U4025QW, discrepancy between DDM and drivers website (M3T103 vs M3T102)

I see the October 21, 2024 M3T103 Windows OS firmware on the U4025QW Drivers & Downloads page.

Do not install the monitor firmware "through" DDM. Use the following instructions =

FAQ Monitor firmware

Hi Chris,

I guess the other issue is that this pop up comes up even though the firmware verison is optional and not critical. If I had my way, I wouldnt' update it to this version unless it were important. That being said, I factory reset my monitor in hopes that it would remove this pop up and black screen everytime I wake my monitor, but it didn't, so I'm now forced to do this update.

Looking at the instructions on that link you paged which was made by your community moderator, at the part where it explains connectivity, I get a bit confused and need clarity as soon as possible so I don't risk bricking my monitor.

I have my DP cable connected directly to my GPU also via DP. However, in the instructions it mentioned the below connectivity:

* PC to Monitor cables, three possible configurations =
- USB-C to USB-C video + data cable
- DP to DP video cable + USB-B to USB-A upstream cable
- HDMI to HDMI video cable + USB-B to USB-A upstream cable

This monitor does not have a USB-B port cable so I can't do any of these. The only connections I can do are the following:

- DP to DP + USB C to USB C 

- USB C to USB C Video

and of course, there's HDMI, RJ-45 and USB A ports on my monitor.

Based on the connectivity of my Dells monitor ports, can you please guide me on what cables should be connected and to where before running this firmware update. There is no clear instruction on this for my monitor anywhere online, the monitors own firmware guide doesn't mention the stuff explained in the guide you sent.

Thanks in return.

First, what PC model? What specific GPU model? List all of the GPU video out ports.

Hi,

I have a custom built PC which has the Gigabyte GeForce RTX 3080 Ti EAGLE 12GB Graphics Card. Do you need to know the other components as well?

The GPU has the following ports:

x3 DP and x2 HDMI ports

I have a macbook pro and dell laptop that I can resort too of needed.

Might be easier running the firmware update with laptop that has TB/USB-C port. You then only need that single TB4 to TB4 cable connected to the laptop and the U4025QW #6 TB 4 upstream video + data port. Note, disconnect the Desktop PC cables from the U4025QW if running the firmware update from a Laptop.

Hi Chris,

The update failed unfortunately, here's the steps I took with screenshots and logs. The following is how I connected to the laptop and monitor:

And this the thunderbolt software on the laptop demonstrating there is TB cable:

I ran the update utility as administrator and got the following:

And the monitor shows this:

I checked the directory of the folder `C:\Dell\firmware\U4025QW` and a log file was created called `U4025QW_8XHNG34_ISPLog.txt`:

```

```

In the log folder there are also verbose logs, but I don't know where to paste those since it's 700+ lines.

Troubleshooting I tried:

1) Turn off, unplug the power, and turn back on to try running it again

2) Running as admin

3) Checking if it firmware installer has read permission (it does)

I don't know what else to try / do?

I forgot to mention, I even disabled all AV software, and unnecessary background processes as advised in the instructions, as you can see below, nothing is running on my PC other than default software:

I ran the update on the Dell Precision 7680 multiple times.

I used this as a reference (Dell UltraSharp 40 Curved Thunderbolt™ Hub Monitor - U4025QW | Dell UK), so according to this, I've connected it to #6, which is the number you stated as well:

So that would be 6. Thunderbolt™ 4 upstream port (up to 140W EPR [11])

That should have worked. Maybe another U4025QW users will reply with their opinions. At this point you have two choices =

* Contact GHN chat, give them the private Service Tag, verify ownership, etc. Show them the troubleshooting and get an exchange

-or-

* Wait for a new firmware update to be posted and try it

i also just wanna add that i have the same problem. 
I even tried from update FW from different devices with different OS (Windows, MAC)
