Been waiting for something like this all year and now it's here and i don't have my monitor with me. :|
If you are facing pixelated text issue when a M1 Mac is connected to external monitor (non 4k monitors) there is a work around now using a 3rd party app.
On another note, M1 Air owners are you finding noticeably worse battery life now after a year of use? If I take a rough estimate now it's around 10-15% worse for me now than when it was new.
