Lenovo Y50 Screen Replacement?

I have a non-touch lenovo Y-50 and I've had numerous problemswith it that include the screen flickering to it just completely turning off. I have the fhd version but I was wondering if it would be possible to replace my screen with the 4k screen from the 4k version of the laptop and if not, what is the best screen replacement.

Almost certainly you couldn't replace the screen with anything else apart from the same type.
If it is faulty then note the part number to find a replacement.
