8 inch radxa screen not working but hdmi is

#1

so basically as the title states i bought the 5b+ board and its working beautifully over hdmi (i am making this post from the board running debian os) but i cant get anything on the screen no sign that its even recieving power. i am using an anker power bank as my main power source but i know this isnt the issue as ive tried other power sources that work with full size laptops but still nothing. any help would be appreciated and dont be afraid to point out dumb stuff as i am still very new to these sorts of things

You need to enable the screen’s device tree overlay, otherwise it won’t be used.
