2nd HP 24 mh Monitor will not connect after update to Sonoma 14.7.1

M3 13 inch MacBook Air. Was running two HP monitors as external displays. Ran them both through a dongle and one of the USB ports. Absolutely no problems. After updating to Sonoma 14.7.1 the second monitor is no longer recognized. I checked all cables, dongles, and ports on the M3. One monitor will connect. I can switch ports and monitors and it still connects. Downloaded latest version of DisplayLink. Changed connection permissions to ask always. Asks for everything but the 2nd monitor. It will connect to an Acer monitor and also to Home Theatre no problem so it may be a HP specific issue? Was going to upgrade to Sequoia but now only if it fixes this problem. Not enthusiastic about downgrading to 14.6.1 but have Time Machine backups to do that. Any help with a fix that works would be appreciated.
