Monitor irregularity?

Hello,

I plan on getting three monitors very soon for my gaming set up. I found two monitors that look identical to my untrained eye.

My question to you is, besides one monitor being 1" smaller than the other, why is the first monitor $30 more, and is this price justified?

Thanks!
