I had this monitor and ended up returning it. I was lucky enough to get a good panel when the QC was crap. That wasn't what bothered me, the monitor was great. I had an issue with ULMB which was never addressed. ULMB runs at 120hz and its a hard cap. The problem is most refresh rates run 1 frame higher, ie 120=121 144=145 165=166. I could get around this by creating a custom refresh rate of 119, but it bothered my OCD. Alot of my friends are buying the ViewSonic XG2703-GS. It is a great monitor and runs a little cheaper than the asus and acer. I would purchase one, but I'm waiting for the 144hz 4k expected later this year. Also, get the GSYNC, thats hands down the best feature for a monitor if you have a nvidia card.
