missing the tab additional setting in amd crimson display

Found the solution : i needed to create custom resolution and type the resolution i needed in horizontal rez,vertical rez,H.timing display,V.timing display.

my gpu is :

Sapphire Dual-X R9 280 OC with Boost

im using win 7 64bit

im currently using amd crimson 17.7.2

my cpu is intel core i5 4690@3.5ghz

ram 8gb

this is my motherboard i think asrock h87m pro4

powersupply should be 650w

 

i need to change my max resolution to 1920x1080 but i cant because i am currently stucked at 1600x1200

and i cant see the additional setting tab to change my vga settings
