Selecting an Image Source
If you connected multiple image sources to the projector, such as a computer and DVD player, you may
want to switch from one image source to the other.
1. Make sure the connected image source you want to use is turned on.
2. For video image sources, insert a DVD or other video media and press its play button, if necessary.
3. Press the source search button on the remote control. Press the up or down buttons to select
the image source.
Note: If no image signal is detected, check the cable connections between the projector and the
image source.

Using Google Cast
Your projector has Google Cast, allowing you to cast content from Chromecast-enabled apps.
1. Connect your device or computer to the same wireless network as the projector.
2. Open the Chromecast-enabled app and press the Cast button.
3. Select your projector from the list of devices.
Note: By default, the name of the projector is EPSON Projector. To select another name or use a
custom name, press the settings button on the remote control and select System > About >
Device name.
The app connects and starts casting to the projector.
4. To stop casting, press the Cast button in the app and choose the disconnect option.

Image Aspect Ratio
The projector can display images in different width-to-height ratios called aspect ratios. Normally, the
input signal from your video source determines the image's aspect ratio. However, for certain images
you can change the aspect ratio to fit your screen.
