Hello,
When I update my Iris Xe graphics driver past 30.0.101.1631, I am no longer able to run my external monitor at 3440x1440 60hz, the highest resolution I can select is 2560x1080 60hz.
Once I downgrade to 30.0.101.1631 or anything below in the 30.0.101.XXXX range, it will start working again.
Here is my setup information:
Model: Framework Laptop
Processor: 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz
RAM: 16.0 GB (15.8 usable)
OS: Windows 11 Pro 22H2 (22621.819 Windows Feature Experience Pack 1000.22636.1000.0)
Dock: Pluggable P/N UD-CAM (https://plugable.com/products/ud-cam)
Monitor: ASUS VG34VQL1B
This might be more of a bug report than a question, but I am curious to see if there is potentially anything wrong with my setup that is causing the issue with the new updates.

Please contact the manufacturer of your Dock device to get a firmware update. It can be then done in Windows.
It helped me to fix 1080p issue with adapter cables Thunderbolt > HDMI:
I didn't know before that you could even flash a cable. But this 1080p issue seems to be related to a bug in particular chip-firmware in the cable. To me it seems that the combination of this cable bug combined with another bug in older Intel drivers did only allow the higher resolution coincidentally, but it's not a solution to revert Intel drivers back to this condition.
Quote for my cable:
- "1080p resolution lock on 11th generation Intel systems. The firmware update resolves an issue that locked 11th generation Intel systems to a maximum resolution of 1080p@60Hz."

Thank you for your recommendation- I've reached out to Pluggable to see if they know anything. They did not have firmware available on their site, but I did download and install the driver. Unfortunately, it still will not work- for now I will just keep downgrading my driver every time it updates while I wait for Pluggable to respond.

Hello,
Just a check-in: more than 2 years later and this is still an issue. I had a newer driver versions working on different docks but with the newest updates they broke again. Seems like every update is removing features, which is disappointing. I even updated to 13th gen processor and am still having the same issues.

Good that you got in touch again. I have recalculated your case. Summary:
Monitor: VG34V Series, 3440 x 1440 (UWQHD) @ 165Hz, 2 x HDMI 2.0, 2 x DisplayPort 1.4
Docking Station PLUGABLE "UD-CAM": 1 x HDMI 1.4
Quote: "Drive a single HDMI display output at a maximum resolution of 4K 30Hz (2560x1600 and lower at 60Hz) on compatible USB-C Alt Mode systems."
--> 2560 x 1600 @ 60 Hz Coordinated Video Timing - Reduced Blanking (CVT-RB) = 8.1 Gbps
Framework Laptop with USB-C Expansion Card (FRACCCBZ01). Is this correct?
-------
(1) 3440 x 1440 @ 60 Hz CVT-RB = 9.54 Gbps
(2) 3440 x 1440 @ 165 Hz CVT-RB = 27.72 Gbps
If certain graphics driver versions work with (1), then that is outside specification and an unintentional accident.
If you swap the dock for the UD-MSTHDC model and connect the monitor via DisplayPort, the full resolution and refresh rate (2) of the monitor should be usable.
