Habe mich den ganzen Abend mit 2 DELL U2713HM 27" WQHD-Bildschirmen, die an meiner AMD Radeon HD 7850 nicht mit maximaler Auflösung laufen wollen, rumgeschlagen. Ich hoffe, daß das Problem ohne Graphikkartenwechsel zu beheben ist. Am Ende blieb mir nur eine Support-Anfrage bei AMD: "Hello AMD-Team, I am running 2 DELL U2713HM 27" WQHD-Displays on an AMD Radeon HD 7800 Series Graphics Card. I am using the Dual-DVI-cables that are shipped with the DELL-TFT-display to connect the displays with the graphics card. I am using the latest Catalyst Driver 13.10 beta. My problem: it is not possible to run both displays with WQHD. i already swapped the cables to make sure it is not a cable problem. one display can be set to 2560*1440. with the newest catalyst driver the maxmimum resolution for the second display is 1980*1200. there is no possibility to force the second display to run on the maximum resolution of 2560*1440. i already tried several solutions, but none worked. my questions: 1. is it possible to run both displays with 2560*1440 over Dual-DVI? 2. if not, is it possible to run both displays with 2560*1440 over DisplayPort-cables? thanks in advance, Stefan Jelner"
