My mac doesn't recognize the 2nd monitor

I've gone to "Display's" in System Preferences, but it doesn't show the external monitor. How can I get it to recognize it? I've checked, unplugged and replugged in all the cords


MacBook Air 13″, macOS 12.5

If also looks like the Lenovo has HDMI and DisplayPort inputs, which also gives you the option to use either a USB-C to HDMI adapter or a USB-C to DisplayPort cable.
