So if you say the BIOS update revealed a mainboard flaw in your case, I wonder what the recourse is for those like me who do like the machine, but have not/will not update the BIOS since everything is working now.  If DELL is not seeing the BIOS update as the issue, am I stuck on version 1.0.6 forever?

Dell is seeing the BIOS update as an issue and there are various reports on this thread of people (including me) who have been in touch with Dell support who told them they were working on an update (with no ETA).

So once the update is released and confirmed to fix the issue, you can safely update.

Hello everybody,

I communicated a little with the Dell Level 3 Support and was sent a Dell USB-C to HDMI.

This adapter works with the latest BIOS 1.0.11 without any problems, any combination with AC or without AC everything works perfectly.

Of course, this raises the question for me why do these third-party adapters only work if you feel like it?

Why is alternate mode so difficult to implement?

Long talk short story.

With this Dell adapter I was given a solution that worked for me. maybe there is also the possibility for you to get a Dell adapter as a solution.

In summary I am on BIOS version 1.0.11 and all functions like USB-C to HDMI work.

I also think that the Dell USB-C to DisplayPort on the XPS 13 9300 works properly.

Ask the support if he will send you an adapter for testing of course as a solution for free.

This "solution" is only a workaround though. 

 

First, of course it should work with any other adapters as it's even working on much cheaper machines.

 

Second, people already spent literally hundreds of $$ on adapters. 

Third - it's nice to be able to use not-so-expensive docking powert-through stations saving one thunderbolt port. 

 

It should just work... otherwise it's a faulty machine, can't see it any other way really 😕

The main difference is that the XPS 15 has one non-Thunderbolt USB-C port, which does work as expected with my DP 1.2 monitor, but the issues with the Thunderbolt ports sound exactly like what I'm seeing in this thread.

Dell released a new bios this morning, v. 1.1.0.

I was under the impression that this issue was being worked on and fixed for the next bios update, but most display adapters do not work or only SOMETIMES work. It's disappointing to see this issue not fixed, especially as so many of us are working at home with docking stations.

@DELL-Cares can you please advise us on what to do? Are level 3 techs looking into this? It seems like a hugely basic flaw for a laptop to have...

Well I got an answer back from the escalation path I was pursuing, and it didn't make sense.  They were talking about only being able to output 30 Hz on both new and older BIOS versions and therefore suggesting limitations on the adapters.  I replied asking whether anybody involved in that testing had actually read even the problem summary I sent them, never mind this thread, which makes it clear that the problem is adapters that stopped working completely after a BIOS update, not adapters that have reduced performance.  Still hoping to get an answer back on that.

As for BIOS 1.1.0, there's nothing in the release notes here about fixes for this.  Of course published release notes don't always include all fixes/changes, but given that one of the fixes mentioned was a security issue, it's possible that Dell fast-tracked a release to fix that problem and therefore other fixes planned for the "next release" got pushed.  But I don't have a way to know that for sure; that is purely a guess on my part.

I thought I was lucky.

On 1.0.11 and all previous versions I was able to get my Anker USB-C->HDMI adapter to output 4k/60hz relatively easily.  There were some hiccups here and there, but tweaking Ubuntu's display settings usually sorted them out and got me the correct resolution.

I just upgraded BIOS to 1.1.0 this morning and now that's broken.  My OS sees the display but the highest resolution it offers me is a bizarro 1280x800.

Ok, better update from my internal escalation path:

BIOS 1.0.10 included a new PD firmware meant to fix other issues.  That firmware added a timing delay before the Alt Mode discovery process (e.g. for DP Alt Mode).  That delay is causing some dongles to generate some extra messages that are unexpected by the system at the time they are generated, which causes the system to abort the negotiation and thus not enter into DP Alt Mode.

Originally the BIOS team had planned to roll back the PD firmware as part of the 1.1.0 update, but now that they believe they understand root cause (above), they scrapped that plan and are currently working with Texas Instruments on corrective actions.

Hello everybody,

I have installed the current BIOS for the Dell XPS 13 9300 and can not make any improvement in terms of USB-C to HDMI or DP.
All tested Ugren USB-C to HDMI do not work.
I also found that the firmware in Windows Device Manager does not yet have the correct driver due to the update. A manual search for the Windows update catalog was not successful.

My USB-C to DP from UNi continues to work without problems.

@ 144Hz
@ 240Hz


I hope that Dell sharpens here in the interest of the customer and that we are all happy again.
I can only say everyone opens a ticket and escalates the topic.
I also found that only the BIOS changes but no changes are made to the firmware of the EC and PD ports.

See the Screenshots 🙂

I need to correct myself from earlier - the new bios DOES improve this. Certain docks that did absolutely not work previously now work sometimes. It takes a lot of unplugging/replugging and trying again.... but it works sometimes!! For some reason, I have better luck with the port on the right side of the laptop compared to the left side...

Behavior is the same for me, but instability (both or one monitor dropping) starts up quickly even in instances where I can get the docks to connect on 1.1.0 - as though different devices are being selectively suspended (USB selective suspend not in power options so cant turn this off to test).

Overall the 9300 has been a mess, dynamic brightness that turns on every boot despite being disabled, battery life issues, audio effects (waves nx) getting turned on after disabling, and now it does not even work with my dock or my usb-c HDMI adapter. A portable with unreliable battery that also can't dock fails it's two primary use cases...

For me the problem is intermittent on Linux (both with a Lenovo Thinkvision monitor with built-in USB-C hub and with Dell's very own USB-C to USB, Ethernet, HDMI and VGA hub). Sometimes unplugging and plugging it back in a few times ends up working, sometimes it just freezes the laptop until restarted.

On Windows, however, the hubs seem to work alright. Might be a combination of the bad BIOS update and my newer Kernel version (updated to 5.8.1)

I'm the OP here. I sold the laptop almost two months ago in favour of another brand. It's still disheartening that I receive new email alerts every now and then... that, one, the issue hasn't been resolved three months on (and really, a simple BIOS rollback could have sufficed), and two, if not for @jphughan bringing the issue up to Dell's attention (and I believe the escalation process was far from straightforward on his end, too), I wonder if this issue would ever be resolved.

Anyway, to re-iterate, if you are experiencing this issue, there are a few adapters that are known to work (which I and others have posted on this thread earlier), so I guess as a workaround you should try getting one of those adapters in the interim.

It is really a pity. The XPS 9300 is really the best looking laptop out there. It's beautifully crafted and has a great feel, but unfortunately, that's all the good things I can say about it, especially when you take into account the price premium the XPS commands over other brands.
