I installed driver from Additional drivers.... AMD Radeon HD 6450

My resolution is at maximum and Catalist Control Center is working but I have AMD Unsupported hardware image on the right bottom of my screen. How can I remove it without reinstalling driver? Because the drivers from official amd site does not work.
