Just a post to say HP are spot on with their warranty again. Logged a call yesterday evening and was called this morning to be told they are sending out a replacement panel. Noticed that the colour was no longer uniform horizontally. White appeared white on perhaps a 20% verticle block on the right of the screen and the rest was a reddy/brown hue. No issues from HP so far, sending one out without any hassle. Glad I bought HP, their warranty we use weekly for enterprise parts transpiring to the consumer market nicely and pretty much second to none compared to some other brands!
