Hi hopanoid,
macOS does support daisy-chaining of Thunderbolt 3 devices using USB-C ports. However, daisy-chaining displays specifically using USB-C may have certain limitations or requirements that need to be met for proper functionality.
In your case, you mentioned using the LG Dual Ergo 27qp88dp monitor and daisy-chaining the second monitor to the first one using DisplayPort. It's important to note that while Thunderbolt 3 and USB-C use the same physical connector, not all USB-C ports support the full Thunderbolt 3 functionality required for daisy-chaining displays.
Here are a few steps and considerations to ensure proper daisy-chaining with macOS and your LG monitors:
- Verify Thunderbolt 3 Compatibility: Ensure that your MacBook Pro M2 Max has Thunderbolt 3 ports, as USB-C alone may not support daisy-chaining displays.
- Check Monitor Compatibility: Confirm that your LG monitors support daisy-chaining via USB-C. Some monitors may have specific requirements or limitations for daisy-chaining.
- Update Firmware: Check for firmware updates for both your MacBook Pro and LG monitors. Sometimes firmware updates can improve compatibility and functionality.
- Cable Quality: Use high-quality cables, especially for Thunderbolt 3 connections. Cheap or faulty cables can cause connectivity issues.
- Monitor Settings: On the LG monitors, ensure that the daisy-chaining feature is enabled and configured correctly in the monitor settings menu.
- Restart and Reset: Try restarting your MacBook Pro and resetting the monitor configurations to see if that resolves the issue.
If after checking these steps you still experience issues, it's recommended to contact LG support for assistance with the monitor's daisy-chaining functionality. Apple continually updates macOS to improve compatibility and support for various hardware configurations, so keeping your system up to date with the latest macOS version is also beneficial.
Good luck!
