I have went through 3 of these Phillips AMVA monitors, 2 had dead pixels and the first had flashing pixels: https://www.philips.com.au/c-p/BDM3270QP_75/brilliance-led-backlit-lcd-display-with-multiview
Apart from the dead pixel, the monitor is fucking great. I really enjoy the 3000:1 contrast ratio, and the colours are superb. But lately I've been thinking that eBay stores might be getting inferior stock somehow. Is this at all possible? The reason I say this is because Phillips apparently has a zero dead pixel policy with these monitors.
Each seller has been reputable, and all monitors came in un-tampered brand packaging.
Are/is pixel flashing or dead pixels indicators of a bad panel, or is the longevity independent of this?
