(B) To set to a standard preset for the RX:
Note:
If the Manual option is not selected in Step 1, the RX automatically goes to the Manual option
when the utility is opened or when either the Apply or the Save button in the utility is selected. (If the
Save button is selected, the Manual option persists when power is cycled on the RX.) The Manual
option remains selected until the Scaling button on the RX is pressed to activate another option.
1.
Press the Scaling button on the RX once or twice (depends on the current selection) until the Manual
LED illuminates green.
2. Open the Scaler Override utility (it automatically queries the destination device for EDID
information). The EDID Status section indicates either that the EDID information has been found for
the detected device or that a list of standard resolutions is available).
3.
Under Aspect Ratio, click either Maintain Aspect Ratio or Stretch to Fit (for descriptions of both, see
page 44).
4. Under Resolution Source, click Standard.
5. Under Standard Presets, select the timing mode from the Timing Mode list and select the resolution
from the Available Display Modes list.
6.
Click Apply to transmit the selected information to the RX. This action is temporary (and you can
still cycle through the Scaling options) until the settings are stored on the RX in Step 8; otherwise, the
settings last only until power is cycled. The display re-syncs with the module.
7.
Verify that the display is satisfactory before proceeding.
8.
Click Save* to store the currently displayed settings (if the setting have been changed since clicking
Apply, the newest settings will be saved) on the RX and persist them in memory. (The RX will power
up in the Manual option.)
* If you click Close instead of Save immediately after applying settings, the utility asks if you want to
save prior to exiting. Selecting Yes applies the settings, persists them on the RX, persists the Manual
mode on the RX over power cycles, and closes the utility. Selecting No closes the utility; the applied
settings are still in effect and can be accessed under the Manual option. However, they are not stored on
the RX and on power cycle, the RX will revert to its previously stored settings.
