I used HDMI. ;) I did make an hackintosh with an HP Prodesk 600 with an i7 6700t sometime ago. I had some issues with the HD 530 graphics. Dual screens wouldn't work that well and hot plugging in a second display would cause the system to reboot.
Even I have the same problem with the UHD 630 on 10.15.4. Everything worked fine on 10.15.3. I use a Dell Optiplex 3070 micro desktop with an Intel i5 9500T. Turning off and on the monitor makes it work again. Unplugging and plugging back the HDMI cord makes monitor work again.
One recommendation before starting is that you try and patch your dsdt in windows using the DSDT Editor. Also if you don't know how to patch it, upload it to this forum and someone will help you fix it by modifying it for you.
Its possible. Make sure you set your bios to boot from UEFI and disable secure boot. Also if you installed win 10 first, go to your windows 10 disk manager and resize the hdd. Also make sure that your hdd is using the gpt/guid partition table.
Try tapping pin 20 of your card. This will help you to detect wifi networks and connect to them. Your system controls the wifi radio through pin 20. Tapping it allows the wifi to be always on the on state.
It stops over there because it cannot mount your drive. First set your BIOS to AHCI mode and if you are installing from usb then type this command.
and make sure that you plugged your usb drive in the usb 2.0 slot.
For the graphics to work You need not use a kext.
Type GraphicsEnabler=yes before booting the system.
If this works, then you add this string to the boot.plist file.
Use the Kext attached below for the wireless card and bluetooth.
Atheros AR5B195 pack.zip
Also for the audio driver use tonymac's...
That no smoking sign is caused by some kind of hardware incompatibility. Have you enabled the hd3000 graphics from the bios? because the nvidia graphic card causes some problems in the installation. Did you set your BIOS to ACHI mode? Also remember that this no smoking symbol means Still waiting...
