Summary: I get this horrible high-pitched whine when the monitor is in sleep mode. I hate it. I'd try to get it replaced, but the amount it'd cost me to ship it back to NCIX/Asus for a replacement and the fact that the monitor is perfect otherwise just makes me suck it up. Oh well... Oh! And also, this doesn't come with HDMI cables, and the monitor wouldn't turn on via display port until I installed my GTX 780's drivers. Just a heads up.
