Scrcpy wont open window android to android

Does not matter whether ran on android phone or samsung s9 ultra tablet when scrcpy is ran this is the result android to android

when i run scrcpy from my MacBook pc -window opens and I see remote screen so obviously Mr.Termux on android and scrcpy are missing something , I need to know what the problem is.

Thanks
