I am with you on this one, but bear in mind, the technician who is supposed to replace your display possibly only knows the part numbers instead of their specs.<p>I faced a similar situation too (some years back) - I own a Sony Vaio and my display had some issues too. Basically, under the hood, the display is either an LG or a SAMSUNG if your laptop is by a good brand (LG/SAMSUNG makes the best displays, Apple, Sony, everyone else uses displays made by them), or it's made by some cheap Chinese company if your laptop's brand is not so reputed.<p>Also, the same laptop has multiple replacement parts for the same item. In my case, my display was originally a Samsung, but my replacement was an LG. But the appearance of the parts looked exactly the same, but underneath, my replacement display was 1080p, whereas originally it was 720p. Though, my maximum display settings still allow me to use only 720p.<p>Think about it, just a slight variation in part numbers could mean a LOT!<p>This is when I learnt that despite a laptop belonging to the same model number, it could have various part numbers for the same item. Hence, these technicians end up memorizing the part numbers instead of the technical specifications of the parts. I am not talking in support of the technician though - By all means, he IS SUPPOSED TO KNOW what technical features are inside, but given the appearance and complexity of the part numbers, this could be very difficult for one when dealing with thousands of components every month. Give the guy some benefit of doubt, but don't forgive Dell, ever.<p>Cheers!
