Setup
9.4.2 Screen
These pages are for setting and testing the Screen resolution and orientation and obtaining Screen information (if available).
The Status page displays a summary of the Display Data Channel (DDC) information obtained from the screen, and the
currently Active output (either VGA or S-Video).
The Test page provides access to various test images.
Note: Changing the orientation or resolution will require a restart of the iCOMPEL.
Screen Resolutions and Timings
Some resolutions are defined in the VESA standards and can be used with almost any screen. These include 640x480,
800x600, 1024x768 and 1280x1024.
There a number of resolutions in use that have not been defined in any standard. There include the wide screen modes
1280x768 and 1360x768.
To correctly output to a screen in one of these modes requires the iCOMPEL to have detailed timing information about the
resolution.
Each model of screen often uses its own unique timing values.
Because the timing values are often unique to a screen, it is not possible to setup the iCOMPEL on one model screen and
expect the output to work on another model of screen.
Unlike desktop PCs, the iCOMPEL will not automatically update to match the screen that is plugged into it. You must
always repeat the screen setup each time the screen model is changed.
The iCOMPEL works in this way to allow VGA-over-CAT5 and other common installations to work.

The orientation determines picture orientation on the Screen. The following settings are available:
Landscape. This is the default display and will apply to most screens. It corresponds to 0 degrees of rotation.
Portrait - left edge at top. This setting corresponds to 90 degrees of rotation.
Portrait - right edge at top. This setting corresponds to 270 degrees of rotation.
Resolution
This is a list of the available screen resolutions.
The Defined By column indicates whether the mode has been provided by a specific Screen (using DDC) or is a Built In
resolution.
