There are many good panels that will work out of the box for your L440, you could install a HD+ (1600x900) or a FHD panel (1920x1080).
A very common upgrade are FHD panels, the best being the ones like the AUO, B140HAN01.2, AUO B140HAN01.3 or Innolux N140HCE-EN1 rev C2.
When sourcing panels, make sure you get original models and no "compatible" ones. Compatible panels will do work though, but the ones above are known for having excellent display qualities.
