Good program to use:

1) You can select which color to display (full screen) or auto rotate thru to find bad pixels.
2) You can use the pixel fix, which places a small square that you can move around. You place the small square over the "stuck" pixel and try to repair it. The square size is adjustable. If I remember correct default is a 5 x 5 pixel square.
Bought a new monitor and used it to see if I had a any bad pixels, did not have.
