It is hard to tell by the way you have asked your question. You have left out some very important information to be able to properly address your question. What is the exact model in your LCD?
Added the following in edit:
If you are wondering how to check the panel you can do two things:
1. System Preferences > Displays > Color > Color LCD > Open Profile > Line 17 (under "Model")
2. Issue the following command at a terminal:
ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6
Please post your LCD model number in this tread so we can address the problem.
It appears that LCD should work in your Laptop. The LCD in question LP154WE3-TLB1 LG-Philips is the High Resolution option for the mid 2010 MacBook Pro. The Mid 2010 MBP and the Mid 2009 MBP use the same LVDS cable as can be seen here. The LCD in your laptop LTN154BT08 Samsung is a standard resolution screen that could also be found in the Mid 2010 as can be seen here
I mention the following because Apple is known to throttle everything down from the original manufactures specifications. Depending on what Apple has done with the BIOS in the NVIDIA GeForce 9600M GT with 256 MB video chipset for the Mid 2009 MBP and the incorporated drivers you may or may not get the High Resolution the screen is capable of. If you install it and don't get the High Resolution I suggest you go to the Netkas forum and inquire about a fix.
