Chosen Solution

Hello ! I just received a new screen to replace my broken OnePlus 5T screen. I thought it would be easy game : dissemble, plug and done. However, the result is not quite what I expected. The screen is upside-down and displays two times what should appear once (as you will see attached). Also : the touch screen is at the right place, as if nothing was different from a new phone with perfect display… Have I done something wrong… ? Do you have any solution? Many thanks in advance !

KasDing the only thing you want to check on is your connector. Make sure that the pins are straight and not bend sideways etc. Ultimately this sounds and looks like a bad screen. Return it to wherever you bought it from and request a new display.
