second monitor 'input signal out of range'

Hi, I have a macbook pro connected to a HP 2009 v monitor, which up until recently has been working fine. I've now got a message on the monitor saying 'Input signal out of range, change settings to 1600x900 - 60Hz'. I've tried changing the display settings in system preferences and changing the display isn't working, even when I try changing it in safe mode. How do I fix this?

MacBook Pro (2020 and later)
