I have the R9 270x card and am running 3 dell U2713hm monitors. Max resolution on these monitors is 2560x1440.
I have 2 of the monitors connected dual DVI-D cables and the 3rd with Highspeed HDMI. All 3 work however I can only obtain 1920x1080 resolution on the 3rd (connected by HDMI) I have verified I can get full resolution on the 3rd monitor by re configuring connections .. therefore I know it's not a monitor issue. Is it possible to connect all 3 to get max resolution on all? Would a hub achieve this? I do gaming and at times would like to extend the game play across all 3 but I also want to be able to run them individually with different applications, just depending on what I'm doing at the time.
Any help appreciated!
