I want to create a custom resolution with the new drivers, as I dont want to be rely on third party applications like CRU anymore. Now, with the first attempt I failed (Picture horizontally split in half when using the custom resolution), so I need a detailed step by step Guide. The Custom resolution should be: 1280x720 with 75hz, very simple.
My Monitor: BenQ GL2450 (FHD, 60hz)
GPU: Sapphire Radeon R9 290X Tri-X OC
