look for dead pixel tester programs on google
30 Inches
several cuse 1 stuck pixel is only a little bigger than a piece of hair
try massaging the spot. Sometimes it works sometimes not. If you look close at your monitor you can see then finite pixels. Just guess at how many there are.
It’s probably more than one. A single dead pixel will be very tiny and pretty much square. If this black spot is bigger than a period, it is certainly multiple pixels. The only way to really tell how many pixels is to get up really really close to the monitor and count.
Dead pixel testers really won’t help you out – they don’t actually count the number of dead pixels for you. All they do is display different patterns that allow you to identify bad pixels. In your case, you’ve already identified bad pixels, so the dead pixel testers won’t do you any good.
If it’s bigger than the size of a period, it most likely more than one.
Check it with a magnifying glass. That will tell you. ~
