I have an a6-6400k APU installed on my windows 7 SP1, 64-bit, w/ITX board and 4GB RAM and a 600W power supply. I recently upgraded to a 21:9 monitor. According to the specs, the APU can achieve maximum resolution of 2560 x 1600. I am currently running AMD Catalyst version 15.7.1


When I go to Properties (Digital Flat Panel) my monitor (ACER ED347CKR) is identified with 2650x1080 maximum resolution and 75hz refresh rate.


When I try to switch to 2560x1080 from the Windows Control Panel Display i get a horizontally compressed screen with vertical black bars along the left and right. Looks awful


When I turn on "Enable GPU up-scaling / Scale image to full panel size" on Catalyst Properties (Digital Flat Panel) Windows Control Panel Display maxes out at 1920x1080. Looks better but the horizontal image is cutoff w/left and right sides as black bars


Any suggestions on how I might fix this?
