Hey Guys!..
 
I have a problem with my secondary monitor, and it's something i've recently noticed.
 
When i drag stuff with a white background (Google in a browser, Teamspeak, heck even this forum :P) it is as if it creates kinda this white shadow where the pixels has just been black or other color. attached an image here: 
 


I don't notice this AT ALL if i drag a window like spotify which is completely black with a white text on it though, but Teamspeak which i have over there i notice it every time i drag the window, even slowly. Even browser windows, and it kinda makes me mad. 
It is a BenQ G2420HD which i've had ever since it came out so it's quite old. I don't think there is any immidiate worries.
 
I've tried changing the VGA cable to an HDMI cable just to check if it was the converter, the cable or something else. Didn't fix it though! 
 
TL:DR could it be pixels slowly dying and thereby being slower to change color back from black to white? (Picture related)

Most probably. That is like extreme form of ghosting!. :p

Well, yea, it's quite annoying.. fortunately it's my secondary screen, but i'm still annoyed by it. I didn't notice it before the other day though .. so yea, i usually just use the monitor for browsing anyways.. But it is a 60 hz, 2 ms gaming monitor.. It didn't do it when i used it as a primary monitor like a year ago 

It is as if i drag a tail of white text behind everything .. it's annoying to say the least though

Just like the good old days where you could make your mouse pointer leave a trail. ;)

You can still enable that in the control panel under mouse settings.. but yea.. It's quite annoying :).. well.. Gives me a reason to spend more money!
