I was able to do a search and would recommend reporting a fault in such cases. Such a coil beeping is apparently known at Dell, but they state that it should be "within specifications". However, if it is loud and annoying, I recommend reporting a fault and sending it in. That way it can be checked after being sent in and an appropriate solution put together. Regarding the question of resales, our processes are basically as follows: We check the product and send it in if it is defective, of course. We then check it again and decide whether it will be resold as "reconditioned". We state the technical condition of used suppliers. Example: - Very good: Fully functional. Some light scratches or signs of wear. - 100% original parts

I was able to do some research and it looks like the manufacturer uses the same EAN codes for different revisions. Unfortunately, we can't separate these and so as long as there are still some of the previous revision in circulation, there would be a chance that a copy of a previous version would also be delivered. So no, we do not separate "production batches".

It looks as though it has a 10 bit display. Please follow the link given below: https://www.displayspecifications.com/en...
