The best way is to remove first the driver by going to your control panel, programs/uninstall a program. Go to your AMD Catalyst Install Manager and remove it. You can download the latest driver at http://www.amd.com
The HD 7770 has DP 1.2 spec so technically is capable of driving up to 4x 1080p displays from the DP port. Please note that some products can differ a bit from the standard discreet graphics card and the vendor can change this for specific reasons.
