Why do my reference images in 3ds max come out blurry when I

[Hill]

For some reason, when I place a reference material on a plane in 3ds max 2010, it comes up fuzzy. I made the plane the exact height and width of the image, and it still comes out fuzzy. If anyone can point me to a very detailed tutorial or maybe some answers to why this is happening, it would be much appreciated. Thank-you!
