multi monitor .. obtaining full resolution with r9 270x card

Question asked by vivian on Sep 15, 2015

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!
