Hi everyone,

I just discovered a small mark on my monitor this evening.  It's a small bright spot, maybe a little smaller than the eye of a needle, and is in the upper left hand corner of the screen.  It's fixed there and doesn't show up when I take a screenshot of the area.  I can make it out easier when the screen is white and not black or a dark color.

You can barely notice it, but it's bugging me.  I suspect it might be a dead pixel, but I searched for dead pixels on Google images and it doesn't really look similar.  I'm on a Macbook that's less than a year old.

Please help. 

Thanks a lot!it probably is a dead pixel. One of my old CRT monitors had a number of black "specks" in the middle of the screen. Count your BLESSINGS that yours is in a corner  BC, thank you for the PROMPT reply!  This looks a little different from the images of dead and stuck pixels I've seen.  The spot on my screen almost looks like a really small, SLIGHTLY bright blur.  Do you think it's still a dead pixel?  I've heard you can fix these by gently applying pressure with a pen cap or something--is that true?


depends. Is this a LCD or a CRT?

if it's an LCD it could actually be a problem with the backlight; as an example my really old thinkpad laptop has a small "ring" around the middle of the screen at the bottom, which is where the wires enter the Backlight; this portion get's hot enough it changes the brightness of the light coming out, affecting the view on the screen. It's almost 2 inches wide but generally not distracting.

To it's credit my old laptops screen was Designed to come apart entirely without tools for projectors so it was easy to CHECK inside.



This might be similar to what is happening to your DISPLAY, if it is LCD, perhaps a warm component is in that corner and has caused a similar (harmless, by the way) warping to that specific corner.
