I have an RX570, Check your BIOS for CSM setting, depending on your brand it may either need to be enabled or disabled. I have a Gigabyte z390, in order to get all the ports to work on my card I need to DISABLE CSM support in my BIOS. Otherwise only 1 DisplayPort works. i also use the latest...

There’s no reason you would need to go from dvi to dp to hdmi. You can go straight from dvi-d to hdmi with passive adapters. You can also go from hdmi to dvd-d passively. HDMI and DVI-D share the same signaling. DVI-d is just limited to lower resolutions (bandwidth).

The card I linked above will work nativity all the way until Catalina.

Not sure about that one. this one will though. https://www.ebay.com/itm/193426011578

Is this for an Optiolex 780? I’m by no means an expert, but that machine most likely doesn’t have UEFI and getting newer AMD cards to work without UEFI can be a pain (or so I’ve read). if you want something that will drive two displays and works with High Sierra, get a cheap gt 640 (Kepler...

30 bit is 10 bit. 10 bit refers to each sub pixel (red, green, blue) thus a 10 bit RBG display is the same as a 30 bit display. Just two different ways of saying the same thing.

interesting you would say that. z390 gaming x 8700k Rx 570 10.15.2 changed smbios to Mac Pro 7,1 BUT I enabled igpu in bios compressor encodes via hardware (I’ll check version number when I have a chance) Handbrake encodes via hardware

One setup = geekbench 4 Second setup = geekbench 5 try using same geek bench for each setup. Comparing numbers between different versions of geekbench isn’t reliable nor recommended.

Make sure CSM is disabled in BIOS Make sure CsmVideoDXE is not in the UEFI drivers64 folder that resides in the EFI>EFI>Clover folder (see attached image)

Well that’s too bad. Hopefully you get it up and running. The EFI folder I shared is for a Z390 Gigabyte with IGPU and dGPU enabled. I have a nvme drive also, so support is there. Sleep/wake/shutdown/restart working RX hdmi audio working RX hdmi 2.0 4K 60hz working IGPU set as connectorless...

Our systems are very similar. I have changed serial numbers and uuids to my config.plist and attached my EFI folder. Obviously it won't have fixes for USB port limits or your wifi card BUT, I would try it and see it gets you booting with iGPU and dGPU both enabled. After that you can work on...

Is CSM disabled in your BIOS? I looked through your BIOS manual for CSM. I didn’t see any such setting. In your EFI partition: Look in EFI>Clover>Drivers64UEFI (orange box In attached photo) Remove CsmVideoDxe.EFI If it is there 10.13.6 does not require whatevergreen for your RX to work...

This is from a different board. Does your BIOS look similar to this? Reading here: https://rog.asus.com/articles/hands-on/rampage-iv-uefi-boot-installation-guide-on-windows-7-or-8/ It appears that, according to this article by ASUS, to disable secure boot on an ASUS board “other” must be...

CSM is a BIOS setting. The Compatibility Support Module (CSM) is a component of the UEFI firmware that provides legacy BIOS compatibility by emulating a BIOS environment, allowing legacy operating systems and some option ROMs that do not support UEFI to still be used. What is the model is your...

Secure boot and CSM are not the same thing.
