RE: Need advise on upgrading HD+ (1600 x 900) of Latitude 5470 to FHD IPS screen
No - absolutely not. Notebook screens are coded in setup by EDID - only those screens that Dell has coded into the BIOS table are guaranteed to work. Anything else may display nothing until Windows loads (i.e., no BIOS/UEFI page), may not work completely (artifacts, split or corrupted screens) -- or may not work at all.
You need a screen known to have shipped with this model system.
