4k 3840x2160 not working.

Open bs-github opened this issue 6 years ago • 0 comments

I am limited to 1080p which is half the possible resolution of my screen :-(.

As far as I can tell, this is a known problem, but I wanted to have the issue visible here and join forces to get over it. You can read more about it here: https://forum.novaspirit.com/t/lattepanda-alpha-hackintosh-mojave-intel-m3-7y30-install/369/4

I tried to read up on this topic and now I assume the pixel clock has to be patched to enable higher resolutions, but I have not gotten to the point to know how to do that (preferably with clover).

I'm not sure if 4k@60hz is possible on the on board HDMI, but I'm sure it is possible via the USB-C port.

On Windows I get 3840x2160@30hz on the HDMI port and 3840x2160@60hz with an adapter (https://www.amazon.de/dp/B078JZMR9L) on the USB-C port.

Interestingly even the lattepanda boot logo and clover itself are in 3840x2160@60hz with the adapter, but Mojave goes back to 1920x1080@60hz as it's maximum.
