Ex70 Epson Bulbs Projecter Is Blurry On One Side Only. I Can Sharpen It On The Left And It's Blurry On The Right And Vice Versa?

Projecter is blurry on one side only. I can sharpen it on the left and it's blurry on the right and vice versa? - ex70 epson bulbs

I bought an Epson EX70 LCD projecten. If I focus clearly on one side (right side for example), then blurred the other side. If I clear the center of the two edges in'm somewhat fuzzy. Should I return it or is this normal? Blurred vision is not radical, but noticeable.
