Enabling HiDPI and HDR on a Mac

Please open the Display settings on your Mac, choose the TCL display model as the primary monitor, then click 'Scaled' to display all resolutions. Select a resolution with HiDPI support. Also, please enable the Display settings on your Mac, choose the TCL display model, and click on 'High Dynamic Range.' If you don't see the 'High Dynamic Range' option, it might be due to insufficient bandwidth on your Mac's interface. Try lowering the refresh rate.
