Doremi DSDI-20s - Manual (Page 8)

Note: According to the input(s)/output(s) available for each device, the OSD menus and remote
controller functions might not all be active for each device. For example, no SDI input setting will
be possible for the DSDI-20 device.
For clarity in this document, the OSD and remote controller functions are presented in their
entirety, while active functions might differ from one device to another.
Please refer to the table above to identify which function is applicable to each device.
2.3 DVI20-Devices Operation
On power up, the DVI20-Devices will automatically detect the input format of the selected input
and will send a message to the monitor connected via DVI requesting its EDID parameters. The
EDID parameters of the connected monitor will be used by the DVI20-Devices to determine its
output resolution.
The DVI20-Devices DVI-D output has 2 major controls: Resolution and Frequency.
Resolution:
Can be set to Auto (default) or forced to 1024x768, 1280x720, 1280x768, 1280x1024, 1366x768,
1400x1050, 1920x1080, 1920x1200 or 1080i
Frequency:
Can be set to 48Hz, 50Hz, 60Hz (default) or forced to Frame Sync.
2.3.1 Resolution
The output resolution can be set to Auto, 1024x768, 1280x720, 1280x768, 1280x1024,
1366x768, 1400x1050, 1920x1080, 1920x1200 or 1080i, using the On Screen Display (OSD). In
Auto mode, the output resolution will be set to match the monitor up to 1920x1200.
 If the EDID response of the monitor is not recognized or is higher than
1920x1200, the DVI20-Device will default to 1280x1024. In the case where this
same monitor does not support 1280x1024, the output resolution can bet forced
using the infrared remote control and without the OSD interface by using the
remote control DVI out selection.
 If the DVI20-Device DVI output is connected to a consumer TV that reports 1920x1080
interlaced, the unit will default to output 1080i.
 In case of a TV set that reports 1080i, the HDVI-20 device will output a compliant 1080i
signal and the TV will display it properly.
 XDVI-20 only:
The XDVI-20s cannot display both DVI-D and SDI at the same time - use the remote
control DVI out or SDI out selection.
Note: In case the selection is for SDI out, the displayed DVI output is not valid.
2.3.2 Frequency
The default frequency is 60Hz because it works with all displays. If your display supports lower
frequencies and if your input source is running at 24/48, 25/50 Frames/Fields per second, you
can avoid motion artifacts by forcing the output frequency to Frame Sync.
