Strange black dot on my LED screen

[Jimbob1]

For some reason, I just noticed a very small black dot on my screen, I have tried wiping it off, spraying some special LED spray onto it and it is still not working. I don't know what it is.

As you can see, it is very faint but I have fairly good eye sight and can notice it when on a white screen.

Well, that is the reason I have posted this topic because I really don't know.

try another monitor if u have one. if u dont have another monitor use a tv eith hdmi.
if u dont have a tv i think you have to play with a tiny dot on your screen wich doesnt really matter

You might want to indicate where that 'dot' is. At first I thought you meant dead pixel but looking at your image, the only semi-obvious apparent irregularity is a circle near the middle that looks like a round stain of some sort.

If that's what you are talking about and it was not there before and you are 100% certain it isn't a stain/burn mark on the surface, it could be minor damage to the LCD's structure from an impact or excessive pressure.

It could also be a localized manufacturing defect that you never noticed before or that manifested itself over time - ex.: a spot of glass that had a bubble on it for part of one of the various processing steps that caused it to age slightly differently from the rest of the panel.

I have tried wiping it off and it isn't coming off. Because it's so small I haven't noticed it before and if I'm honest no one comes into my room nor touches my LCD screen to damage it.
