In web, https://www.smspower.org/maxim/HowToProgram/Stopping, it says:
; Turn screen on
ld a,%01000000

but in code Helloworld.asm is written:
; Turn screen on
ld a,%11000000

So what is the correct : %010.. or $110 ?

Both are correct. The relevant bit to switch the screen on and off is bit 6 of the byte. The other bits do different things. See Charles's VDP documentation for details.

Its time to read the doc
