Can I run USB Display and Easy Interactive Tools (EIT) at the same time?
You can run the USB Display and Easy Interactive Tools at the same time. Open the projector's Extended menu and set the USB Type B option to USB Display/Easy Interactive Function. Also, a USB 2.0 connection is recommended for better picture quality.
Epson recommends using an HDMI or a VGA connection to project your computer's image when using the interactive pens. Using other types of connections to project your image, such as USB Display or a wireless connection, may cause your pens to not work properly (e.g., the pens may lag or skip).Related references
