diepnt Posted February 23, 2020 Share Posted February 23, 2020 Hi, I'm using Dell E7440. Everything works fine but only the external monitor does not work with the full resolution. It is 2k 1440p but in the setting of macOS only shows 1080p as the highest resolution. Any idea? I'm using lilu and whatevergreen. I also attached my EFI. Thank you.

Administrators Hervé Posted February 23, 2020 Administrators Share Posted February 23, 2020 "nk" terminology refer to horizontal resolutions so "2k" refers to a resolution of 1920x1080, aka "Full HD". If your monitor is "2k", 1080p will be the best you can get. 2560x1440/1440p is "2.5k"... You've activated WEG boot parameter -cdfon but I see no enable-hdmi20 property injection in your Clover config. I would suggest you add that, I believe it's expected. If 1440p resolution remains natively unsupported/unavailable, try SwitchResX app. 1 Link to comment Share on other sites More sharing options...
diepnt Posted February 23, 2020 Author Share Posted February 23, 2020 Thank you. I've enabled hdmi20 but the same result. with SwitchResX I can choose 1440p resolution but the quality is so bad. In windows 10, I can see the external monitor with 1440p with good quality. Do you have any idea? Link to comment Share on other sites More sharing options...
