When I update my Iris Xe graphics driver past 22.214.171.1241, 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 126.96.36.1991 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.
