I have AMD HD 5770 card connected to 2 identical DELL 2719DGF monitors via DVI to HDMI cables. Each monitor supports 2560 x 1440 resolution, however I'm not able to set the extended display resolution in WIndows 7 above 1920 x 1080. The card spec shows the maximum resolution supported to be 2560 x 1600,
Please explain how can I achieve the best resolution given in the specs.
Thank you in advance !
