It is true 3070 has DP and HDMI output is available.  HP monitor has DP and DVI input, and I can get a smooth image directly via DP.  but for the hdmi connection, I am using the hdmi to dvi adapter. HDMI connection at OSX, the image disappears at the login screen, plug out then plug in the login screen appearing. I can't get the image in OS X at home netiher DVi to Hdmi nor hdmi cable.

Hi @Jake Lo,

I copied the config.plist file to usb flash and booted with it.  I tried from both DP (with DP to hdmi adapter) and HDMI output, but when it came to the login screen, I couldn't get an image. DP and hdmi output works oob with win 10.  I will send ioreg files with HP monitor at work tomorrow. Thanks.
