I have a MacMini running Windows and it is using the IntelIris 5100 Graphics card. I have installed the latest drivers (version 18.104.22.16826). The maximum resolution I can choose is 2560x1440 (higher doesn't work). I went through the forum and found a way on how to create a custom resolution. I have created the 2560 x 1080 (60Hz and 59 Hz). They show up in the list with custom made resolutions.
Then I want to select them and they do not appear in the list. I have tried all settings but the new custom resolution I created does not show up. Is it possible 21:9 is not supported?
