Supported graphic resolutions
The CATpro2-DVI-Audio target module basically supports every resolution that can be
transmitted through a single link interface according to the DVI specification 1.0. This
particularly applies to the pixel rate that may be between 25 and 165 MHz.
The common VESA DMT and VESA SMT timing standards therefore enable reso-
lutions between 640 × 480 pixels at 60 Hz and 1600 × 1200 pixels at 60 Hz. Accord-
ing to VESA CVT-RB, 1920 × 1200 pixels at 60 Hz can be transmitted.
Any refresh rates and resolutions can be applied within the parameters mentioned
above. It mostly depends on the graphics card, the connected monitor, the installed
device driver, and on the operating system which display modes are actually availa-
ble on the computer connected to the target module.
The image data transmitted from the computer to the target module are transferred
to the monitor of the remote user module with unchanged timing. Frequencies and
image position of the signal at the user module therefore comply with those at the
graphics card output.
NOTE: During the creation of the video signal, many graphics cards differentiate
between digital and analog output. Such graphics cards create digital image sig-
nals for the target module.
Independently of the operating system, some graphics cards therefore scale the
image to the resolution selected at the DDC switch on the target module. If neces-
sary, use the DDC switch to select the desired (native) resolution (see page 27).
Some graphics cards furthermore create digital image signals with non-standard-
ised timings. Such timings differ from the monitor’s standard to reduce the fre-
quencies of digital signals. Due to the non-standardised timing, monitors that are
connected to the user module in an analog way, might not be able to display both
image size and image position correctly.
