SmartBoard - Epson projector not projecting correctly image too wide

[speckytecky]

We have a SmartBoard 680 in a classroom with an Epson projector that's circa 3 years old - one with the big bulbous lens. Last term it was connected to a widescreen Toshiba laptop and the image mirrored was a pretty good fit. Replaced the Toshiba yesterday with a Windows 7 Lenovo desktop Think Centre with a Phillips square shaped 19 inch monitor connected to monitor and SmartBoard through a powered VGA splitter. Now the image is far too wide - more like a Landscape image and the useful bits of the Desktop are off the board. I can't figure out how to resolve this one. Had a similar problem with another Windows 7 computer and SmartBoard but resolved that one by replacing the 19 inch widescreen monitor with a square one?

Ensure graphics options and panel fit are set to normal i think.
