Does the X113H projector support screen capture to enable the start up screen to be changed?

Use the screen capture function to customize the startup screen. To capture the image that you want to use as the startup screen, follow the instructions below.

Notice:

Before proceeding with the following steps, make sure that the "Keystone" is set to the default value 0 and the aspect ratio is set to 4:3. For details, refer to the "Image" section.

• Change the "Startup Screen" from the default setting "Acer" to "User".

• Press "Screen Capture" to customize the startup screen.
• A dialog box appears to confirm the action. Choose "Yes" to use the current image as your customized startup screen. The capture range is the red rectangular area. Choose "No" to cancel the screen capture and exit the onscreen display (OSD).

• A message appears, stating that the screen capture is in progress.

• When the screen capture is finished, the message disappears and the original display is shown.

• The customized startup screen, as shown below, takes effect when there is a new input signal or when you restart the projector.

Sorry, you are correct. After further checking, that user's guide is for a variety of products, and not all of those products support all the listed features. From what I can tell, the X113H does not support changing the startup screen. If it did, you should be able to push the setup button on the remote to make that change. Sorry for the inconvenience.
