Upgrade LCD Dell Inspiron 5577 to IPS 4K

Hi people, everything good?

I am studying the possibility of updating the LCD of my Dell Inspiron 5577 for a 4K IPS screen, I found this screen as an example: LTN156FL02-101.

I know there is a version of my notebook with a touch screen and 4K, so I believe that what I want to do is possible.

From what I've researched so far, the only thing I need to do is to change the EDP cable, my current has 30 pins, and the 4K screens use the 40 pins, I found the 40 pins cable even used in the 4K version of the Dell Inspiron 5577 with 4K touch screen.

This image below would be the cable I bought to do the test, it would be 40 pin, even used in the 4K Touch version of my notebook.
Only difference from it would be the pins that go on the LCD, which are 40 Pin, all remain the same, so I think it can work



I believe that because my notebook exists this version 4K, should work, what could harm me would be something on the motherboard that would be different between versions. Because the rest are all the same, both models have dedicated video card that stand the quiet resolution.

Anyone here ever made any kind of change like that and had any positive or negative results?

What do you think?

Thank you guys!!

 

The connector on motherboard side is probably different. Similiar situation to Inspiron 7577 and G5/7.

 

No, they are identical, the connection on the motherboard is the same ...

 

My mistake. I'm not sure, but try to find pinout scheme if possible. These may differ as well. Or try to find pics for 4k motherboards and check if the markings are identical with yours.

 

I think I understand what you mean

figure out if the pinout despite being 40 pins on the motherboard of both models, each pin can be of different utility or even be in different position, correct?

I think I understand what you mean

see if the motherboard pinout can have each pin a different utility or even be in a different position, correct?

Although both models are the same, the pin positions and their utilities may change

Motherboard Dell 5577 - My Laptop


we can see that they are practically the same

where the 7559 has a model that is 4K
probably works on my model 5577
pinning on the motherboard is the same, I made the purchase of the Dell 7559 cable, where it accepts to connect the 40 Pin 4K LCD

 

Hello friend, I would like to spend here my experience in trying to do this upgrade in my notebook.
Unfortunately it did not work, I switched the 30 pin cable through the 40 pin cable, bought it and took forever to arrive.
When I turned it on simply it did not give video on the 4k LCD, sad.
Maybe it's the motherboard pinout that should change from one model to the next.
