With the XPS, the best way to do display swaps is often to change the assembly. At least internally, Dell is using different connectors on the 4K LCDs compared to normal FHD panels. ***''As such, you usually need to change the cable and LCD. Due to that issue, it’s best to spec it out with a 4K LCD now if you can do so, or swap the assembly as a whole unit.''***
Typically there’s no issues on the board side as Dell uses the same board connector for the entire screen range*, so the issue is on the other side -- when you open the LCD shell.[br]

*During the HSW (Haswell) era, there were 2 machines I know we're either LVDS or iDP based on the base panel spec/if it was for gov't or corporate customers without a webcam, but used the iDP motherboard. At one point, I used 2 of those -- an E6440 and E7440. However, Dell no longer does that and they're all iDP. These horrible transition systems are total losses now when the screens die so we just chuck them :-).

With the XPS, the best way to do that is to change the assembly. At least internally, Dell is using different connectors between the FHD and 4K display so you need to change the cable and LCD - on the non-integrated cable machines. Due to that issue, it’s best to spec it out now, or upgrade the LCD assembly when you’re ready so you have all of the correct cabling.

*During the HSW era, there was LVDS and iDP boards on a few machines - I had two in production, an E6440 and E7440. However, Dell no longer does that.
