My new Viewsonic VP930 [October] developed a lazy pixel 2 days back, very tiny pinhead dot in the centre of the screen that did not show on any page or a white screen or even a black screen, in fact it only showed up after I ran pixel buddy and saw it on the red screen.
I could have lived with it because it was such a tiny little dot and only on a colour I never use on my desktop, but I phoned Viewsonic and told them about it, explained it was upsetting me because I had spent a lot of money on this monitor and now I had a fault.
Viewsonics policy is excellent and though they say they will swap for 1 dead pixel, mine was a sub pixel and technically not within the the swap out guidelines.
As I said above, I phoned them 2 days back and a new perfect VP930 arrived this morning. God bless you Viewsonic and may all your panels be as perfect as this one...
