Sidecard resolution FIXED

Hello, i've seen a lot of post like this Sidecar resolution change - Apple Community on the internet and i've been experienced the same problem, but i founded a alternative and solution :)

Using a displayplacer (thanks jakehilborn) for a experts users (this tool use command line :x) or using the app Display menu with a friendly interface (its paid :x).

And finally i want to say thank you apple for all support, with fone and massage for 2 days along!!!! I love it!!!!!!

I hope this post may be useful for the community :)
