Jul 28, 2015 6:55 PM in response to makaylalalalaby ChitlinsCC,Way too little information. Details!
Tell us a Story - with a beginning, a middle and end. We need to understand everything that you know and have experienced.
If this issue is new, tell us what immediately preceded its onset - add software, upgrade or update? New equipment?
A screenshot MAY show us what your are seeing -- COMMAND + SHIFT > 3 will save the entire display image to your desktop on a Mac == the camera tool here or drag & drop in your reply.

Jul 30, 2015 8:25 AM in response to makaylalalalaby Kurt Lang,It's commonly referred to as a stuck pixel. That particular spot on the monitor isn't responding to the data being sent to it by the Mac, or the monitor's own refreshing of the on-screen data.
Put a dry, clean cloth over your finger and gently rub over the stuck pixel. It may or may not help, but it's about all you can do.

Jul 30, 2015 8:34 AM in response to Barry Hemphillby ChitlinsCC,I wanna see a screenshot!
If "green pixel screen" is NOT present in it, then its display hardware = take it in, indeed. If present (WHATEVER that description means), it "could" be hard/soft-ware rooted.
Remember this one? Re: Small white square appearing on screen - it turned out to be caused by a failure to properly end (and clean up) an Apple Support "takeover" of the OP's Mac.
Lotsa scripts and/or software can "overlay" the entire display with a "screen MIDground"

Fine for a 'pixel' (maybe not, see Re: Small white square appearing on screen ) but a "Screen" ON a display?
curious to see if OP "calls back"

Jul 30, 2015 8:52 AM in response to ChitlinsCCby Kurt Lang,Fine for a 'pixel'
Yup. I'm taking it literally and see if that is indeed what the OP means.
Unfortunately, a screen shot may not prove anything. Screen grabs are directly pulled from the display buffer, not what the monitor is actually showing. So if it is a stuck pixel, a screen grab will simply show what data that pixel area is being sent to display, not what it's doing.

I believe that is the point that CCC is trying to make. If the screenshot does not show the problem, then the issue is with the display itself. The correct information is being sent. If it was something else, it should reflect in the screenshot. I've used that to diagnose problems with iPhone displays as well.

literally... out of context !! " ... a green pixel screen on my display monitor. ..." - heh heh
On the Contrary, the "Absence" of anything visible in a screenshot proves that it IS the display itself or connection thereto. (My Pismo's display is way past screwy, but screenshots are fine as are external displays)

Heh! Not contrary, that's exactly what I meant by:
a screen grab will simply show what data that pixel area is being sent to display,
i.e. the green pixel is absent from the screen grab.
And hey! What do you mean by my avatar "kills" you?! What avatar?

Jul 30, 2015 10:08 AM in response to Kurt Langby ChitlinsCC,A nod is as good as a wink to a blind horse...
While I'm on a quotation spree, I am "... quivering with antici . . . . . pation " to actually see a screengrab
I think what tickles me was I mistook your 'self-portrait' for an 'avatar'... maybe its because the 'selfie' was take in a mirror?

staring at the above images a while IS Disturbing!

Jul 30, 2015 11:28 AM in response to makaylalalalaby babowa,Here is Apple's official document on it:
About LCD display pixel anomalies for Apple products released in 2010 and later - Apple Support
or, for products released before 2010:
About LCD display pixel anomalies for Apple products released before 2010 - Apple Support
As Barry said: take it to your nearest Genius Bar.
