thank you for your answer ! The thing is that i would like to know , after the connection of the aftermarket panel (that is not recognised by Dell) ,if there will be any functionallity problem . This innolux panel is respectable next to mine , but even if i change to 40 pin cable , the panel is gonna be functional 100 ? or does the bios of the laptop prevents some actions ? Thanks again for your answer anywayHave a look at this specs:

There are three models, depening on which resolution:
1080p -> 30pin socket
1440p -> 40pin socket
2160p -> 40pin socket
A 30pin socket will only work with a 30pin panel and a A 40pin socket will only work with a 40pin panel
you can compare your specific model on this side to the N173HCE-G33 :

Thanks for ur help really appreciate it!check if your laptop has a 30pin or 40pin connector soldered onto the motherboard. If it´s a 30pin, you can´t change to a 40pin panel
If it´s a 40pin connecotr on the motherboard, you can use the 40pin panel without issues
