Why my laptop display getting black dot

Hi @themc28700

Post an image of the display, showing the problem back here in your question so that others can see what it looks like. Here's how to do this on ifixit Voeg afbeeldingen toe aan een bestaande vraag

Has the laptop been dropped or gotten wet at all?

Try connecting an external monitor (TV?) to the laptop and check what the display is like on it and check if it also shows the black dot or not.
