Turns out, I was misunderstanding what the lines around the numbers meant, because I thought they were the inner walls NOT the outer ones. I have no idea how I'd be able to tell the difference in retrospect, so I had the puzzle backwards the whole time.
Yeah, those inner walls in the monitor are really confusing. ^^; It's cool that the game lets players figure most stuff out without the need to spell everything out, but I feel that those inner walls in the monitors are one of the few elements that make things needlessly obtuse.
Oh! Thank you so much, I saw them as the inner walls too! Got very frustrated after checking each number multiple times, this has made me want to play again.
