Does one have to indicate when selling a laptop, that the display was changed?

A friend of mine would like to sell his laptop, but is not sure if he has to indicate that the display was changed once.

I would be very happy to receive an answer and thank you in advance.

It just can't sell it anymore as an original from the brand because something has been changed.

I would always say something like that. You say, if you sell a car, yes, for example, that TÜV is new.
A swapped display, if it was not downgrade, is always good to mention. Means that the current one is still very new and therefore probably lasts longer. So it's more of a selling point. Why not mention it?

Yes, many thanks ^^.

If it was changed by the manufacturer eg in a warranty case?
