I just bought this monitor on the 27th from Acer Outlet as a refurb for $399.99, today Acer released a firmware update for the OD issue with FreeSync.
Update 2nd July 2015 - Acer have confirmed a firmware update has now been made available to their service teams to address any issues people are facing with the activation of overdrive with FreeSync systems. The following statement was provided to us: "Customer service and experience are priorities for Acer. Customers owning an Acer XG270HU Monitor may potentially experience slower response times when connected over DisplayPort to FreeSync compatible graphic cards of the PC. When connecting to PCs with other graphic cards or connection options there is no impact on the performance and response time. Customers which believe they are experiencing a potentially slower response time than normal, may contact the nearest Acer Service Center for a firmware update."
I am wondering what I can do here, as I am using FreeSync and got the monitor specifically for that, but I have no idea if the monitor has already been updated as I just recieved it today, and I don't see any way to check the firmware myself, and I really don't want to have to send it off when I just got it today, but as I play a lot of shooters, that slow response time can be crucial.
It has a 90 day manufacturer warranty, and I suppose I can take it to an Acer service center and have them do it? But I don't see any concrete listings on the Acer site to find such a center, and how much it would cost, if anything since under warranty. I am in Springfield, MO.
Any help would be greatly appreciated.
