The privacy filter will work with any display, but it is important to check whether the dimensions are correct because not all 15.6" displays have the same aspect ratio - so read the dimensions and measure them on your laptop, otherwise in the worst case the entire display will not be covered.
If the HP Elite Notbook has a diagonal of 15.60 inches, it can be easily attached using magnetic strips. I would also fix the bottom and bottom centre with adhesive tape, otherwise the film will flutter back and forth when the screen is moved. The film has both a glossy and matt side. The protective effect is great, if you look at it from the side, you can almost only see black. Sharp images.
