Connection and commissioning were quick and easy. The picture quality, brightness, contrast, color intensity and resolution are super. However, I had both on the first device and on the second device, that I then ordered a defective pixel that does not even let himself repair with software or hardware methods. Disappointing for such an expensive product. I will now try the predecessor PB278Q. The predecessor "only" a PLS instead of the newer AH-IPS panel, but the PLS panel (according to [...]) from Samsung and the IPS panel from LG. As for the quality, so I've got more confidence in the former brand and hope for accuracy at the pixels.
