use clover for bootloader, enabled HiDPI,but can't use 3840*2160, RDM no 3840*2160 option.

anyone can help me to solve this problem?

I had this happen to me actually and the solution was to use Display Port instead of HDMI. Mac OS X doesn't support 4K over HDMI. You may have to get an external graphics card if your mobo doesn't have Display Port out.

my mobo has a DP out port, a HDMI port, a DVI port and VGA port , try use all of the port for test, no one can be success. maybe I have to buy an external card.

thanks!

Your DP should work. Your board does not have HDMI 2.0 so that is a no go regardless of OS support.

I try use RDM to add the 3840*2160 , but still can't find the resolution in it, no this option, the out port is DP.

can I via modify the clover bootloader or use the third party software to solve this problem? Is there any other better way?

I have the same mob and CPU and having problems even getting Sierra to install. Did you build with Unibeast or with Clover? If I try to install with Unibeast Clover is stuck at scanning entries. Any help would be great appreciated.

Thanks
