Hi everyone!

I have a Precision 5520 mobile workstation with a UHD touch screen. While it is a razor sharp screen it unfortunately gives me a lot of issues with scaling that I didn't expect at the time when I configured it. I would really love to downgrade the screen to an FHD screen for both performance and battery reasons.

I already spent countless hours researching whether or not this is technically possible. What makes things worse is that there is a lot of contradictory information about this subject.

E.g. here it says about the very similar XPS 9560:

https://www.dell.com/community/XPS/XPS-15-9560-screen-replacement-UHD-touch-to-FHD-non-touch/td-p/6114329

Which suggests, that it is possible. Also, an e-mail exchange with the Dell support (about my specific model) said the same (I asked whether this is possible, and the answer was "yes, you have to order part N° N98CY).

Then, there are a lot of parts sellers, who say it is not possible because of incompatibilities between this 30-pin and 40-pin display connector, e.g.:

This is very frustrating.

I find it hard to believe that Dell acutally uses two different types of mainboard depending if you initially configured the laptop with a UHD or an FHD screen. Could somebody give me a final statement on this? I would like to avoid ordering a screen assembly and disassembling my laptop just for trying it out.

Thanks in advance!
