everything was going great until I started watching HD video, it's like the people move slower or something, weird looking.

The guy said it will handled HD video and the res is 1080p...What the hay!

I might be stuck with this thing😡

I got the 27 inch no retina and it blows the basic 21' out the water. No lag at all

I do not see how even the crappiest iMac is chocking on playing the HD video when a 2-3 years old iPhone/iPad or $300 best buy crap PC can play it just fine? there has to be something else wrong with your system in my opinion.
