The part that is recommended is the screen only, it does not come with the metal brackets attached to the back of the screen with adhesive. You can remove those brackets and put them on the new screen, however I've found it pretty difficult to do that without bending those brackets, so I recommend ordering replacement hinges as well, which have those metal brackets attached.

As Ben says, the real issue doing this is that none of the replacement screens bought from Amazon, etc. come with the hinges. Dell, in their wisdom, have made these darned near impossible to remove from even a broken screen without either bending the brackets or doing yourself an injury. What happened to 'right to repair'? I've been happily replacing laptop screens for decades but this is a tall order!
