Hi, I just had to do a factory reset to my PC because I was having some problems with it, ever since I done that reset I can't seem to get my 4k monitor to work correctly. I'm using the DisplayPort which came with the monitor. (http://www.samsung.com/us/computer/monitors/LU28D590DS/ZA) it will only allow me to go up to 3200 x 1800 resolution as shown in the picture: (http://gyazo.com/f834c88b5df9381133eb865c179a8533) I'm not sure if it's something to do with CCC (Catalyst Control Centre) but I can't seem to get it to 4k resolution. Please help.
