Sorry, but this is simply bad advice, they're TN screens 1080p panels, we're in 2016, I have no problem with TN screens inherently, I mean my favourite monitor was a Samsung 23" 120HZ TN, but that was leaps and bounds better than the asus linked here (And I had my Samsung from like 2012-2014).
You've got a habit of professing your personal slanted opinions on others and it's wrong.
OP, 21:9 might be your best bet if it's something you're after, something with Freesync/Gsync. We are after all, in 2016, or go for 3 1080p IPS/VA panels (Heck, you could even get Freesync screens)
