My 29" LG 29UM57 Monitor advertises 2560x1080 resolution, however the best I an get is 1920x1080 resolution; I am using HDMI to Display Port cable - my monitor has 2 (HDMI ports only), my graphics card support Display Port and DVI (only - no HDMI port) - the graphic care supports 2560x1080; It was suggest going HDMI to HDMI with a new graphic card would achieve 2560x1080 ...does this make sense?
