Hi. My monitor is GB2488HSU IIyama. Sometimes i can see on screen weird little spot,screens:
Not my screens,but the same.
When i am close to monitor it looks like smudge. Screen:

But. When i go away few meters to rest in bed it looks like this:

But this doesnt look like bad pixel. More like smudge or something. Also this doesnt appear always. Sometimes is visible,sometimes not. Any ideas?
Also why sometimes i can see this and sometimes not? Any explanation?* **
Somebody said that i have defective hardware. So exchange my monitor?
Also actually is my 3rd day without that thing on screen.
Please share your opinion.
