I have a problem with my new Monitor and my R9 290X. Its not poissible for me getting the desired resolution 2560x1440.


System Specs are:

Gigabyte Radeon R9 290X

Monitor DELL U2715H

Winodws 7 Professional 64bit

Radeon Software Crimson Edition 15.11


System Setup:

R9 290X - DVI to HDMI adapter - HDMI cable - U2715H


The maximum resolution I can configure is: 2048x1152. But the native resolution of the Monitor is: 2560x1440.


The strange thing is: when I boot an actual Ubuntu on this machine with Nouveau driver I can directly set the resolution of 2560x1440. When I switch to AMD fglrx driver then the resolution is also limited to 2048x1152. Thats strange?


So the cabling seems to fine, but the software doesnt let me configure the correct resoltion. It seems to me that there could be a proble with the Radeon Software/Driver? Or am I missing a special configuration for this?
