Compatible Video Formats
These projectors support the high definition video and computer 
display formats listed here.
To project images output from a computer, the computer’s video card 
must be set at a refresh rate (vertical frequency) that’s compatible with 
the projector. Some images are automatically resized using Epson’s 
SizeWize
™ technology to display in the projector’s native format. The 
frequencies of some computers may not allow images to display 
correctly; see your computer’s documentation for details.
