I have just bought a Z5P and the pixels are slightly visible, especially in parts of the screen where a light color is displayed (such as white or Yellow). Is that normal?
Yep I can see the zigzag, is that a Z5 premium? That is something I noticed with all the triluminos ips panels but I never seen something so accentuated, it may be related to some white balance, did you try in safe mode? Does that happens all the time or just when the battery runs a bit low?
Yes it's on a Z5P. They are always visible. Even when battery is full or when in safe mode. If it's a problem (and it probably is), it's a hardware problem.
