The AW3821DW seems a decent monitor to try out

For Dell, monitor purchase, I am in dilemma to extend the warranty from 3Y Basic Hardware Service with Advanced Exchange after remote diagnosis to 3Y ProSupport with Advanced Exchange after remote diagnosis or 4Y Basic Hardware Service with Advanced Exchange after remote diagnosis. Both also same, cost extra RM 131.13

Thank you so much for the respond. I know right, I have decided to extend it till 5 years with more additional charges, just for peace of mind

And 1 more question, if I would like to connect my windows laptop USB C together with my MacBook Pro USB C to the monitor at the same time, since my windows will utilised the USB C port, then how can I connect to my MacBook? Either HDMI or Display Port? Then which 1 is recommended? And in this case, the HDMI or Display Port will not be able to charge my MacBook unlike the USB C port I guess.
