Is this monitor IPS and does it support VESA? http://www.ebay.com/itm/X-star-DP2750QHD-27-LED-HDMI-2560x1440-Anti-Glare-Monitor-/322056729808?hash=item4afc13b4d0:g:MLsAAOSwJQdW-1UN
It doesn't say IPS anywhere in their marketing, and that is a selling point, so my guess is no, not an IPS...
As for VESA - 100x100... There is a picture in your link, that is even showing the VESA mount.
