If your laptop was available in different resolutions, is it possible to upgrade to a higher resolution panel? Their site warns you to make sure the resolution is the same as the existing panel.
You have to do your homework, for sure. Electrical compatibility is sometimes easier to obtain than physical compatibility, because of different PCB shapes and bracket holes.
In this case, I've got a Dell e7240. Older but generally excellent Haswell ultrabook, save for a dim, dull 13x7 TN panel straight outta 2005. It was originally sold with either that using a 30-pin eDP port, or a 1080p IPS touchscreen which also uses eDP but has a 40-pin combined display and digitizer, plus beefier hinges. After a couple hours parsing this NotebookReview thread
and searching part numbers online, I've concluded I can swap just the LCD without dissassembling the base unit, but I'm limited to two options, both of which are out of production and becoming scarce:
LP125WF2-SPB1 -- LG Philips IPS 1080P -- $105-ish
LP125WH2-SPM1 -- LG Philips IPS 768P -- $60-ish
The first was used mainly in some Lenovo x240/250 models but is nearly a drop-in replacement for the OE 13x7 display in Dell 7240/7250 models, as long as you don't get mis-shipped the SPB2 which has a wider PCB. The second unit is an exact drop-in replacement and is what Dell should have used in the first place.
Part of me really wants the extra screen resolution. The other part of me knows my eyes are within spitting distance of four decades and can't handle that kind of nonsense on a small screen. Then again, Win10's desktop scaling options are much better than in past versions, so...decisions.
