I am looking for a 144hz 2K IPS monitor (unsuccessfully I may add since my budget is $600 and both the mg279q and the xf270hu are wrought with quality control complaints) but on bestbuy.com they just posted a "new model" monitor which is the acer XF270HUA. I assumed the A was just a typo but then I googled the UPC number and it yielded no results, and no such a monitor exists on the Acer site. Any ideas on what's going on with this monitor?
