I bought a acer led screen few years back.. ON the website it stated on site warranty 3 years so I was ok ill take this screen any day. When I opened it had a stuck blue pixel in the middle of the screen it was horrible on your eyes. So I called them... acer said I can sent it the courier will pick it up... A week later its back.. With the same bloody blue stuck pixel. I call them and ask WTF?They tell me they wont replace it because there is not enough deadstuck pixel in the middle.I told him its BS it was DOA from day one. OK so after long fight they refunded me (about a month in fighting ) (me sitting without a screen).
So from the same shop I buy a ASUS LED 2ms 24ich .... It comes arrives with a stuck green pixel in the middle of the screen?

First thing is I called the shop... They said courier it to them and I need to pay. (THE asus was also advertized with onsite warranty)That was incorrect but I just called asus they payed to pick it up. The shop send me a new asus screen with a RED stuck pixel

Now this was getting to me it took 4 months for 3 screen with stuck pixel.... SO asus again picked up my screen and send my the 3rde Asus that I have till date with 0 problems.
But let me tell you ASUS helped me with the only shop that advertised the screen with onsite warranty. Asus called them and they had to pay for the couriers so.1+ asus
