RE: Change (upgrade) display screen resolution on Inspiron 15 3552

A higher resolution screen will require a new internal video wiring harness as well as the screen - and that may not be available for your model.  Don't count on parts from the 7000 series fitting the 3000 series -- remember, notebooks are not made by Dell (or any others whose name is on the outside, for the most part).  They're contract-manufactured by a few large Taiwan-based ODMs like Foxconn, Pegatron, Wistron, Compal and Quanta.  The two systems may have been made by two completely different manufacturers.

What you want to do will also void your warranty as well, if that's a consideration.
