A friend of mine has been having a problem with his resolution, he wants 1680x1050 on his Samsung sm 226bw but the biggest res he go upto is 1600x1200. The gfx is a hd5770 and he's installed the latest drivers but it hasn't solved the problem, he used to do something before to get 1680x1050 but he's forgotten.
Any help is greatly appreciated.
