I used to sing the praises of Asus warranty exchange in the UK for monitors, a couple of years ago it was the best warranty experience I've had in the industry and I used it a few times. It is an door step swap system; quick and painless. You'd e-mail them, they'd setup the return and nearly always the next day you'd have a courier turn up and swap the panels over with a new or fully checked one there and then. It was done and dusted with the minimal of fuss and wasted time. I'd now specifically recommend you buy another brand if you are even in the least bit fussy about the quality of your panels because I've had nothing but problems. That or just return it to the retailer under the CCRs (Consumer Contract Regulations), buy a new one until you have a perfect panel, then just hope and pray that it doesn't become faulty! Asus are clearly just operating a cheap revolving door system and none of them are checked for faults. I suspect as long as the faulty ones coming back in turn on they are issued new serial numbers, packaged up in the same battered boxes and shipped right back to customers. Which basically means they are wasting the customers time as almost every panel shipped to replace a faulty panel will actually be faulty as well. Since June the 15th when I received my new monitor I've done three returns and I'm about to open my forth return as the latest panel is also faulty. Every single panel I've received has been riddled with faults, be it flickering, damage, backlight bleed or half a dozen dead pixels! It also doesn't help that nearly every single one has been automatically rejected right off the bat even after including proof of purchase and detailed fault info in the initial return. They want crystal clear photos or videos of dead pixels or faults before they'll even consider opening a return. I can understand why but this back and forth trying to get the perfect pictures they'd accept is a waste of the customers time and a couple of years ago it wasn't like that, they'd actually trust customers. I've asked them to send me a new panel on the last return, considering the number of returns I've had and they have just flat out ignored it. I'm guessing cost cutting and abuse is to blame, but now a once great service has been reduced to something that is barely fit for purpose. TLDR; The once great Asus Monitor warranty service in the UK is a pain to deal with so just avoid using it. If you buy a new panel and it has any faults I'd suggest returning it to the retailer under the Consumer Contract Regulations and buy another new one. Then pray it doesn't go faulty during the 3 year warranty..
