By this standard, Class 1 displays tolerate exactly zero dead pixels or sub-pixels which makes them expensive and uncommon. ISO 13406-2 guidelines which specify an “acceptable” number of dead pixels by display category. What do you feel? Would you live with a dead pixel if you just spent £550 on a new monitor? How many dead pixels is it before you class it a problem? Surely not 18 or 19? From my own point of view, I was always under the impression that a couple of dead pixels was classed by the industry as acceptable, although I know that if I buy from Amazon in the UK it is easy enough to send it back, without any issue. Matthew is forced to either deal with the annoying dead pixel, or lose a rather hefty £137.50 overnight. Above: Brand new £550 Acer XB270HU Predator Nvidia G-Sync monitor. In this case a quick calculation shows that 25% of £550 is £137.50. The customer services representative told him that if he wanted a refund they would need to keep 25% of the price he paid. Matthew then asked if he could please have his money back – the dead pixel was distracting. The staff member at ARIA said they wouldn't replace the panel as up to '19 dead pixels' on a 27 inch 2560×1440 monitor is considered acceptable.

I can't help but feel that the general mass market audience might not even notice a dead pixel, but I am certain that many obsessive, quality driven KitGuru readers would find even one or two dead pixels a serious distraction. The general ‘ruling' seems to be some dead pixels are perfectly acceptable. Often, it would appear that the retailer involved is under no obligation to replace a panel with a couple of dead pixels – even though it is brand new.
