Hi ltt forum i have a macbook m1 air and a ps5 and i wanna buy an external display like the gigabyte m28u or more likely the acer nitro xv282k both of this displays have a a usb c input and a 15w power delivery my question is can i connect a usb c cable that powers my macbook and my display and powers all the usb a inputs on the display or do i have to use the usb b cable separately and if the answer is yes than what type of usb c cable do i need? thanks in advance!

My laptop isn't so powerful ,it doesnt have a gpu it is using on board graphics
