Why did you have to make a custom resolution if your TV supports 4K?
Create a 2560x1440 scaled resolution. That will make a 1280x720 HiDPI resolution. The 2560x1440 will be scaled up to 3840x2160, or whatever resolution you choose as the Scaled resolutions base.
Thanks! My TV didn't accept the standard options. Had huge issues figuring out the correct timing for 60Hz to work.
Update: It works, but the image is much sharper on Windows with the same scaling. Is there a fix for this, or just a limitation of Mac OS?
