Better replacement screen P50

2020-09-14, 13:26 PM



I want to replace my broken laptop screen on my thinkpad P50 20EQ with a better screen. Someone recommended the N156HCE-GA2 to me. Is this compatible with my laptop? Resolution, connector and size seem legit. 


Thank you!

Are you looking for a 4K (UHD) screen?  If so, Lenovo lists 00NY498 as the only compatible panel.  I believe it is a Sharp LQ156D1JW05-E LCD panel with an eDP connector.

P50 will work with almost any screen you can fit the connector to. I haven't tried the N156HCE-GA2 but B156HAN01.2 (FHD) and B156HAN04.5 (120Hz FHD) works fine so if you make sure the holes, connector and size matches it should work out of the box.

I owned a P50 with the FHD screen, also the P50 with the (non-touch) 4K screen. The 4K was my home machine, the FHD was my road machine. I could NOT use the FHD display. It was HORRIBLE on the color gamut (45% ). Even worse, when using the P50 4K and moving to the FHD screen it made me realize that Lenovo had two design teams working on these (I'm just assuming here, but the screens are two extremes of the spectrum). I decided to find a solution to this problem, and settled on the following 72% gamut LCD:


LP156WF6 SP B5

BE REALLY CAREFULL! Some compatible LCDs are NOT compatible AT ALL. Worst case scenario, you will do TWO things! Blow your main power fuse and the LCD main power fuse on your motherboard. REMOVE ALL POWER WHEN SWAPPING LCDs, including your BATTERY! If you see a flash of light on your LCD and then nothing, you blew one or more fuses. Use LCDs that others have found to work! As bad things can happen when using "compatible" LCDs. Also, make sure that the part number (in this case LP156WF6 SP B5) is part of the LCD label. If the part number is not the same, it is a "compatible replacement".


The LCD replacement was probably the best upgrade I did to that machine! I could actually use both P50's, without losing my mind.

Hopin all of you are fine



I am experiencing the same discomfort with my screen.

Do you mind to share the link where you've bought your new LCD. It seems that its part numb is LP156WF6 SP B5, am I correct ?

Thx for your help

Re:Better replacement screen P50

My P50 laptop fell in a hotel room and the 4K LCD was cracked. I bought an AUO B156ZAN02.1 as a replacement, which I believe is the model used in the P51 or P52 and has slightly better specs than the original, while fitting exactly as the original display. It is 300 nits, 800:1 contrast ratio, 100% adobe RGB, and matte. If you previously had a FHD display you need a different cable (not sure where you get that from). I bought the display from thinking-world on ebay USA. Make sure to ask the seller if they have the exact model you are looking for and not a "compatible" part. I paid around $250 back in 2019.
