Change display options
-
Open the Emulator tab by doing one of the
following:
-
From Adobe Device Central, select File > Open, navigate to a file, and double-click the file.
-
In a supported Adobe application, open a file and select Control > Test Movie.
-
- On the Adobe Device Central Emulator tab, expand the Display panel.
- Change the following options as necessary:
- Backlight
-
The
Backlight slider lets you decrease the brightness of the backlight as
it would normally do when going into sleep mode. Some mobile device
users also purposely lower their backlight brightness to save battery
power. When designing mobile content, check if the content is visible
with low backlight. (If you change the backlight settings, the settings
stay in place as you open different devices for testing on the Emulator
tab.)Note: If the Timeout function is enabled, the Backlight slider is disabled. To enable the Backlight slider, turn the Timeout option off.
- Timeout
- Lets you automatically test the time‑out function. The default is unchecked. Checking this option enables the backlight time‑out function. In the text fields, set how many seconds before the backlight times out. The default setting is four seconds. Like on the actual device, after the backlight goes out because of inactivity on the device, it turns on again as soon as activity resumes. To ignore any time‑out settings while you test, deselect the check box again.
- Contrast
- Lets you change the display contrast to test the visual appearance of the contents under different contrast conditions. Defaults to 0 with a range of 100 to ‑100.
- Gamma
- Lets you change the display gamma to test the visual appearance of the contents with different gamma conditions. Defaults to 0 with a range of 100 to ‑100.
- Reflections
- Lets you simulate different environmental conditions in which to test the visual appearance of your content.
