My biggest gripe with the 6900XT. The Lack of Display Connectors.
Comming form a RTX 2080 Ti I had 3 Monitors, one Drawing Display, a TV and my Valve Index connected.
Now with the the 6900XT I only have 2 Monitors, the TV and the Index connected because I cannot get the Multi-Display Displayport Adapter to work.

Yeah I had issues with the usb-c on my 6800XT, couldn't get either my Rift or my TV's 5.1 sound from it until I finally got the 5.1 working on my third adapter haha. Great when it works but if AMD had thrown at least one more dp/hdmi on there it would have been much simpler.

just use a old gpu to these monitors.

thats why i have a 5600xt and hd5770

How many have an old gpu just lying around these days?

I’ve done the same with my Vega 64 and FirePro W4100 in the past. Works fine.

That there are many 6900XT out there is just a plain lie xD

Cant find stock anywhere. And it took me almost a month to get one wich isnt Scalped. So yeah. Choise isnt really a thing here.

question regarding the USB-C, what can you do with it on windows? can it work as a regular USB-C too, or just display/audio?

ID: grxbliv

You can do everything with it.

I use it with a KVM.

PC -> USB-C cable -> KVM -> mouse, keyboard, headset monitor etc...

This way I only use one cable and can switch between my work laptop and gaming PC.

sweet, so a fully functional USB-C, nice since i dont have enough USB-As on my PC anyway for all the stuff i use i might get a hub/switch for it 😀

What's a kvm?

Wait what benefit will this bring? The basic usage to output a video signal is working already.

They should first fix the driver for windows... Using a USB-C KVM (switching while the PC is on) results in black screen until I replug the cable. Only works when I turn PC of before switching (standby also works).

Also changing the resolution of my monitor (from 32:9 to 16:9) is not recognised until I replug the cable.

Neither my old 2070S nor my work Laptop with USB-C have this issue. So this is definitely an AMD issue.

The Linux and Windows teams are completely unique

May not do anything, but have you reported the bug?

ID: gry11ok

Yes in all new versions so far...

There was an additional issue about intermediate blackscreen when reconnecting the cable which got fixed because it affected a lot of Samsung C9 users.

Nah, they prioritize the 0.9% OS over everything else. It's sad, really - imagine how great their GPUs could be if they cared about their customers...
