The display options that are available 

J.2.1  System Setup 

To display the Picture images, you need: 

1.

 

Plug a suitable monitor into the HDMI output port on the 

Ultra

’s back panel. 

HDMI Output port

 

Figure J-2:

2.

 

Use the Connections window to direct the output from the Analyser/Converter block into the 

Local User Interface, and to direct the Local User Interface to the HDMI output port. 

 

Figure J-3: 

Connections needed on the Connections window to display Full-Resolution Images  

The steps needed to achieve the required result are therefore as follows: 

To display Pictures on an HDMI monitor: 

1.

 

Plug a suitable HDMI monitor into the HDMI Output port on the 

Ultra

. 

2.

 

Display the

 window. 

3.

 

Make a link from the 

Analyser/Converter

 to the lower of the two little squares on the  

right-hand-side of the 

Local User Interface

. 

4.

 

Make a link from the upper square on the 

Local User Interface

 to the 

HDMI Output

. 

 

Note

: It is not possible to take output from the Ultra’s Converter at the same time as Picture
