Someone from Dell reached out to me via email yesterday. They will procure a "faulty" adapter from Amazon and test if they can replicate the issue and from there forward it to the engineering team for a solution.
So far I have pointed them to a "faulty" CableCreations adapter. If you guys could list down Amazon links to incompatible adapters, that would probably be helpful too.
They reached out to me via Twitter yesterday.
I provided them a link to the adapter I have.
Hoping this is a sign a fix is on the horizon.
Hi everyone , I have the same issue, I bought a ugreen usb c to hdmi adapter at 60hz and the same problem but something weird happens because after sometime with my xps connected to the power adapter I did the test and it worked , seems like something with the power manager or something like that.
So I have tested many adapters and all adapters work on other notebooks.
the adapters worked for me before the BIOS update / the TB3 port firmware / Power firmware update or the CVE for TB ports.
I have also recently received a Level 3 escalation from Dell 🙂
I also ask everyone who finds this thread to open a Dell Support Ticket if we are to be heard.
@JayKay808 this cable works fine for me usb-c to DP from UNI.
I have now received an answer to my problem, there is a technical defect on the mainboard that has been adjusted from level 3 and the error does not occur in the lab.
So my XPS13 9300 is completely exchanged.
I hope that all customers who have this problem will get a new device
I'm returning my XPS 13 9300 back to Dell for a refund as a defective device. Customer support wouldn't offer any form of online credit or partial refund for my troubles. After pushing them pretty hard, they offered me "up to 15% off a new device", so I'll keep an eye on this thread over the coming weeks to see if the problem is resolved.
Customer support also offered me an opportunity to receive a pre-release BIOS update, but they wanted me to sign an NDA to receive it. I wasn't about to sign an NDA to get what I already paid top dollar for, so I passed, but if you're past the return window for your machine you may want to ask about it.
Add me to the list as well, bought this last night, today morning windows update and the external monitor stooped working, it was working fine before BIOS update, i have opened a support ticket as well.
Can anyone recommend a display port to type C Cable that is working fine?
