LG G2 Lock Screen Size

I have an LG G2, and I feel a little dumb asking this, but I have seen a G2 with the regular pattern lock screen with the dots (3×3) spanning the whole screen, but mine is much smaller (still a 3×3 but much less space between the dots), and I can't, for the life of me find a way to change this setting. And I dont think he had an app or anything. His phone was a day old, and he hadnt really used it because it didnt work correctly, so we were replacing the phone he had with a new one. Any tips??
