HP ProBook 4340s

LCD panel we found inside this model.

Opened 2 times, same panel each time. A good sign, but makers do switch suppliers mid-run — in our records, 56% of models opened more than once had different panels inside. Check the label on your panel before ordering.

How to confirm your panel

  1. Remove the bezel and lift the panel enough to see its back.
  2. Find the sticker with the part number (e.g. LTN133AT16 302). Ignore the laptop maker's own part label.
  3. Look that number up here, then check its Substitutes list before buying.
