I've seen lists of freesync compatible monitors but they don't include the LG 25UM55-P despite it supporting displayport 1.2a. I'm looking to upgrade to the r9 290x or gtx 970 which is a difficult decision but if I know I can use freesync with the 290x then that makes things easier. As far as I know, all you need is the necessary GPU, displayport 1.2a monitor, and the driver from AMD. If so, then wouldn't my setup work? Am I missing something?
