where is daydream setting?

Ok..i admit.. i'm slow and missing the obvious.. but i've been looking for the daydream setting to check it out.. and have read that you have to have it on a docking station or charging for it to use/run.. but i still can't find it when plugged in when i go to Settings -> Display .. i thought it was in there but i don't see it even when plugged in.. what am I missing here?
Thanks

Jim

Daydream is available only on Android 4.2. I assume you have 4.1.1. so you have to wait

ok.. thank you.. i'm on 4.1.2.. so that would explain it thanks!!
