I posted this on the NVIDIA forums, but thought it might be helpful to
cross-post here.

I just tried the 460 server driver solution. This did not work for me
and I still have the display port bug.
I have an AMD 3800X, 64 gb ram, rtx 2080 super, fresh install of Ubuntu
20.04 kernel 5.8.0-55, with 3 identical 4K monitors, (1 on HDMI, 2 on
DP). The opensource driver continues to work just fine, but we need CUDA
for our science to continue.
Here are the outputs from nvidia-smi, uname -r, and xrandr. Note that
all monitors should have 4K options.

I tried the nvidia-driver-460-server solution. Sadly it did not work for
me.
The display port connected monitor resolutions are not correct with the
460.73.01 driver version showing 1080p when they should be 4K.
