Just bought this monitor GB244HSU 144Hz feels absolutely awesome, compared to 60Hz. But I have 2 questions about this monitor: 1) I noticed this dark spot ~0.5cm in diameter. It's only noticeable on black/gray colors.

Screen:

 
Its not my screen. Just found in internet to show what it looks like!

Should i rma?

Moving thread to general hardware.
 

Personally its not bothering me, but i dont want problems from buyer when on future i wil sold that monitor.

Hey again. Today i turn on monitor and that thing just dissapear. Any ideas what that was why disspeared itself?

 
That was looks like a smudge. And any ideas why it dissapeared itself? What can it be?

That was looks like smudge. That doesnt looks like stuck dead pixel for me. But it dissapered itself ,when i turn on monitor today.

Something like this:
 

I bought monitor 2 weeks ago. In first few days i noticed weird smudge on a screen:
( not my screen but the same symptom ) . I dont have camera to make screen. I was tried to remove this by finger but not helped.
 

 
 
But. When i went away few meters to rest in bed it looked like this:
 

 

 
 
Anyway it dissapeared itself after 5-6 day of use. Now i cannot see this. ANd question. RMA monitor or not? Why it dissapeared? Keep monitor ?

Would you have paid the same amount if you had known about the "issue"?
 
When I buy something new I expect to be just that.. This could even be the beginning of something else. However, if you say that it disappeared I don't see how you could RMA it since the problem is not there anymore. Keep a close eye on it and if it appears back RMA it.
