The screen on my Dell ultrabook has a glossy finish like many screens do today. I've decided that I'd be better of with a matte finish and get rid of the glare on the screen.

Can anyone point to to a source, preferably in New Zealand, for a 14 inch 16:9 (308mm by 173mm) matte screen protector. Green onion do one but I cannot find one locally.

Failing being able to get one the exact right size I could trim a bigger one down to size. Any leads on one of those would be helpful too
