Lost some screen resolution on Amd R7 265

Please help me solve this problem
so lost some resolution in-game after changing video cards and drivers that were previously was the hd 6870 and the old driver was changed to R7 265 2gb, and put the latest at the time the driver 18.6.1 Crimson
the monitor has a max resolution of 1680x1050, up to 1280-1024 lost all
before there were 1366-768. 1400-1050, 1440-900, 1600-900
now they are not only the native monitor 1680-1050 and below 1280-1024
Windows seven 64, the other Windows 32 and old driver is not only 1600-900
and 1400-1050, the rest is all there what a joke I do not understand
before with the old card was absolutely all permissions, anyone knows tell me what the problem is!
