Need advise on upgrading HD+ (1600 x 900) of Latitude 5470 to FHD IPS screen
Hello!
The LG "053X2G LP140WF3 SP D2" 14" is the only matte IPS screen currently available in my area. It should work in my laptop but before I buy it, I need clarity on the following things:
1. I read in some amazon laptop screen listings that you need 2-way video cable for an FHD screen. I am aware of 30 pin connector but should I be worried about this so called 2-way video cable.
2. Is the process of changing the screen in latitude series simple like for example it is on an HP Probook or is it complex? If it is a little bit complex than I would rather do it myself rather than letting the screen seller do it.
3. What other factors should I watch out for when upgrading a laptop screen on latitude 5470?

It looks like on this model, there are only two cables - one for touch and one for non-touch.
the service manual will answer the rest:

Thanks for responding. AFAIK the touch screen would require a 40 pin connector. Since my laptop has a non-touch screen therefore it should have a 30 pin connector. Am i correct to assume that any screen that has a 30-pin connector should work with my laptop?

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.
