3 HDVI-20d Operation

On power up, the HDVI-20d 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 HDVI-20d to determine its output

The HDVI-20d's 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

Can be set to 48Hz, 50Hz, 60Hz (default) or forced to Frame Sync.

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

HDVI-20d 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 TV/Video + Number combination according to the

following table:

o TV/Video + 0 => Auto Mode

o TV/Video + 1 => 1024x768

o TV/Video + 2 => 1280x720

o TV/Video + 3 => 1280x768

o TV/Video + 4 => 1280x1024

o TV/Video + 5 => 1366x768

o TV/Video + 6 => 1400x1050

o TV/Video + 7 => 1920x1080

o TV/Video + 8 => 1920x1200

o TV/Video + 9 => 1080i

• In case of a TV set that reports 1080i, the HDVI-20d will output a compliant 1080i signal

and the TV will display it properly.

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.
