HDMI Disconnected after last update

I was able to connect to an external monitor up until yesterday, but when I updated the system (pacman -Syu), the system is no longer able to detect external displays.
Running `xrandr -q | grep HDMI` gives me
HDMI-1 disconnected (normal left inverted right x axis y axis)

I've tried two different HDMI cables and two different monitors, so it's not a peripheral hardware issue.
It does work when I try using a VGA cable.

I am using the linux-lts kernel and the nvidia-lts driver.

`uname -a`
Linux archlinux 5.10.53-1-lts #1 SMP Sun, 25 Jul 2021 18:43:53 +0000 x86_64 GNU/Linux

`pacman -Q nvidia-lts`
nvidia-lts 1:470.57.02-4
