Press the Return symbol or Enter button to select a setting.

Press the Menu symbol or *Menu *button to close the OSD menu.The menu will close and the projector will automatically save the new settings.

To adjust the left or right side of the picture (the yaw), turn the projector slightly left or right. If that is not possible, adjust the horizontal keystone:

Select *Image > H Keystone *

Note: horizontal keystone correction is not available on all models
