Hello, i got a 20 inches monitor, it works perfectly, and have no bad pixel. Unfortunately there is this "cloudy" part, which is very annoying.

I don't know if the monitor was badly handled during the shipment, but there are no visible damages externally.

Somewhere in internet i read that i should put the monitor with a white background for days, and wait. It's no dust inside, but also looks like it's not the backlight lamps, so i don't get what is it and/or if it's fixable.

Thanks

I had a Second hand TV that had that effect on a portion of the bottom. Dark colours it was practically invisible, light colours made it appear worst. No amount of use made it change.

Supposedly it was liquid ingress.

Looks like a "mura". A degradation in liquid crystal layer, caused either by excessive pressure, or more frequently by prolonged use in high temperatures.
I have a small ViewSonic lcd, with similar patch of uneven brightness close to the edge where CFL tube is located.

I posted one like this with a different pattern (but same effect) several years ago. I was told the panel is permanently damaged

If it is an actual glass panel fault and not a fault of the diffuser but chances of recovery are still very slim. It is not trivial to get the entire display panel open, they're not at all meant to be disassembled...
