Double, triple check your g9 folks, I have gotten 3 monitors from an Indian competitor, and so far all have at least 1 dead pixel of at least 1 color. (1 with 2 bad pixels)
The standards of G9 QA is really shocking, here goes another I have to return.
Not something you expect after forking out over 1k for a top range monitor from Samsung. Do not keep it in the box after you got it waiting for build etc, test it immediately.
I've checked mine over twice now on all colours, white and black and I have no dead/stuck pixels. Guess I am one of the lucky ones .
