thanks for the tip!
so i also tried looking in the hardware ID on device manager + moninfo.
i still can't find what's the sub model = LG LP156WF6 - (SP)(B1).
1. are there any other software available?
2. i thought about the led as well, but i don't understand how critical it is.
generally what kind of significant differences can be between 2 units of the same panel?
3. any ideas if its possible to compare between the old screen (i don't have it) and the new one?
this is the information i have for the old one:
(from the sticker on the back):
barcode*
CN-0C3MWM-56252-52C-H1UU-A00
D/PN: 0C3MWM
15.6" FHD
LP156WF6 (SP)(B1)

new screen:
