A black dot appeared on the Matrix (Monitor). Are there problems with the monitor electronics?
A black dot appeared on the Matrix (Monitor). And only recently, I replaced it. Such problems were on the previous matrix. Possible problems with the monitor electronics ??? Or is it still "dead" pixels (since the matrix is not new) ??

It could be a dead pixel. This happens. If I'm not mistaken, then this is not a warranty case (if it is one, and not half the screen)
It's definitely a dead pixel. If the electronics are faulty, then the result would be more noticeable - stripes, distorted colors, flickering.
