Lost higher resolution after kernel and os upgrade

Hi everyone. I have been using Ubuntu 24.04 with X for a couple years now and successfully used my Anker docking station USB-C with two external hdmi monitors from my laptop. I was able to get 1440 resolution on both monitors. I typically did not also use the laptop screen with it, just the two external. I had one in landscape and one in portrait. It was very useful, so I bought the same docking station and setup the same configuration in my other office. Both worked reliably.
Now, by necessity I have upgraded to 26.04 with Wayland. This includes the 7.x kernel. Now, after a lot of frustration I can now use both external monitors, but I am now stuck at 1080 resolution on both. This is the same in both of my offices. This also seems to be the same regardless of OS if the newer kernels are being used. I tried Debian Trixie, I tried CachyOS, I tried MXLinux and different flavors of ubuntu. All are stuck at 1080.
So something about Wayland and/or the newest kernels is preventing me from getting dual 1440 as I once had. If I turn off one of the monitors and tell whatever desktop I am on to do so, then I can have a single 1440, but dual monitors forces me back to 1080.
The dock is using a 6000 series chip. I am using the latest deb of Displaylink right now, 6.3. And I am using the latest evdi 1.14.16. I even tried the most recent 6.x kernels, but they would not play nicely either. None of the earlier kernels are available in repos of current OSes.

Is anyone else experiencing this? It's killing my work flow!
