Driving monitor via USB info

[Ch3m1c4L]

Can someone relieve my ignorance on this concept please.
I know the port needs to support dp/hdmi via USBc, although not sure if this is standard in 3.1 or 3.2 if a c-type port?

Does the c port on my x570 Asus crosshair viii hero support it, even though I can't see it explicity mentioned on the spec sheet?

Does the host system require the use of an igpu or can it be driven via a discrete card? Or is it all just software emulation?

Is it a solution to going beyond the max monitor support of the igpu/dgpu (4?) or does it encounter the same limitations and is just a different interface, which the benefit of is simply less cabling for specific displays?

Pretty sure
It can be done by my x570 crosshair viii extreme
Not so sure about the hero
Though never tried it
Have vague recollection that's why my board
Has displayport in ports
Something to do with looping the video signal
From displayport out
To display port in
Then it sends it out over the usb c/usb4/thunderbolt ports

Never really fully read the manual
When it comes to doing it
As though my monitor does have a kvm
That has usb c
The only thing I ever use it for
Is connecting my Samsung phone and tablet
To use the monitor for Samsung dex

Newer AMD systems seem to have undocumented (at least, so far as I can find) passthrough capabilities, so with AM5 I wouldn't want to state anything 100%, but I would assume you need the IGP to use this feature.

Pretty sure it just channels the video through DP, as Mcnumpty said, so the same limitations would apply.

Gigabyte and ASRock include block diagrams for their higher-end motherboards and for the Z790 Taichi and X670E Taichi, they're shown as DP ports connected to the CPU.

Does the c port on my x570 Asus crosshair viii hero support it, even though I can't see it explicity mentioned on the spec sheet?

DP over Type-C usually comes with increased power (USB PD), but on the website they say check your I/O shield as it may have a DP logo near the port.

Thank you both. That has cleared up my confusion/understanding of what it is and how I can use it.

just read my manual
looks like 15w on the rear ports
and 60w on the front port--edit if you connect the 6 or 8 pin from psu
forgot whether its 6 pin or 8 probably 6
though cant do video off front port i think
dont have my front port connected as gpu is massive
and blocked it
but 15w on rear doesnt sound enough
to power a monitor
though can send video
must admit its pretty confusing
theres no hdmi or display port out on rear io only IN
so even though the board supports G cpus
i see no way to actually use their integrated graphics
though i am having a bit of a brain dead day i must admit

That's a bit annoying, means you have to dp from gpu to mobo, just to then usbc to monitor, but carrying no power on so at most only saving running a usb data cable to the monitor. Seems like an after thought in the design rather than allowing the 60w pd to go via rear port.

I think with these higher end boards, one isn't expected to pairing it with a low end cpu, which all apus were/are. You'd buy a cheaper board if you were buying a cheaper cpu. So it saves a little on cost I imagine.

Little annoying though when it comes to many monitors, but I guess it's niche enough that people can be expected to research/buy specific product versions. May well change in future as the range of amd cpu's with igpu's changes/increases.

i guess it may be possible
to daisy chain the video signal
through multiple usb c monitors
which would save some cables and allow more monitors
but the monitors still need their own power source
but yeah seems like a pretty niche product
i didnt pay the extreme new price for the board anyway
so didnt get it with the intent of using that ability
its still a great board though
especially since i paid somewhere around £300--350 forgot
exactly as usual lol
