Supported Video Display Formats
For best results, your computer's monitor port or video card resolution should be set to display in the
projector's native resolution. However, your projector includes Epson's SizeWise chip that supports other
computer display resolutions, so your image will be resized to fit automatically.
Your computer's monitor port or video card refresh rate (vertical frequency) must be compatible with the
projector. (See your computer or video card manual for details.)
The table here lists the compatible refresh rate and resolution for each compatible video display format.
