitors and retro-projectors.
