After weeks of research and return of various monitors wg. Headache I have now finally decide for this model. NO Flickering (PWM fibrillation), brilliant image, low power consumption (which was not the decisive, but at 6 monitors it's gratifying), no halos, no power supply hum, no dead pixels. Prima result with various monitor-testing programs.
The many complained glitter (which had almost stopped me to order it) I could not make to happiness. My light source is well above the monitor or the window is also behind.
Super I find the ability to switch directly on the screen - so I can switch between 3 connected computers and herswitchen.
