26 Chapter 2 Testing Video Displays
To update the Format knob list automatically when a display is connected:
1. Connect the display you want to test with the DVI or HDMI connector on the generator.
(Analog outputs do not support this feature.)
2. Turn the generator off.
3. Hold down the R and ACS keys while starting the generator, until hot plug formats
displays on the LCD.
Note: The generator is now in Digital Friendly mode.
4. Turn the Format knob to choose a format. Only formats supported by the display are
listed.
5. Connect a different device to automatically update the Format knob list again.

Selecting formats manually

When testing a display that is not EDID-compliant, you must manually choose formats
from the generator that are supported by the display.
To do this:
• Identifing the type of display (composite television, component standard definition
television, component high definition television, computer equipment, or other specialty
display).
• Check the specifications of your display for supported formats.
• Learn how the format library is organized, and how formats are named (see below).
• Turn the Format knob to try formats from the appropriate format category. Try the
DMT0660 (VGA) format if you are not sure of which formats to use.
Understanding the format library
After connecting the generator with the display under test, turn generator on, and select a
video format.
This section describes how to choose a video format, from the list of formats built into the
generator, for the display you are testing. A format defines a set of video, timing and sync
parameters for a specific device or standard.
A summary of the format naming convention is provided. For a detailed description of the
naming conventions, see to “Format naming conventions” on page 56.

Organization of format library

The generator has several built-in formats to test a broad range of display types. These
formats are grouped in the following categories:
