Has anyone gotten DP passthrough working on the ASUS proArt x670E Wifi?

[ISE8]

Has anyone here been able to get dp passthrough working through thunderbolt on the X670E Pro Art wifi mobo?

 

I'm at wits end trying different cables and displays but the passthrough just wont work. I have a 3090 and currently have 1 monitor connected through HDMI and 1 through DP .

For my 3rd dp port on the 3090 i have the display port cable that came with my mobo connected to the "dp i:n slot in my mobo as seen in the pic below but none of the displays connected through the thunderbolt 1 port or 2 port are working. Am I doing anything wrong?

 

The strange thing is some display shows up in windows when i attach the monitor this way but I'm unable to identify it, change the resolution or chose options such as duplicate or extend. Everything is all greyed out and nothing shows up on NVidia control panel.  My thunderbolt control center also shows no device connected

 

I have the thunderbolt drivers installed from ASUS drivers sections and the latest 1807 bios

 

Current things I've tested

- 4 different USB-C monitors that work on usb-c and thunderbolt laptops

- 3 different tested and working dp cables as passthrough

- various USBC, USB4 and thunderbolt certified cables that work on laptops for display and charging on laptops

- all dps on the 3090 as passthrough

 

Is there something I'm overlooking?

What monitor is it?

Cintiq 16 pro

Asus PA147CDV

Lepow z1 gamut

 

All of these work on multiple laptops single cable both mac and an older windows one. The lepow works on usbc alone without thunderbolt

Unfortunately, i'm not really surprised. The USB/TB implementation on this generation of AM5 boards has not been great, lets just say. Little to no comprehensive coverage of it specifically, either. You've done all the right things, too. 

 

Could simplify things and just get a DP to Type C cable. Is it ok that we spent money for these features that don't work? No, not really, but that's a workaround. 

 

The Thunderbolt/USB4 ports on my X670E Taichi work for video output but they're directly tied to the iGPU, I don't have DP passthrough, and they work alright for me.

None of these are Thunderbolt, they're USB-C DP Alt mode, so it's normal they don't show up in thunderbolt control panel. 

 

Did you look at the supported configs in the manual? What CPU are you using?

Im rocking a 7950x3d

 

I have tried to the configs in the manual (use the ec1 pretty much)and have tried both ports.

Did you check for any potentially related options in the BIOS?

[ISE8]

I did, everything should be enabled in bios.  I can take a screenshot when i get home

there definitely feels like there's something wrong with the passthrough implementation after i spent the last 2 days playing with it. 

 

I upgraded to the newest thunderbolt drivers. Installed new drivers for the igpu for the 7950x.

The monitor works on usb-c  when the igpu is enabled but only in bios screen; as soon as windows loads the monitor no longer works.  I can directly connect it the the igpu hdmi and it works with my discrete 3090 but that defeats the whole purpose of why i get this motherboard.

 

Looking around theres a lot of similar asks but looks like no one has gotten any passthrough to work with the motherboard. =(

Hi Just got my Pro Art set and I must say I gave myself quite the heart-sank feeling when I got a BSOD and windows enterered REPAIR MODE!!... tried OC'ing the ram to what it's rated clock speeds are (7200) (just like I used to do on my ROG z690 wifie gaming mobo and worked fine.....)..  Restarted a few times and finally kicked back into windows at stock settings...

 

I, too am confused by the DP/TB combo thing.. I got a 3090 as well, hooked up via DP to one another, thus sacrificing 1 coveted DP for what reason? I really dont know. I dont know what the point of all of this is, to hoook up an external adapter at thundebolt speeds?? What if I have 3 monitors that ALREADY Work fine directly connected through my mobo as they have for the last year or so?? 
 

Think im just gonna go back to that configuration... This is ridiculous

To use a Thunderbolt-only monitor like the Apple ones... Mostly pointless today but for a brief period that allowed for higher resolutions/refresh than other connections.

Or to connect a Thunderbolt dock and have multiple monitors through a single cable / do a "PC in other room" setup.
