hi, i have win 7 64bit, using a hd5770 and the latest catylyst control center, i run 2 screens, one is a hanns-g hw17a as my main display and my 32 inch murphy flat screen as a secondary for films etc, i have been trying to get my main hanns-g monitor to the reccomended resolution of 1440x900, and it goes to it, but leaves me with a black line, about an inch wide, on the right, can anyone advise me on how to stretch my screen to fit it?
